Amblyosyllis rhombeata Grube, 1857 by monotypy.</p> <p>Diagnosis. Body less than 5 mm in length, dorsoventrally flattened, extremely fragile, with few segments; peristomium and last segment without parapodia and chaetae, each with 2 pairs of cirri. Intersegmental constrictions strongly marked, midbody segments typically trapezoidal in shape. Prostomium with 3 antennae, 4 eyes, and usually 2 anterior eyespots, sometimes ventrally located. Palps short, less than length of prostomium, basally fused, divergent, usually ventrally folded, and difficult to see dorsally. Peristomium shorter than following segments, with 2 pairs of tentacular cirri, and 2 nuchal organs, forming nuchal lappets, usually ciliated. Antennae, tentacular and dorsal cirri long, greater than body width, usually strongly coiled, sometimes forming skeins, smooth to indistinctly articulated, fragile. Pigmentary glands on dorsal and ventral cirri, sometimes forming distinct vesicles. Pharynx long, slender, highly convoluted, with trepan formed by several teeth, lacking median tooth. Proventricle proportionally small to body width. Ventral cirri large, located lateroposteriorly to parapodial lobes, similar in length. Compound chaetae, heterogomph, bidentate falcigers, numerous, present on all chaetigers, other types of chaetae rarely present; chaetae similar in all species. Pygidium with 2 long anal cirri, third length of dorsal cirri.</p> <p>Remarks. Species belonging to this genus appear to be uncommon and are typically known from damaged incomplete specimens. Distinguishing species is therefore difficult. The structure of the nuchal organs and trepan are useful characters. The method of reproduction not well known, although a mature male has been observed with natatory chaetae and one species is known to brood eggs in a gelatinous mass, suggesting that the species of this genus are epigamic (Pernet, 1998).</p> <p>Key to Australian species of Amblyosyllis 1 Nuchal lappets elongated, reaching middle of chaetiger 1..............................

All specimens incomplete; holotype (Fig. 1A) mature, epigamic specimen, with regenerating posterior end, 3.5 mm long, 0.6 mm wide, with 10 chaetigers plus regenerating segments. Body large, segments trapezoidal (Fig. 2A), especially those of midbody, fragile; some specimens colourless, others strongly pigmented with 2–4 dorsal transverse dark bands on each segment, more marked on midbody. Prostomium oval, posteriorly notched, with 4 large red eyes in trapezoidal arrangement, covering lateral margins (Fig. 1A). Antennae long, inserted on anterior margin of prostomium, with distinct ceratophores (Fig. 2B). Palps free, fused basally, ventrally directed. Peristomium shorter than subsequent segments, with 2 pairs of tentacular cirri, dorsal ones twice as long as ventral; 2 ciliated, elongated nuchal lappets (Figs 1A, 2A–C), extending to middle of chaetiger 1, with dorsal, longitudinal row of pigment (Fig. 1A). Dorsal cirri long, as wide as body, indistinctly articulated, with numerous dark, granular inclusions, irregularly arranged in 3 longitudinal rows (Fig. 1A). Parapodial lobes long, conical, with long, digitiform prechaetal papilla (Fig. 2D). Ventral cirri conical, large, broad, arising ventrolaterally (Fig. 2D), upwardly directed, with granular, dark inclusions (Fig. 1A). Parapodia with 16–18 compound, heterogomph chaetae (Fig. 2E), blades distinctly bidentate; within fascicle blades exhibiting dorsoventral gradation in length (Fig. 1C), about 100 µm in length dorsally, 43 µm in length ventrally, with short spines on margin; about 6–8 aciculae per parapodium, straight, distally pointed. Pharynx slender, with several coils (Fig. 1A); trepan composed of 6 teeth each with 5 denticles (Fig. 1B). Proventricle extending through 1.5 segments, with 11– 13 muscle cell rows. Holotype with notoacicula and capillary notochaetae, curved, digitiform, fleshy, dark structure arising from cirrophores from chaetiger 6 onwards (Fig. 1A, arrows); also, some ciliary bands present on lateral areas of first 4 chaetigers (Fig. 1A). Curved structure present on holotype missing on other material examined; function unknown.</p> <p>Remarks. This species is characterized by having elongated nuchal lappets and a trepan with 6 teeth, each with 5 denticles; no species of the genus has been described with such a combination of characters. The general body form is almost identical to Amblyosyllis granosa Ehlers, 1897, from Magellan Strait and Galápagos Islands. Ehlers (1897) originally described this species with the anterior margin of the pharynx lacking teeth; subsequently, Westheide (1974) reported the same species from Galápagos, describing a trepan with 6 teeth, each formed by a long, median cusp and 2 lateral, much smaller ones. Examination of 1 specimen of the type series of Amblyosyllis granosa from Punta Arenas (Chile) (NFMN 5318) did not reveal any teeth on anterior margin of pharynx, as originally described, so, we are describing the Australian material as a new species A. enigmatica. A previous record of A. granosa from Australia by Augener (1913) is also referred with caution to A. enigmatica n.sp. Augener’s material is not available for examination in the HZM and is presumed lost. Amblyosyllis granosa, however, could be present in Australian waters.</p> <p>Amblyosyllis formosa (Claparède, 1863) from European coasts is also similar to A. enigmatica n.sp., with regards to body form and the presence of long nuchal lappets; this species, however, has a trepan with 6 unidentate teeth (San Martín, 2003).</p> <p>Little is known about reproduction within Amblyosyllis. The digitiform structures arising from cirrophores of chaetiger 6 onwards have never been described before, and their significance is unknown, but they may be used in reproduction, since they are only present on the single epigamic specimen examined. Knowing whether such structures occur in other species of the genus would be of interest.</p> <p>Amblyosyllis spectabilis.— Haswell, 1920 (in part): 108, pl. 13, figs 4–10.

W.A. Haswell as A. spectabilis.</p> <p>Description. Body compact (Fig. 4A), longest complete specimen examined 5.7 mm long, 0.6 mm wide, with 13 chaetigers and 1 posterior segment without parapodia or chaetae. Colour pattern variable; holotype collected in 1920 colourless. More recently collected paratypes with several dark, violet transverse dorsal bands of pigment on each segment; intensity of bands differs between individuals. Antennae, tentacular, dorsal and ventral cirri provided with numerous, dark, small globular glands (Fig. 3A). Prostomium wider than long, margins rounded, with 2 pairs of eyes in open trapezoidal arrangement (Fig. 3A), and 2 anterior, ventrally located, small eyespots. Antennae long, 3 times width of prostomium, distinctly articulated, with numerous articles, arising on anterior margin of prostomium from distinct ceratophores (Figs 3A, 4B). Palps ventrally directed (Fig. 4C), forming double lip over mouth, nearly invisible dorsally (Fig. 3A). Peristomium about half of length of subsequent segments, with 2 pairs of tentacular and dorsoventral gradation in length of blades (Fig. 3D), length in midbody segments about 102 µm, 50 µm in length ventrally on midbody. Parapodia with 5–6 aciculae, straight, distally pointed. Pharynx long extending to chaetiger 5, narrow width, with several coils visible inside pharynx (Fig. 3A); trepan formed by 6 large teeth with 5 denticles separated by 1 unidentate, much smaller tooth (Fig. 3B). Proventricle small, located on chaetiger 5 (Fig. 3A), with 17–18 muscle cell rows. Pygidium small, trapezoidal, with 2 long anal cirri, half length of dorsal cirri.</p> <p>Remarks. Haswell (1920) referred his Australian specimens to the European species Amblyosyllis spectabilis (Johnston, 1865), a poorly known species usually considered as a synonym of A. formosa, which may represent a suite of sibling species. Johnston’s description of Gattiola spectabilis states that the pharynx is short and barrel shaped without teeth and long nuchal lappets are illustrated. In contrast, Haswell (1920) reported that teeth were present in the pharynx. Re-examination of this material has shown that it belongs to a new species, Amblyosyllis multidenticulata. This new species is characterized by having small nuchal lappets and a trepan comprising 6 teeth each with 5 denticles, which are each separated by 1 small tooth (Fig. 3B); no other described species of this genus has been described with this arrangement of teeth on the trepan. The most similar species is Amblyosyllis madeirensis Langerhans, 1879, which occurs along European coasts; both species have small nuchal lappets, similar colour pattern, and body shape. The European species, however, has only 6 pentacuspid teeth on the trepan, and the segment that bears the proventricle is distinctly larger than other segments (San Martín, 2003). We are thus describing the Australian material as a new species. Haswell (1920) also reported some specimens 10 mm long, with 14–30 segments, these were not available for examination and because of their size we suggest that they probably represent another species.</p> <p>Habitat. Occurring among bryozoans and others colonial animals, in shallow depths.</p> <p>Distribution. Australia (New South Wales).</p> <p>Etymology. The specific name refers to the highly denticulated trepan.</p></div> 	https://treatment.plazi.org/id/038287B3A205FFCDAB2727AAFC42F87B	Public Domain	No known copyright restrictions apply.

Antennae, tentacular and dorsal cirri smooth, club-shaped, tapered basally, longer than parapodial lobes. Compound chaetae heterogomph, blades slender, elongate, unidentate or indistinctly bidentate.Dorsal and ventral simple chaetae present on some parapodia. Pharynx shorter than proventricle, unarmed. Proventricle large, almost as wide as body. Some species brood eggs in gelatinous masses.</p> <p>Remarks. Fauvel (1923) synonymized Anoplosyllis with Syllides. Species of Syllides, however, have long, articulated cirri from chaetiger 3, and bidentate compound chaetae. Although these genera are closely related, San Martín (2003) proposed the resurrection of Anoplosyllis, and transferred species of Syllides with smooth dorsal cirri into the genus. Description. Body up to 2 mm long with 20 chaetigers; complete specimen 1.4 mm long, 0.2 mm wide, 20 chaetigers. Prostomium oval, more than twice as wide as long; 4 eyes arranged in open trapezoidal pattern and 2 distinct anterior eyespots, similar in size to eyes (Fig. 6A). Antennae short, similar to width of prostomium, clubshaped; median antenna inserted between posterior eyes, lateral antennae near anterior margin of prostomium (Fig. 6A). Palps small, shorter than prostomium. Tentacular cirri similar to antennae, dorsal ones longer than ventral ones. Dorsal cirri similar to antennae and tentacular cirri (Fig. 6A), smooth, club-shaped, slightly longer than parapodial lobes, some with distinct dark inclusion (Fig. 6B), which opens via terminal pore. Parapodial lobes elongate; ventral cirri digitiform, shorter than parapodial lobes (Fig. 6B). Compound chaetae heterogomph, smooth, slender, blades elongate, thin, unidentate, smooth (Fig. 6C), numbering 12– 18 per parapodium, with dorsoventral gradation in length of blades, 48 µm in length dorsally, 29 µm in length ventrally.

Ventral simple chaetae on posterior chaetigers, similar to dorsal simple chaetae, but thinner and smooth (Fig. 6F). Aciculae solitary, slender, distally rounded (Fig. 6E). Pharynx partially everted, short, probably through 1–2 chaetigers. Proventricle, massive, through 4 segments (Fig. 6A); number of muscle cell rows not possible to assess. Pygidium small, triangular, with 2 filiform anal cirri and compact median papilla.</p> <p>Remarks. The Australian material is represented by a few juvenile individuals and while they closely resembles the type material of Anoplosyllis sexoculata from southern Chile, they possess a shorter proventricle. At this stage we are referring them to this species, but mature individuals are really needed to confirm this.</p> <p>Habitat.

Eusyllis blomstrandi Malmgren, 1867</p> <p>Diagnosis. Body of medium to small size (10 to &lt;5 mm in length), cylindrical. Prostomium with 4 eyes and sometimes 2 anterior eyespots. Three antennae. Palps either entirely free or fused just basally. Nuchal organs as 2 ciliated grooves, ciliation extending sometimes to prostomium and peristomium, as well as other segments. Two pairs of tentacular cirri. Antennae, tentacular and dorsal cirri nonarticulated, sometimes rugose, with pseudoarticulate appearance. Compound chaetae; dorsal and ventral simple chaetae on some parapodia. Pharynx with mid-dorsal tooth, usually large and conspicuous, and incomplete crown of small denticles, anteriorly pointing. Pygidium with 2 anal cirri. Reproduction by epigamy (Garwood, 1991).</p> <p>Remarks. Eusyllis is characterized by having an incomplete trepan on the pharynx, with all teeth anteriorly directed, and a mid-dorsal, usually large, tooth. Species of this genus are typically large, even so the denticles of the trepan are small and sometimes difficult to observe, which can lead to misidentifications. Eusyllis brevicirrata Knox &amp; Cameron, 1971 from New Zealand, reported in Australia by Hartmann- Schröder (1985), reproduces by schizogamy (San Martín, pers. observ., on Australian material) so we suggest that this species represents a member of the subfamily Syllinae probably an undescribed genus (San Martín et al., in prep.). Australian material agrees with the original description based on New Zealand material. Eudontosyllis has been recently proposed as a synonymy of Eusyllis by Glasby et al., (in press).</p> </div>	https://treatment.plazi.org/id/038287B3A20FFFC5AB37225EFA3CFEE5	Public Domain	No known copyright restrictions apply.

Pharynx through 4–5 segments; opening rim smooth on one half and other half with small denticles (Figs 13A,F); material examined exhibiting considerably range in numbers of denticles present, from few to 20–24. Pharyngeal tooth large, conical to rhomboidal; pharyngeal opening provided with crown of about 14 soft papillae (Fig. 13F). Proventricle longer than pharynx, through 7–8 segments, with about 50 muscle cell rows. Pygidium with 2 slender, anal cirri.</p> <p>Remark. Material from all localities listed in the distribution has been examined by the senior author during other studies, and no morphological differences between them can be found. Molecular studies may be useful to confirm if this is a widely distributed species or a suite of sibling species. Specimens described as Eusyllis autolytoides by Hartmann- Schröder (1991) and Odontosyllis multidentata (Hartmann- Schröder, 1982) agree with the description of Eusyllis kupfferi, so we consider them as synonymous.</p> <p>Distribution. Portugal (Madeira), Canary Is., Cuba, Australia (Queensland, Western Australia, New South Wales).</p> <p>Habitat. Occurring on hydroids, Rhizophora mangle roots, on algae, algae with sand, debris, dead corals, sand and mud, from intertidal to about 20 m.</p> </div>	https://treatment.plazi.org/id/038287B3A212FFDFAAF022F5FE45F942	Public Domain	No known copyright restrictions apply.

Complete specimen 6.3 mm long, 0.5 mm wide, with 50 chaetigers. Prostomium semi-circular; 4 eyes in open trapezoidal arrangement and 2 anterior eyespots. Median antenna more than twice combined length of prostomium and palps, inserted on middle of prostomium, lateral antennae shorter than median antenna, inserted in front of anterior eyes, near anterior margin (Fig. 15A). Palps broad, similar in length to prostomium (Fig. 15A). Nuchal organs with distinct ciliation, extending to posterior margin of prostomium (Figs 15A, 16A). Peristomium similar to subsequent segments; dorsal tentacular cirri long and slender, more than twice as long as body width, ventral tentacular cirri about third length of dorsal cirri. Antennae, tentacular and dorsal cirri smooth, long, slender, distally tapered (Fig. 15A), sometimes rugose to weakly pseudoarticulate (Fig. 16B). Dorsal cirri of chaetiger 1 longer than dorsal tentacular cirri, remaining dorsal cirri irregularly alternating long, and short cirri, long cirri much longer than body width, and short ones, slightly shorter than body width (Fig. 15A). Ventral cirri of chaetiger 1 enlarged, flattened leaf-like; following ones conical (Figs 15B, 16B); ventral cirri with minute pores (Fig. 16D). Lateral tufts of cilia on each segment (Fig. 16C). Compound chaetae heterogomph, with subdistal spines on shafts and bidentate blades, both teeth similar in size, well separated and rounded margin between both teeth, and fine spines on margin (Figs. 15D,F,G, 16E,F). Anterior parapodia with about 20–25 compound chaetae, with strong dorsoventral gradation in size of blades within fascicle, about 40 µm in length dorsally, 21 µm in length ventrally. Progressively along body, number of compound chaetae per parapodium decreases, to 13–15 on midbody, 10 on posterior parapodia, with thicker shafts and blades, with less marked dorsoventral gradation in length of blades; on midbody, blades about 35 µm in length dorsally, 22 µm in length ventrally, and 30 µm in length dorsally, and 15 µm in length ventrally on posterior parapodia (Fig. 15D,F,G). Dorsal simple chaetae on posterior parapodia, slender, bidentate, both teeth similar, with short spines on margin (Fig. 15I). Ventral simple chaetae on far posterior parapodia, similar to dorsal simple chaetae, but larger and teeth well separated (Fig. 15J). Anterior parapodia with 2 aciculae, one distally knobbed with acute tip, other with tricuspid tip, with lateral ones poorly developed (Fig. 15E); medium and posterior parapodia each with single acicula, distinctly tricuspid (Fig. 15H). Pharynx through about 7 segments; pharyngeal tooth, conical, on anterior margin; trepan variable, ranging from few small teeth present to distinct incomplete crown of up to 24 teeth (Figs 15C, 16B).</p> <p>Remarks. This species is characterized by having enlarged, flattened leaf-like ventral cirri on chaetiger 1, tricuspid aciculae, and compound chaetae with bidentate blades, with both teeth of similar size and well separated by rounded margin. The Australian specimens were described as Eusyllis dentata by Hartmann-Schröder (1990); and these were examined and they are indistinguishable from Mediterranean specimens of Eusyllis lamelligera. This species has been reported from a wide range of habitats and depths and material should be re-examined and a molecular study would be useful to confirm if this is a widely distributed species or a suite of sibling species.</p> <p>Eusyllis habei Imajima, 1966, from Japan, is also similar according to the description and may represent the same species according to Imajima (1966). The material examined from Bos Peninsula, Japan appears to be similar to specimens of E. lamelligera from the Mediterranean and also to material from the Atlantic and Australia.</p> <p>Habitat. Occurring in a wide variety of substrates and depths, intertidally to depths greater than 500 m.</p></div> 	https://treatment.plazi.org/id/038287B3A214FFDDAA8822E7FD35FD92	Public Domain	No known copyright restrictions apply.

Dorsal cirri elongated, smooth, distally tapered, but sometimes short or indistinctly articulated. Parapodia usually with pre- and postchaetal lobes. Ventral cirri digitiform to pillow-shaped. Compound chaetae heterogomph, usually with shafts distally spinose. Dorsal and ventral simple chaetae present on some parapodia. Pharynx short, distinctly shorter than proventricle, provided with several teeth, usually few, pointing backwards, pharyngeal mid-dorsal tooth absent; pharynx when not everted situated posteriorly to chaetiger 1, inside tube that leads to mouth opening on peristomium. Proventricle usually long and wide, massive. Pygidium with 2 anal cirri. Reproduction by epigamy; epigamic specimens sometimes strongly modified and phosphorescent (Fischer &amp; Fischer, 1995; Gaston &amp; Hall, 2000).</p> <p>Remarks. The structure of the anterior part of the gut in this genus is distinct and unusual, with the pharynx being short and the opening located posteriorly to the mouth; a tube is present that surrounds the pharynx and that leads to the mouth. This must be removed to see the trepan and the two lateral plates of the pharynx. Occasionally specimens lack any teeth on the trepan, and we suggest that individuals can regenerate these teeth. The genera that we have synonymized with Odontosyllis have been inadequately examined previously with regard to the structure of the anterior part of the gut. For example, GSM examined one paratype of Pharyngeovalvata natalensis (BMNH 1961.16.16-17, Natal Shore, South Africa Stn. 47.8, coll: J.H. Day) and it is identical to specimens of Odontosyllis ctenostoma Claparède, 1868. Both species possess a pharynx with a trepan; even though the description of the pharynx of Pharyngeovalvata by Day (1951) states that the pharynx lacks a trepan, the paratype possesses one. We therefore have synonymized these two species that are the type species of their respective genera and Pharyngeovalvata is synonymized with Odontosyllis. We suspect that Atelesyllis Pruvot, 1930, is also identical to Odontosyllis with the pharynx contracted, but the types appear to be lost. We have also examined the holotype of Synpalposyllis australiensis Hartmann-Schröder, 1983 (HZM P-17400), a species known only from the holotype, which is less than 5 mm in length, with the prostomium and the anterior part of the pharynx damaged so it is not possible to verify the presence or absence of the palps, but the chaetae and aciculae are similar to those of O. australiensis. In our opinion, this specimen may be a juvenile of O. australiensis. Types of Alluaudella madagascariensis Gravier, 1905 were not available for examination but this species appears to be related to some species of Odontosyllis with short dorsal cirri and indistinct ventral cirri, distally located, and partially fused, appearing as absent, although this should be checked on material from the type locality. We have examined type material of the other species of the genus, Alluaudella longicirrata Mohammad, 1973, and it is clearly a species of Odontosyllis. We suggest that it is likely that the genus Alluaudella should be synonymized with Odontosyllis, and it certainly does not belong in the subfamily Autolytinae where it has previously been placed (Gravier, 1905).</p> <p>The key below includes nine species, an additional two species have been reported from Australia, but they are not included in the key. Odontosyllis hyalina Grube, 1878, was reported by Hartmann-Schröder (1990); and we have examined the specimen (HZM P-20185) and it is a small, probably a juvenile specimen, belonging to O. australiensis; the original description (Grube, 1878) is based on a single, epigamic specimen (MPUW, 325), in poor condition, but the compound chaetae are similar to those of O. australiensis but the shafts are proportionally larger, the blades are shorter, some of them almost unidentate. Haswell (1920) reported two specimens of Odontosyllis suteri Benham, 1915, from Port Jackson, Sydney, as the type description from New Zealand specimens is incomplete and no details of the chaetae are given it is therefore difficult to verify Haswell’s identification, and we suggest that they may represent individuals of Odontosyllis polycera. So neither of these records of O. hyalina and O. suteri from Australia are likely to be valid.</p> </div>	https://treatment.plazi.org/id/038287B3A219FFD3A9BF2588FC21FCDB	Public Domain	No known copyright restrictions apply.

All material collected Hartmann-Schröder.</p> <p>Description. Body long, slender, (Fig. 18A), about 4.8 mm long, 0.3 mm wide, with 47 chaetigers. Prostomium oval, laterally convex, with 2 lateral and 2 frontal tufts of cilia (Fig. 18A); 4 eyes in rectangular arrangement, those of anterior pair slightly larger than posterior ones; antennae short, digitiform, shorter than prostomium; median antenna inserted between anterior eyes; lateral antennae inserted near anterior margin, close to each other, near midline of margin (Fig. 18A). Palps shorter than prostomium, blunt. Peristomium shorter than subsequent segments; tentacular cirri similar to antennae; dorsal ones longer than ventral ones. Occipital flap absent, although some with peristomium ones, similar in shape and size to dorsal tentacular cirri. Ventral cirri fused with parapodial lobes, inserted distally (Fig. 18A,D). Parapodia each with 4 compound chaetae (Fig. 18D), strongly heterogomph, shafts with subdistal large tooth, and short, smooth, triangular, bidentate blades, subdistal tooth small, all similar in shape and length (Fig. 18E), 7–8 µm in length. Solitary ventral simple chaeta on far posterior parapodia of one specimen, slender, smooth, unidentate (Fig. 18G). Dorsal simple chaetae not observed. Solitary acicula on each parapodium, distally acuminate (Fig. 18F). Pygidium large, slightly bilobed, with 2 long, slender, filiform anal cirri (Fig. 18B). Pharynx through about 2 segments, according to original description, trepan with 6 small teeth (Fig. 18C); dark gland near pharynx opening (Fig. 18C). Proventricle long and slender, through about 7–8 segments (Fig. 18A), with about 50 muscle cell rows.</p> <p>Remarks. This species has small ventral cirri, inserted distally. Hartmann-Schröder (1979) made an incorrect interpretation of the parapodia, overlooked the ventral cirri and described it as a new genus, which she placed in the subfamily Autolytinae. Nygren (2004) synonymized Odontoautolytus with Odontosyllis. After examination of the type series of both species, Odontoautolytus annulatus and Odontosyllis brevicirra, we suggest that they represent the same species Odontosyllis annulatus.</p> <p>Habitat.

Prostomium small, hidden under most anterior segments (Figs 27C, 28A–C) (probably contracted), with 2 black lateral spots and posterior transverse band; antennae short and slender, inserted in front of anterior eyes, median antenna longer than lateral antennae, inserted slightly posteriorly (Figs 27C, 28B,C), similar to combined length of prostomium and palps. Prostomium with 2 slightly raised mounds with minute pores (see arrows Fig. 27D,E). Two densely ciliated, semi-circular nuchal organs (Fig. 27C,D). Palps small, fused basally, ventrally folded. Peristomium</p> <p>(G) long-bladed compound chaetae, midbody; (H) falcigers, midbody. Holotype</p> <p>AM W11110, except B, AM W202645. Scales: A–C,E: 0.8 mm, D: 0.2 mm, F:</p> <p>0.18 mm, G,H: 20 µm.</p> <p>small, dorsally nearly covered by small lobe of chaetiger 1 (Figs 27C, 28B); tentacular cirri similar to antennae, but slightly longer. Anterior dorsal cirri elongated, smooth, distally tapered, rugose to pseudoarticulate (Figs 27C, 28A) becoming progressively shorter along body (Figs 27F, 28D), slightly longer than parapodial lobes. Parapodia with 2–3 parallel lobes (Figs 27F, 28D, 29A). Ventral cirri short, pillow-shaped (Figs 27F, 28D). Compound chaetae numerous, shafts distally spinose, and blades of 2 kinds, most dorsal ones with elongate, bidentate blades (Fig. 28G), short spines on margin, and remaining chaetae with short, triangular, distinctly bidentate blades (Figs 28H, 29A–E); on midbody, parapodia with about 6–7 compound chaetae of slender type, 37–45 µm in length, and 28–30 chaetae with short blades, all similar, about 16–18 µm in length; compound chaetae slightly longer on anterior parapodia (Fig. 29A,B). Aciculae slender, distally blunt, numerous in anterior parapodia, reduced to 2–3 on posterior parapodia. Dorsal simple chaetae slender, thin, unidentate (Fig. 29C). Ventral simple chaetae on posterior parapodia, bidentate, with short spines on margin (Fig. 29C,F). Pharynx through 3–4 segments, with 5 teeth and 2 lateral plates (Fig. 28F). Proventricle long, slender (Fig. 28E), through 9 segments, with about 80 muscle cell rows.</p> <p>Remarks. The small lobe on the peristomium is not regarded as an occipital flap. This species is characterized by its colour pattern, a lack of an occipital flap, and two kinds of compound chaetae being present. Odontosyllis trilineata Imajima, 2003 has a similar colour pattern and chaetae, but they differ in that O. gravelyi also has long-bladed chaetae, and O. trilineata has a distinct occipital flap and 9 teeth on trepan (Imajima, 2003).</p> <p>Habitat. Occurring in coarse sand and gravel and mud, shallow depths often in estuarine conditions.</p> <p>Distribution.

Body broad, robust anteriorly, tapered posteriorly, 25 mm long, 2 mm wide, with 93 chaetigers. Distinctly coloured (Fig. 32A) with transverse black rows and other yellowish areas on preserved specimens; 2 kidneyshaped black spots on prostomium (Fig. 32B); chaetigers 1, 4, 6, 9 darkly pigmented, subsequent segments, consisting of one darkly pigmented segment followed by unpigmented segment, this striped pattern continues to mid body, following segments with reduced pigmentation; each segment slightly biannulate with dorsum rugose. Prostomium almost circular, totally covered by occipital flap (Figs 32A, 34A,B), with 4 eyes in rectangular pattern, antennae short and thick, shorter than prostomium, indistinctly wrinkled (Fig. 32B,C), originating close to each other, all similar size, median antenna originating slightly posteriorly to lateral antennae, all antennae covered by occipital flap. Palps triangular, ventrally folded (Fig. 32C). Peristomium dorsally reduced, covered by chaetiger 1 and occipital flap (Fig. 32A), forming 2 lobes ventrally (Fig. 32C). Occipital flap large (Figs 32A–C, 34A,B) colourless. Tentacular and dorsal cirri similar, short, thick, slightly with elongate, slender blades, distally bidentate and short spines on margin; remaining chaetae with shorter and wider blades that progressively along body, become strongly bidentate, with short spines on margin (Figs 33B,D, 34E, 23A,B). Anterior compound chaetae shorter and more slender than posterior ones, about 20 per parapodium, with dorsoventral gradation in length of blades within fascicle, 38 µm in length dorsally, 16 µm in length ventrally, those of posterior parapodia, numbering about 15 per parapodium, 46 µm in length dorsally, 26 µm in length ventrally. Dorsal and ventral simple chaetae not seen. Aciculae slender, distally broad, numerous on anterior parapodium, numbers decreasing posteriorly to 2–3 on posterior parapodia (Fig. 33C). Pharynx about half of length of proventricle (Fig. 33E), with 5 teeth and 2 lateral plates (Fig. 33F). Proventricle long and wide, with about 56 muscle cell rows (Fig. 33E).</p> <p>Remarks. Odontosyllis marombibooral n.sp. differs from all other species of the genus in having a large occipital flap, which covers totally the prostomium and antennae, a distinctive colour pattern, bifid parapodia with distal ventral cirri, and short, pseudoarticulated dorsal cirri. No other species has this combination of characters. The most similar species is Odontosyllis picta (Kinberg, 1865 described as Eurymedusa picta), from New Zealand (Ehlers, 1904) (also questionably reported for Australia), which also has a large occipital flap, but not as large as the one present in Odontosyllis marombibooral n.sp. Odontosyllis picta also has black transverse stripes, but they are arranged in a different pattern to those of Odontosyllis marombibooral, and the compound chaetae have all short blades, whereas Odontosyllis marombibooral, has two types of chaetae present. Odontosyllis rubrofasciata (Pruvot, 1930), from New Caledonia, (described as Atelesyllis rubrofasciata), and O. rubrofasciata Grube, 1878 (a possible homonym), have strikingly similar colour patterns, short dorsal cirri, and compound chaetae that resemble those present in Odontosyllis marombibooral, but the occipital flap is much smaller and this character easily separates these three species. Fauvel, in the notes given after the description of Atelesyllis rubrofasciata considered that is a different species to O. rubrofasciata Grube, 1879. Odontosyllis rubrofasciata (Pruvot, 1930) has transverse stripes, but only from the midbody onwards, the prostomium has 4 lobes. The chaetae, although similar to those of O. marombibooral are slightly different, with long blades not as elongated and short blades with distal tooth not as curved as those present in O. marombibooral. In the description of Atelesyllis rubrofasciata (Pruvot, 1930), pharyngeal teeth are not mentioned as being present, although examining a range of species of Odontosyllis some individuals appear to lack these teeth. In all other characters, however, they are identical to specimens with teeth, suggesting they may lose these teeth and be able to regenerate them.</p> <p>Habitat. Occurring in dead corals and sponges, from depths of 1– 12 m.</p> <p>Distribution. Australia (Western Australia).</p> <p>Etymology. The name of this species comes from two aboriginal words, marombi, meaning shield, and booral, meaning big, or large, in reference to the large occipital flap present.</p></div> 	https://treatment.plazi.org/id/038287B3A229FFE3AB0F2036FEB2F928	Public Domain	No known copyright restrictions apply.

Peristomium similar in length to following segments; dorsal tentacular cirri long, filiform, longer than median antenna, ventral tentacular cirri about one third length of dorsal cirri. Dorsal cirri, as well as antennae and tentacular cirri, smooth, filiform, alternating irregularly, long cirri, longer than body width, and short cirri, shorter than body width (Fig. 37A). Parapodial lobes rectangular, ending with pre-chaetal lobe. Ventral cirri large, triangular, partially fused to parapodial lobes on anterior parapodia, with some granular inclusions, becoming digitiform, not fused to parapodial lobes, on subsequent segments. Compound chaetae compound heterogomph, shafts distally spinose, and two kinds of blades, long, spiniger-like chaetae, anteriorly bifid (Fig. 37B), apparently unidentate on posterior parapodia (Fig. 37D), and bidentate falcigers, elongate, with short spines on margin and margins of blades weakly convex on anterior parapodia, bidentate, with unequal teeth, proximal tooth longer and broader than distal tooth (Fig. 37C), becoming more marked on posterior chaetae (Fig. 37E). Anterior parapodia with about 3 spiniger-like chaetae, blades 90–175 µm in length; and about 50 falcigers with blades 25–27 µm in length; progressively posteriorly number of compound chaetae decreasing to 1–2 spinigerlike, about 105 µm in length, smooth and unidentate, and 25 falcigers, 25–22 µm in length, on mid-posterior parapodia. Simple dorsal and ventral chaetae not seen. Aciculae distally slightly enlarged, ending in button, 4 on most anterior parapodia (Fig. 37F), reducing to 2 on midposterior parapodia, one large and other slender (Fig. 37G). Pharynx long and slender, through about 11 segments; pharyngeal tooth long and large, oval, located slightly anteriorly to middle of pharynx (Fig. 37A). Proventricle large, through about 6 segments, with 23 muscle cell rows. Details of posterior end unknown.</p> <p>Remarks. Opisthodontha hanneloreae n.sp. is similar to O. melaenonephra, but lacks any colour pattern, the spiniger-like chaetae are distinctly longer and more slender, unidentate from midbody onwards. Opisthodonta morena Langerhans, 1879 (see above), and O. mitchelli Kudenov &amp; Harris (1995) have much shorter spiniger-like chaetae than O. hanneloreae.</p> <p>Habitat. Occurring in dead corals and in shell debris, in shallow water.</p> <p>Distribution. Australia (Western Australia).</p> <p>Etymology.

Opisthosyllis brevicirra Hartmann-Schröder, 1979, designated by Hartmann-Schröder, 1991.</p> <p>Diagnosis. Body robust, cylindrical, broad anteriorly, tapered posteriorly, with many segments. Dorsal and ventral surfaces covered with numerous, small papillae. Prostomium with 4 lensed eyes and 3 antennae. Palps broad, fused at base, ventrally folded. Peristomium shorter than subsequent segments, sometimes covered dorsally by chaetiger 1; 2 pairs of tentacular cirri. Nuchal organs as 2 ciliated grooves between prostomium and peristomium. Dorsal and ventral cirri on all chaetigerous segments. Antennae, tentacular, anal and dorsal cirri smooth, enlarged, club-shaped to foliaceous. Dorsal cirri usually provided with distinct cirrophores; on some species, dorsal cirri of anterior segments alternating in size between large and small ones, larger cirri arising more dorsally. Parapodia with compound, heterogomph chaetae, and dorsal and ventral simple chaetae on posterior parapodia. Pharynx wide, with pharyngeal tooth inserted far from anterior rim. Proventricle wide, voluminous. Pygidium small, with 2 anal cirri.</p> <p>Remarks. According to Hartmann-Schröder (1991), this genus belongs to the Eusyllinae. It has some unusual morphological characters, however, such as the shape and arrangement of dorsal cirri, epidermal papillae, shape of pharynx and proventricle; its method of reproduction is unknown. It appears to be closely related to Rhopalosyllis, and therefore should be considered as a member of the subfamily Syllinae. Until its method of reproduction is determined, we are retaining it within the Eusyllinae according to its original designation.

Body anteriorly broad, tapered posteriorly (Fig. 52A), 6.7 mm long, 0.5 mm wide, with 59 chaetigers. Dark area of pigment dorsally on each segment, sometimes divided into 2 dorsal areas, anterior and posterior lateral areas; dark areas forming incomplete transverse row on posterior segments (Fig. 50A–C). Small, scattered papillae on lateral and ventral surfaces, more numerous on dorsum (Figs 50A,C, 52C,D). Prostomium oval, 4 small eyes arranged in open trapezoidal pattern, almost in straight line; lateral antennae inserted near anterior margin, oval, slightly rugose, shorter than combined length of prostomium and palps, median antenna similar to lateral but thicker, slightly longer, provided with dark inclusions, inserted slightly posteriorly to lateral ones, in front of eyes (Fig. 50A). Palps broad, longer than prostomium, ventrally folded (Figs 50D,E, 52C). Peristomium shorter than subsequent segments; tentacular cirri similar in shape to lateral antennae, but larger. Dorsal cirri of chaetiger 1 distally inflated, club-shaped, provided with dark inclusions, and located laterodorsally, anteriorly directed, partially covering prostomium (Fig. 50A,C,D); dorsal cirri of chaetigers 4 and 6 similar, but less inflated and more laterally inserted, subsequent dorsal cirri club-shaped, not as inflated as those of chaetigers 1, 4 and 6, without dark inclusions; alternating dorsal cirri laterodorsally located and others slightly smaller, more laterally located, cirri becoming smaller posteriorly (Fig. 50C,D). Dorsal cirri with cirrophores. Anterior parapodia with 7 compound, heterogomph chaetae, shafts with some spines on distal margin, and curved blades; 2 dorsalmost compound chaetae with relatively short, bidentate blades, with both teeth close to each other, and short spines on margin (Fig. 51C), 16 µm long; remaining compound chaetae with smooth, unidentate blades (Figs 51C, 52G), within fascicle slight dorsoventral gradation in length of blade, 22 µm in length dorsally, 17 µm in length ventrally. Progressively along body, chaetal blades becoming shorter and less bidentate; posterior parapodia with 6 compound chaetae, decreasing to 3 on posteriormost chaetigers, blades slightly hooked, smooth on margin, unidentate (Figs 51G, 52H), blades 15 µm in length dorsally, 10 µm in length ventrally. Dorsal simple chaetae slender, unidentate, smooth (Fig. 51F), present on posterior chaetigers (Fig. 52I). Ventral simple chaetae smooth, distally bent, unidentate, present on most posterior parapodia (Figs 51H, 52I). Anterior parapodia with 3–4 aciculae, distally rounded, single acicula on posterior parapodia (Fig. 51E). Pharynx wide, through 3–4 segments; pharyngeal tooth located about one third from anterior margin of pharynx (Fig. 51A). Margin of pharynx with 10 papillae (Figs 51A, 52E), each papilla with short cilia (Fig. 52F). Proventricle, longer than pharynx, extending through 3 segments, with 25–30 muscle cell rows. Pygidium small, with 2 anal cirri with dark inclusions, inflated and oval (Fig. 50B).</p> <p>Remarks. This species is similar to P. brevicirra Hartmann- Schröder, 1979 (see below) but P. alternocirra has short and long dorsal cirri alternating along the anterior part of the body, distinct dark inclusions on the median antenna and large dorsal cirri, a colour pattern, and some dorsal compound chaetae on anterior and midbody parapodia with bidentate blades. In contrast, P. brevicirra has only unidentate chaetae, dorsal cirri not as inflated and lacks dark inclusions on the antennae and cirri, and is colourless. The specimen reported as Opisthosyllis brevicirra by Hartmann- Schröder (1982) belongs to this new species and differs from the holotype of the taxon.</p> <p>Habitat. Occurring in algae, seagrasses, and sponges; from intertidal to shallow depths.</p> <p>Distribution. Australia (Western Australia).</p> <p>Etymology. The specific name refers to the alternating sizes of the dorsal cirri along the body.</p></div> 	https://treatment.plazi.org/id/038287B3A23DFFF4AB00272BFDBDF83D	Public Domain	No known copyright restrictions apply.

Prostomium oval, with 4 eyes arranged in open trapezoidal pattern (Fig. 68A). Median antenna long, coiled on holotype, several times longer than combined length of prostomium and palps, inserted between posterior eyes; lateral antennae distinctly shorter than median antenna, inserted near anterior margin of prostomium (Figs 68A, 69A–C). Palps broad, similar in length to prostomium or slightly longer.Tentacular and dorsal cirri long, smooth, coiled on holotype, long on anterior segments, becoming shorter on segments beyond proventricle, alternating long cirri (Figs 68C, 69A,B), 2–3 times as long as body width, and short cirri (Fig. 68B), slightly shorter than body width; dorsal cirri with cirrophores. Ciliary bands on dorsum of each segment and areas of dorsal cirri (Fig. 68B–D), distinct on holotype (Fig. 68A); anterior segments with single ciliary band (Fig. 69B,C), double from proventricle segments posteriorly (Fig. 69D). Parapodial lobes conical, ending with 2 lobes (Fig. 68B,D). Ventral cirri digitiform, shorter than parapodial lobes anteriorly, becoming longer posteriorly (Fig. 68B,D).Anterior parapodia with about 10–14 compound chaetae, slightly enlarged, distally truncated shafts, provided with short subdistal spines, and bidentate blades, both teeth similar, with long spines on margin, pointing distally, those of basal part coarse, distal ones thin, reaching or extending beyond proximal tooth, 1–3 slightly longer (Fig. 68E), rest of chaetae within fascicle with slight dorsoventral gradation in length (Fig. 68F), 26 µm in length dorsally, 18 µm in length ventrally. Posteriorly, number of compound chaetae per parapodium decreasing, and blades of 1–3 most dorsal compound chaetae becoming proportionally longer (Figs 68H, 69F) and rest with dorsoventral gradation in length (Figs 68I, 69E); midbody parapodia with 1–2 compound chaetae with relatively long blades, about 31 µm in length, and 4 compound chaetae 15–25 µm in length; proximal tooth proportionally longer than those of anterior chaetae (Fig. 62A). Posterior parapodia with 1 compound chaeta with long blades (Fig. 68K), 33 µm long, and 3 compound chaetae, similar to those of midbody, but with distinctly larger proximal tooth (Figs 68L, 62C), well separated from distal tooth, 18–22 µm in length. Dorsal simple chaetae from midbody, distally bifid to truncate (Figs 68G, 62B), thicker posteriorly, with short, coarse spines on margin (Fig. 68 O). Ventral simple chaetae on posterior parapodia, sigmoid, thick, strongly bidentate, both teeth well separated, almost at 90°, proximal tooth long, broad, slightly hooked, with few, long subdistal spines, surpassing level of proximal tooth (Figs 68P, 62C).

Pharynx through about 6 segments, pharyngeal tooth located on anterior rim. Proventricle through 4 segments, with about 26 muscle cell rows. Pygidium small, with 2 anal cirri.</p> <p>Remarks. Pionosyllis koolalya is similar to P. serrata described above but differs mainly in lacking enlarged anterior parapodia with thick compound chaetae with markedly short blades; remaining compound chaetae are rather similar, but the dorsal simple chaeta of P. koolalya is truncated, and slightly bifid in P. serrata. All other species of the genus are provided with long, spiniger-like chaetae. These two species also have fewer compound chaetae with distinctly longer blades than other chaetae in the fascicle, but they are relatively short and less than half the length of the longest bladed chaetae.

Body fragile, dorsally arched, cylindrical, without colour pattern, yellowish in alcohol. Prostomium oval, with 4 eyes in open trapezoidal arrangement. Antennae damaged; lateral antennae inserted near anterior margin of prostomium, median antenna inserted on middle of prostomium. Palps large, slightly longer than prostomium, free from each other (Fig. 74A). Nuchal organs ciliated, extending to lateral margins of prostomium (Fig. 74A). Peristomium dorsally reduced, covered by chaetiger 1. Anteriormost segments short, becoming longer from proventricle onwards. Left dorsal tentacular cirrus missing, right one appears broken; ventral tentacular cirri shorter than dorsal cirri. Dorsal cirri smooth, with distinct cirrophores, elongated, alternating irregularly long and short (Fig. 74A), long cirri similar in length to body width, shorter cirri less than half length of longer ones. Parapodial lobes conical. Ventral cirri elongated, similar in length to parapodial lobes. Compound chaetae heterogomph, blades of two kinds, spiniger-like and falcigers. Midbody parapodia with 2 spiniger-like chaetae, with short spines on margin, distinctly bidentate, distal tooth hooked, and proximal tooth curved, with tendon contacting with margin, about 40–35 µm long (Fig. 74C), and 8–11 falcigers, strongly bidentate, long and hooked distal tooth and long, curved proximal tooth, provided with distinct tendon contacting with edge of blade, slight dorsoventral gradation in length of blades within fascicle, 25 µm dorsally and 15 µm ventrally (Fig. 74D), with thin spines on margin. Anteriormost parapodia with 1–2 distinctly long, slender, spiniger-like chaetae present, blades about 86 µm in length, bidentate, with both blades similar in size, proximal tooth slightly recurved, but without tendon (Fig. 74B). Dorsal and ventral simple chaetae not seen. Aciculae tricuspid, 3 on anterior parapodia (Fig. 74E), 2 on midbody parapodia (Fig. 74F). Pharynx wide, though about 7–8 segments; pharyngeal tooth conical, located in front of middle of pharynx (Fig. 74A). Proventricle through 7 segments, similar in size to pharynx, with about 28 muscle cell rows.</p> <p>Remarks. Pionosyllis rousei n.sp. is characterized by having compound chaetae distinctly bidentate, with both teeth similar and well separated from each other. Pionosyllis serratisetosa (López, San Martín &amp; Jiménez, 1997), from southwestern Mediterranean has similar chaetae, but the teeth on the blades are not separated and are smaller, the blades have a different shape; long spiniger-like compound chaetae are absent, and the pharyngeal tooth is located near anterior margin of pharynx. Pionosyllis longocirrata (Saint- Joseph, 1887), from the eastern Atlantic and Mediterranean Sea, also has the pharyngeal tooth located more anteriorly than P. rousei, and the blades of compound chaetae either have a minute distal tooth or none (see San Martín, 2003, for more details). Pionosyllis templadoi (San Martín, 1991) from Cuba has a similar body and the position of pharyngeal tooth is also similar. The blades of compound chaetae, however, have a small distal tooth and an elongated proximal tooth (San Martín, 1991). Pionosyllis luquei (San Martín, 1990), also from Cuba, has similar compound chaetae, although not as strongly hooked, with well-developed teeth, but the dorsal cirri are shorter, and the pharyngeal tooth is located more posteriorly (San Martín, 1990).</p> <p>Habitat.

Proventricle about half of pharynx length, with about 20 muscle cell rows. Details of posterior segments unknown. Remarks. Pionosyllis yolandae n.sp. is similar to Pionosyllis aciculata San Martín, 1990, from Cuba; but, this latter species has much shorter compound chaetae, with typical dorsoventral gradation in length of blades within a fascicle, and lacks elongated, spiniger-like compound chaetae (San Martín, 1990). Pionosyllis lamelligera (Saint- Joseph, 1887) has spiniger-like chaetae, but it lacks the characteristic enlarged, tridentate aciculae, and the posterior falcigers have the proximal tooth longer than distal tooth present, whereas in Pionosyllis yolandae the teeth are of similar size (San Martín, 2003, for a description of Pionosyllis lamelligera).</p> <p>Habitat. Occurring on gorgonaceans, ascidians, sponges, and in sand, from 14 to 244 m depths.</p> <p>Distribution. Australia (New South Wales, Western Australia).</p> <p>Etymology.

Opisthodonta pterochaeta Southern, 1914, herein designated.</p> <p>Diagnosis. Body long, slender, tapered anteriorly and posteriorly, with numerous segments. Prostomium pentagonal to triangular, with 4 eyes and 2 anterior eyespots. Three antennae. Palps short, fused basally, triangular in shape. Nuchal organs as 2 ciliated grooves between peristomium and prostomium. Two pairs of tentacular cirri. Antennae, tentacular and dorsal cirri elongated, smooth, distally tapered. Ventral cirri triangular. Compound chaetae with translucent hood on margin, ornamented with several rows of minute spines. Dorsal simple chaetae with translucent hood. Ventral simple chaetae probably absent. Aciculae of several anterior parapodia distinctly enlarged. Pharynx and proventricle long, pharyngeal tooth located laterally and distinctly posteriorly, close to proventricle. Reproduction by epigamy.</p> <p>Remarks. The species Opisthodonta pterochaeta differs in several characters from the emended diagnosis of Opisthodonta, such as having palps fused basally, pharyngeal tooth located laterally, extremely long pharynx and proventricle, and, also having enlarged aciculae on several anterior segments and with different types of chaetae. As suggested by Kudenov &amp; Harris (1995), a new genus was needed for this species.</p> <p>Streptodonta n.gen., is similar to Streptosyllis in having enlarged aciculae on some anterior parapodia, but differs in having a pharyngeal tooth, much longer pharynx and proventricle, and in the shape of the compound chaetae.</p> <p>It is probably more closely related to Psammosyllis Westheide, 1990, than to Opisthodonta, sharing with the former some unusual characters, such as the position of the pharyngeal tooth (see Westheide, 1990).</p> <p>Etymology. The name of the new genus is a combination of the prefix streptos, from the Greek, meaning twisted, (in reference to Streptosyllis), and the suffix donta, (in reference to Opisthodonta), because it shares characters of both genera, thick, enlarged aciculae, like those present in Streptosyllis and a posterior pharyngeal tooth, like those present in Opisthodonta.</p> </div>	https://treatment.plazi.org/id/038287B3A261FFAAA9F12498FBE0FA4D	Public Domain	No known copyright restrictions apply.

Up to 4.9 mm long for 36 chaetigers (mature specimen), but usually smaller; examined specimens up to 1.4 mm long, 0.2 mm wide, with 23 chaetigers; fragile, often broken and damaged. Prostomium oval, with 4 eyes arranged in an open trapezoidal pattern and 2 anterior eyespots (Fig. 82A). Antennae smooth, club-shaped, similar in length to prostomium or longer, median antenna inserted between anterior eyes, lateral antennae inserted near eyespots. Palps reduced to 2 small, sometimes indistinct papillae (Figs 82A, 83B). Peristomium shorter than subsequent segments; tentacular cirri similar to antennae, dorsal ones slightly longer than ventral tentacular cirri. Dorsal cirri similar in shape and size to antennae (Fig. 82A) with distinct cirrophores. Parapodial lobes elongated, subrectangular, ending as rounded lobe (Fig. 82B), those of chaetigers 2–6 enlarged and truncated distally. Ventral cirri digitiform, elongated, longer than parapodial lobes, arising from about middle of ventral side of parapodial lobes (Figs 82B, 83A). Compound chaetae with homogomph articulations on anterior parapodia (Figs 82C,D, 83D), and hemigomph on mid to posterior parapodia (Figs 82F, 83C), provided with distinct subdistal spine on shafts, and bidentate blades, with short spines on margin. Anterior parapodia with 2 compound chaetae with elongate blades, about 21 µm long, distinctly bidentate, both teeth well separated (Figs 82C, 83D), and 6 compound chaetae with shorter blades (Fig. 82D), within fascicle blades 10 µm in length dorsally, 6 µm in length ventrally; difference between 2 types of chaetae becoming progressively less marked along body; posterior parapodia with 6 compound chaetae (Fig. 82F), bidentate with short spines on margin, dorsoventral gradation in length of blades within fascicle, 25 µm long dorsally, 9 µm long ventrally. Dorsal simple chaetae from chaetiger 1, unidentate, with minute serration on margin and distinct concave, translucent hood, covering tip of chaetae, small on simple chaetae of anterior parapodia (Figs 82E, 83E) but becoming more developed posteriorly (Figs 82G,H, 83F). Aciculae knobbed at tips, enlarged on chaetigers 2–6 (Fig. 82I). Pharynx extending through 3–4 segments, with crown of 10 soft papillae on margin (Fig. 83A). Proventricle large, pyriform, extending through about 6 segments and 40–48 indistinct muscle cell rows. Pygidium small, with 2 anal cirri and median papilla.</p> <p>Remarks. All Australian specimens have all dorsal cirri smooth; those from the Seychelles (Böggemann et al., 2003) have longer dorsal cirri, articulated, with two glands on each article, except anteriormost, which are smooth. Until more material is available, it is unknown as to the levels of variation of articulation of dorsal cirri that may occur within a species. So at this stage we are tentatively accepting the records of this species from the Seychelles.</p> <p>Habitat. Occurring interstitially in coralline sand, fine sand, mud, on algae, from intertidal to shallow depths.</p> <p>Distribution. Australia (Western Australia, South Australia, Tasmania, New South Wales), possibly Seychelles Islands.</p></div> 	https://treatment.plazi.org/id/038287B3A263FFA8AAAB278CFA09F83D	Public Domain	No known copyright restrictions apply.

R.T. Springthorpe, 2 Jan 1984, 2 (AM W26781).</p> <p>Description. Body less than 5 mm in length, densely covered with golden inclusions on dorsum of each segment and prostomium (Fig. 87A). Prostomium oval, about twice as wide as long; 4 small eyes in open trapezoidal arrangement; antennae missing on most specimens, short, smooth. Palps broad, fused at bases, shorter than prostomium, each ending with distal, small papilla (Figs 86C,D, 87A). Tentacular and dorsal cirri mostly missing. Parapodia elongated, ventral cirri digitiform. Compound chaetae with elongated, distinctly bidentate blades, arranged in 5 pairs of chaetae within fascicle, each pair of similar shape and length; blades of dorsalmost pair with long blades, about 55 µm long, with basal long spur (Figs 86F, 87D) and short spines on margin; blades of subsequent pair similar (Fig. 87E) but shorter, about 44 µm long; remaining compound chaetae similar in shape, lacking basal spur (Fig. 87E), with dorsoventral gradation in length of blades, 35 µm in length dorsally and 22 µm in length ventrally. Dorsal simple chaetae from chaetiger 1, thin, pointed (Figs 86E, 87B), with short spines on margin (Fig. 87B). Ventral simple chaetae absent. Aciculae slender, distally knobbed (Fig. 87C) pharynx everted on most specimens, through about 4 segments when relaxed. Proventricle long, through 7 segments (Fig. 87A), with about 47 muscle cell rows.</p> <p>Remarks. The original description of the species from Japan and descriptions of Mediterranean specimens do not describe the terminal papillae on the palps; these structures are small and could easily be overlooked. This species is characterized by having basal spurs on the bases of blades of the dorsalmost and second pair of compound chaetae; palps each with a small papilla on the Australian material, and dorsal simple chaetae, slender. Syllides caribica Licher, 1996, from Aruba Island in the Caribbean is similar, but differs in the following characters: the spurs on the compound chaetae are shorter, and have a smooth area between the spur and the edge of blade, the proventricle is shorter (through 2 segments), and the dorsal simple chaetae are slightly thicker (see Licher, 1996). Syllides floridanus Perkins, 1981 also has papillae on the palps, a long proventricle and slender, distally pointed dorsal simple chaetae; but the blades of the dorsalmost pair of compound chaetae lack basal spurs; they are present only on the second pair (Perkins, 1981).</p> <p>All the material examined from Australia is damaged and while it closely resembles material examined from the Mediterranean, it may represent an undescribed species, but complete specimens are needed in order to confirm this.</p> <p>Habitat. Occurring in sand, sandy mud, rhizomes of Posidonia, on algae and sponges; in shallow depths.</p> <p>Distribution. Japan, Western Mediterranean, USA (Massachusetts), Australia (New South Wales, Tasmania, Western Australia).</p></div> 	https://treatment.plazi.org/id/038287B3A266FFA2AAE42252FBA5FACB	Public Domain	No known copyright restrictions apply.

Body 2.4 mm long, 0.2 mm wide, with 30 chaetigers, dorsum with bright, minute inclusions, density of inclusions varies between individuals, fragile, most appendages missing on all specimens. Prostomium oval, with 4 eyes arranged in open trapezoidal pattern, and 2 anterior eyespots; 3 antennae all similar. Palps basally fused, shorter than prostomium (Fig. 88A). Peristomium with hyaline inclusions, larger than inclusions on dorsum; tentacular cirri elongated, slightly club-shaped, longer than lateral antennae (Fig. 88A), ventral tentacular cirri about two thirds length of dorsal cirri. Dorsal cirri of chaetigers 1, 2, elongated, longer than tentacular cirri, similar in length to body width; from chaetiger 3 onwards, dorsal cirri articulated (Fig. 88A), with about 10 articles (up to 16, fide Hartmann-Schröder), cirri mostly broken, articles usually with 1–2 dark, granular inclusions. Parapodia trapezoidal dorsally, slightly larger on anterior parapodia, becoming conical and slender from mid parapodia onwards. Ventral cirri digitiform, similar in length or shorter than parapodial lobes. About 15 compound chaetae on anterior parapodia, numbers diminishing progressively along body to about 10; shafts with thin subdistal spines; blades elongated, bidentate, with short spines on margin, without basal spurs (Fig. 88D– F), with dorsoventral gradation in length of blades within fascicle, about 50 µm in length dorsally, 20 µm in length ventrally, on midbody. Dorsal simple chaetae from chaetiger 1, distally blunt, with small distal hood and short spines on margin (Fig. 88B). Ventral simple chaetae absent. All parapodia with single acicula, distally knobbed, with filiform, short tip (Fig. 88C). Pharynx through 4 segments. Proventricle through 4 segments (Fig. 88A), with 24–30 muscle cell rows.</p> <p>Remarks. Syllides articulosus Ehlers, 1897, from Magellan Strait, in South America, appears to be a different species to the Australian specimens that were described by Hartmann-Schröder (1983) as a subspecies Syllides articulosus pumilus. Syllides articulosus has a proventricle distinctly longer than the pharynx (see Ehlers, 1897, pl. II, Habitat. Occurring on sponges, algae, Posidonia, and in sediments, from intertidal to shallow depths.</p> <p>Distribution.

G. Hartmann-Schröder, 1 (HZM P-16907).</p> <p>Description. Body 2.2 mm long, 0.3 wide mm with 30 chaetigers. Dorsal cirri long, with hyaline vacuoles on most articles (Fig. 89A). Tufts of cilia in front of each anterior eyespot. Ciliary bands on dorsum of each segment (Fig. 89A). Parapodia with about 5 compound chaetae, relatively long blades, bidentate, both teeth distinctly separated, with short spines on margin; blades of 2 medium length Remarks. The long, basal spurs on medium-length blades of compound chaetae have not previously been described. This character is considered to be a useful character to distinguish between species in this genus. Syllides bansei Perkins, 1981, has similar compound chaetae, but the dorsal simple chaetae differ in having a distal hood (Perkins, 1981). Syllides edentatus Westheide, 1974, also has a similar arrangement of chaetae, but the pair of the medium size chaetae have several long spines instead of a single basal spur as occurs in Syllides spinosus (Westheide, 1974; San Martín, 2003). Syllides benedicti Banse, 1972, also has a single long basal spur on the pair of medium-length bladed chaetae, but the dorsal simple chaetae are distally rounded, with some spines present in addition to the spines on margin (Banse, 1972). For a discussion of the differences between the stem species S. articulosus and S. spinosus see Hartmann-Schröder, 1979; furthermore, S. articulosus lacks long basal spurs on any blade (Somaschini &amp; San Martín, 1997).</p> <p>Habitat. Occurring in coarse and medium sand, on encrustations, from intertidal to shallow depths.</p> <p>Distribution.

Prostomium oval, slightly wider than long; 4 eyes arranged in open trapezoidal pattern and 2 anterior eyespots; median antenna inserted between posterior eyes, about one and half times combined length of prostomium and palps, lateral antennae about two thirds of length of median antenna, inserted near anterior eyes (Fig. 90A). Palps similar in length to prostomium, without distal papillae. Peristomium slightly shorter than subsequent segments, with hyaline, rounded inclusions; dorsal tentacular cirri similar to median antenna, slightly shorter; ventral tentacular cirri about two thirds length of dorsal ones (Fig. 90A). Antennae, tentacular, and dorsal cirri of chaetigers 1 and 2, elongate, slender; dorsal cirri of chaetiger 1 longer than median antenna, those of chaetiger 2 shorter than those of chaetiger 1, similar in length to median antenna. Dorsal cirri of subsequent segments alternating irregularly with long cirri, distinctly longer than body width, with about 10–12 articles; short cirri, similar in length to body width, with about 6–7 articles; articles pyriform, usually with 1 dark inclusion (Fig. 90A). Parapodial lobes elongated, conical, distally bilobed (Fig. 90C). Ventral cirri digitiform, similar in length to parapodial lobes. Compound chaetae similar throughout, shafts with several, long, fine, subdistal spines, and elongated, bidentate blades, within fascicle 5 pairs of chaetae, each pair similar in shape and length (Fig. 90D– G). Blades of most dorsal pair of compound chaetae with single long, distinct basal spur, and moderate, thin spines on margin, about 60–62 µm long; blades of second pair similar to those of most dorsal pair, but shorter, about 52 µm long, with shorter spines on margin (Figs 90D, 86A). Blades of subsequent pairs without basal spur and having short spines on margin (Fig. 90E–G), 40, 27 and 15 µm in length respectively. Dorsal simple chaetae from chaetiger 1, unidentate, distally blunt, provided with distal hood and short spines on margin (under light microscope) (Fig. 90H); under SEM, hood consists of several rows of minute spines (Fig. 86B). Ventral simple chaetae absent. Acicula solitary, distally knobbed (Fig. 90I). Pharynx through 5–6 segments (Fig. 83A). Proventricle barrel-shaped, through about 5–6 segments, with 35 muscle cell rows. Pygidium small, semicircular, with 2 short, smooth lateral anal cirri and 1 median, longer cirrus (Fig. 90B).</p> <p>Remarks. This species has been reported in Australia as Syllides longocirrata (Örsted, 1845), which only occurs in the Northern Atlantic and Northern Pacific areas, and differs from the Australian specimens, which are described as a new species. Syllides longocirrata has dorsal simple chaetae that are pointed and without a hood, and the compound chaetae are unidentate (see Banse, 1972), whereas the compound chaetae of Syllides tam are distally blunt and hooded. Syllides japonicus Imajima, 1966 (see below) and S. floridanus Perkins, 1981, also have dorsal simple chaetae that are pointed, and without a hood (Perkins, 1981), which differ from those present in Syllides tam.</p> <p>Habitat. Occurring in coarse, medium to muddy sand; from intertidal to 60 m.</p> <p>Distribution. Australia (Queensland, New South Wales, Victoria).</p> <p>Etymology. The species is named after The Australian Museum.</p></div> 	https://treatment.plazi.org/id/038287B3A26BFFA6AE0F214AFC1FFEF2	Public Domain	No known copyright restrictions apply.
