03F587FCA866FFBE40ECA27D5E7A46B9.taxon	materials_examined	Material examined HOLOTYPE: Australia, Queensland, Coolangatta, Rainbow Beach, lower intertidal in ne sand (July 1993), whole mount (lactophenol) (G 21182 2). Etymology The species is dedicated to Lester R. G. Cannon (Brisbane Museum), in recognition of his eOEorts to promote knowledge of Australian Platyhelminthes. Description The holotype is an adult worm, colourless, about 2 mm long in xed condition. With two pigmented eye-spots, enclosed within the brain capsule. The pharynx, short and collar-shaped, is located in the posterior fth of the body. Male genital organs. About 60 testes arranged in two irregular rows between vitellaria in front of the pharynx. The copulatory organ consists of two partly fused seminal vesicles, and an elongate muscular bulb (about 90 Mm long), provided with a copulatory stylet. The long seminal vesicles enter the bulb proximally. They are fused caudally for about one-third of their length. The spermiducts enter the seminal vesicles anteriorly. The stylet is a funnel-shaped structure, with a broad, oblique proximal opening and a narrow distal opening. The stylet is 38 Mm long. Its elongate base is about 25 Mm long, with a maximum width of 11 Mm. Ventrally, the stylet is provided with a narrow apophysis (about 15 Mm long). The apophysis is inserted at an angle of about 45 ss with the main axis of the stylet. Both in living and xed conditions, it appeared angled in its distalmost part (gure 8 D). Numerous, thick longitudinal muscles, most of which are connected basally with the musculature surrounding the bulb, are attached to the apophysis. The distal end of the stylet narrows above the apophysis into a slightly recurved tube, about one-third of the total length of the stylet. It is provided with a short tip (about 12 Mm long), where the narrow distal opening is located. The distal tip is perpendicular to the main axis of the stylet, and ends in a short, slightly curved terminal spike. Female genital organs. With two oocytes, arranged in a median row in front of the pharynx. Vitellaria stretch from behind the brain to in front of the ovaries; and from behind the pharynx to the level of the copulatory bulb. The oviducts fuse behind the bulb into a short common female duct, which opens to the outside through a female pore, medially between the seminal vesicles. Discussion The stylet of the new species, distinctly claw-shaped, with a short distal tip, and a comparatively long, oblique apophysis, is similar to that of the N. coelogynoporoide s species group (which includes N. coelogynoporoide s Meixner, 1938, N. ciliovesiculae Tajika, 1979 and N. riegeri Curini-Galletti and Martens, 1992) (cf. Curini-Galletti and Martens, 1992). However, no other Nematoplana has an apophysis which is angled distally. Furthermore, among the N. coelogynoporoide s group, the smallest stylet (that of the Mediterranean N. riegeri, which is about 60 Mm long) is still distinctly larger, with a slender base, and a proportionally longer portion of the stylet above the apophysis than that of N. cannoni. The Indo-Paci c member of the group (the Japanese N. ciliovesiculae) has a stylet somewhat similar in general shape to that of the new species, but markedly larger (about 130 Mm long), and with a relatively short, obtuse, straight apophysis. Members of the species group are furthermore much larger at maturity (> 10 mm), and have two rows of two to four isolated oocytes in front of the pharynx. The stylet of N. cannoni is somewhat similar in size and overall shape to that of N. nigrocapitula Ax and Ax, 1974, from Galapagos Is., which, however, has a shorter apophysis, not angled, a broader and straighter distal part, and a longer, straight terminal spike. Nematoplana nigrocapitula is furthermore distinct for its cephalic pigmentation, and for the presence of cnidosacs, cephalic gut and chorda intestinalis (Ax and Ax, 1974).	en	Curini-Galletti, M., Oggiano, G., Casu, M.

03F587FCA860FFBC40EBA7A95C89432D.taxon	materials_examined	Material examined HOLOTYPE: Australia, Queensland, Green Island, intertidal in medium to coarse coralline sand (September 1993), whole mount (lactophenol): G 211823. PARATYPES: same data as holotype, one whole mount (lactophenol) (G 211824); one specimen sagittally sectioned (G 211825). Etymology The species is dedicated to Paul M. Martens (Hasselt, Belgium), in recognition of his contribution to the knowledge of the Proseriata. Description Animals colourless, comparatively rather large: the holotype is about 5 mm long; paratype G 211824 is over 7 mm long. Anterior end elongate, provided laterally and terminally with sensory bristles. Posterior end with few adhesive glands. With two pigmented eye-spots, enclosed within the brain capsule. Epithelium entirely ciliated (cilia ranging from 2 to 3 Mm), with non-depressed nuclei. The distal edge of the epithelial cells appears strongly eosinophilous. Subepidermal longitudinal musculature well developed on the ventral side. The gut extends posteriorly nearly to the caudal tip of the body, and, anteriorly, to just behind the brain. The pharynx (gure 4 A) is located in the posterior fth of the body. It is very short and collar-shaped. Its epithelium has depressed nuclei, and is ciliated except for a small area at the distal tip, where few pharyngeal glands discharge. The nuclei of these pharyngeal glands are located well outside the pharynx itself. Pharyngeal cilia are about 1.5 Mm long. No oesophageal area could be seen. With subepidermal, longitudinal external and much weaker, inner circular musculature. The pharyngeal cavity is narrow, and opens to the outside through the mouth. The epithelium of the pharyngeal cavity is unciliated, with non-depressed nuclei. Male genital organs. Numerous testes irregularly arranged laterally among vitellaria, in front of the pharynx. The copulatory organ consists of a single seminal vesicle, and a bulb provided distally with a stylet. The seminal vesicle is narrowly elongate, and provided with a thick coating of circular musculature. The spermiducts enter the vesicle anteriorly. In one of the specimens (G 21182 4) sperm was not visible in the seminal vesicle, which was apparently degenerating. The seminal vesicle enters the bulb at its proximal base. The bulb is ovoid in shape (about 70 Mm high and 34 Mm wide in the holotype). It is lined with a thick coating of circular musculature, and provided with numerous prostatic glands, some of which have their nuclei outside the bulb itself. The stylet is thin and diaphanous, shaped as an elongate truncated cone, slightly in ated proximally. It is about 40 Mm high in the holotype, with a proximal opening 17 Mm wide, and a distal opening 9 Mm wide. Stylet of paratypes G 211824 and G 211825 are larger (respectively 60 Mm and about 55 Mm in length). The distal opening is minutely denticulate, and provided with a spike, about 6 Mm long in the holotype, and about 9 Mm in G 211824. Due to the diaphanous condition of the stylet, this spike is di cult to see in xed mounts. In living animals, it is apparently held in the sagittal plane, since it could only be seen during torsions of the caudal part of the body. The male antrum opens to the outside through a narrow male pore, which is located close to the mouth. Female genital organs. With two ovaries, consisting of one mature oocyte each, laterally in front of the pharynx. Vitellaria stretch from behind the brain to in front of the ovaries. The oviducts fuse at the level of the copulatory bulb into a common female duct, which is lined by an unciliated epithelium with non-depressed nuclei, and opens to the outside through a female pore, surrounded by numerous, long female glands, posterior to the male pore. Discussion The species is characterized by its stylet, shaped as an elongate, truncated cone, provided distally with a spike, and lacking an apophysis. Such morphology is unique in the genus, and allows immediate discrimination. Nematoplana pullolineata Tajika, 1979 has a tubular stylet without apophysis; the tube is however slightly recurved, with both openings markedly oblique, without a distal spike, and its distal opening is not denticulate. Furthermore, the species is provided with a cephalic gut and chorda intestinalis (Tajika, 1979). The stylet of N. martensi is unusual in being very thin and diaphanous, and easily deformable. This, together with its diOEerential degree of maturity, may account for the remarkable diOEerence in size among holotype and paratypes.	en	Curini-Galletti, M., Oggiano, G., Casu, M.

03F587FCA863FFBD40EDA4185C6C4235.taxon	materials_examined	Material examined HOLOTYPE: Australia, New South Wales, Byron Bay, town beach, lower intertidal in medium sand (July 1993), whole mount (lactophenol): G 21826. Other material. One immature from the type locality studied karyologically (July 1993). Etymology Named after the characteristically hooked shape (lat: hamatus) of the stylet. Description The holotype is about 5 mm long, colourless, entirely ciliated. With two pigmented eye-spots located within the brain capsule. The short, collar-shaped pharynx is located in the posterior fth of the body. Male genital organs. Numerous testes arranged in two irregular rows between vitellaria in front of the pharynx. The copulatory organ consists of an ovoid muscular bulb (about 85 Mm high and 40 Mm wide), provided with a thick outer coating of circular and inner longitudinal musculature, connected basally to a single seminal vesicle. No sperm were seen within the vesicle. Distally, the bulb is provided with a copulatory stylet. The stylet is tubular, and about 110 Mm long. The proximal end is slightly swollen, with a markedly oblique opening. The tube has a constant width (about 9 – 10 Mm) for all of its length. The distal fourth of the stylet is bent at nearly 45 ss. The distal opening is about 9 Mm in diameter, and is provided with a slit about 20 Mm long. Female genital organs. With two rows of three isolated oocytes each, laterally in front of the pharynx. Vitellaria stretch from behind the brain at the level of the seminal vesicle. Female pore behind the male pore. Karyotype. With n 58. Plates were unsuitable for a karyometrical analysis. Discussion The very long, narrowly cylindrical, distally angled stylet of the new species is unique in the genus. Nematoplan a hamata shares with N. martensi and N. pullolineata the absence of an apophysis. The stylet of N. martensi is, however, straight, distally denticulate, and with a distal spike (see above); that of N. pullolineata is smaller (about 30 Mm), and diOEerently shaped (with a proportionally much smaller distal angled part, and a nearly straight ventral side) (cf. Tajika, 1979).	en	Curini-Galletti, M., Oggiano, G., Casu, M. (2002): The genus Nematoplana Meixner, 1938 (Platyhelminthes: Unguiphora) in eastern Australia.

03F587FCA862FFA3409DA54E5E5B4250.taxon	materials_examined	Material examined HOLOTYPE: Australia, Queensland, Yeppoon, town beach, mid intertidal in very ne sand (July 1996), whole mount (lactophenol): G 211827. PARATYPE: same data as holotype, whole mount (lactophenol) (G 211828). Other material. Four specimens from the type locality studied karyologically, one of which was mature (July, 1996). Numerous juveniles observed alive. Etymology Named after a mythological, similarly monocular, population. Description Animals minute, colourless. The holotype, the largest mature specimen found, is about 1.1 mm long. Anterior end elongate, provided with sensory bristles. With a single pigmented eye-spot, shaped as an inverted Y, located within the brain capsule. Distribution of pigment granules in the eye-spot is fairly variable (gure 6 C). The small, collar-shaped pharynx is located in the posterior third of the body. Male genital organs. About 20 testes in one median line among vitellaria, in front of the pharynx. The copulatory organ consists of a single seminal vesicle, and a bulb provided distally with a stylet. The seminal vesicle enters the bulb at its proximal base. Sperm nuclei uncoiled. The bulb is spherical, about 35 Mm high in the holotype. The stylet is thin and diaphanous, irregularly brous in texture. It is shaped as a truncated cone. It is about 25 Mm high in the holotype (ranging from 18 to 27 Mm in the sample), with a proximal opening 16 Mm wide, and a distal opening 7 Mm wide. The proximal opening is markedly oblique. The distal opening is provided with a more strongly sclerotized rim, and with a distal spike. This spike is di cult to see in the whole mounts; it is about 4 Mm long in the karyological mount. Female genital organs. With two ovaries, consisting of one mature oocyte each, laterally in front of the pharynx. Vitellaria stretch from behind the brain to the level of the female pore, which opens to the outside posterior to the male pore. Karyotype. With n 55. Chromosomes diOEer slightly in length, the smallest is about three- fth of the largest. Chromosomes are meta- or submetacentric (gures 6 B, 8 I, table 2). Discussion Nematoplana cyclops is the smallest species in the genus. It is the only species with a single pigmented eye-spot — which appears clearly as the result of the fusion of the two eye-spots found in other Nematoplana species. Its diaphanous, truncated cone-shaped stylet, with a distal spike, is somewhat comparable only to that of N. martensi. It is however much smaller, comparatively shorter and broader, with a thickened, not denticulate, distal opening, and a largely oblique proximal opening. The more or less straight, cylindrical to conical stylet, without apophysis, found in N. martensi, N. hamata, N. cyclops and N. pullolineata is a very rare feature for the genus Nematoplana, and for the Unguiphora as a whole (cf. Curini-Galletti and Martens, 1992). It may be assumed to be a synapomorphic feature for the above species. They share a further very rare character for the Unguiphora, i. e. the presence of a single seminal vesicle, known, among Nematoplana species, only for one additional species, N. naia Marcus, 1949. The single-vesicle condition has been considered as a secondarily derived character status for the genus Nematoplana, resulting from the total fusion of the two partially fused vesicles found in the other species (Curini- Galletti and Martens, 1992). The presence in N. martensi, N. hamata, N. cyclops and N. pullolineata of two derived features strongly suggests that they constitute a monophyletic group within the genus Nematoplana. The position of N. naia, a Brazilian species with a tiny stylet, variously interpreted by diOEerent authors (Marcus, 1949; Ax and Ax, 1974; Curini-Galletti and Martens, 1992), cannot be determined at present. It should be noted that the derivation of the ‘ single vesicle’ status, through a ‘ two, partially fused, vesicles’ status stage (the autapomorphic feature for the genus Nematoplana), might be debatable. In fact, there is no contrary evidence that the former might not have been attained directly from the plesiomorphic condition for the Unguiphora (i. e. two wholly unfused seminal vesicles). Therefore, the above species might not share the last ancestor common to the (rest of) Nematoplana species. A generic reassessment of the Nematoplanida e should however be postpone d until a more signi cant fraction of the world species is described and character distributions more extensively mapped. Remarks Albeit only three mature specimens were found, immatures — easily recognizable due to the single eye-spot — were abundant at Yeppoon, the single locality where the species has so far been found. The very ne sediment of the town beach, lacking any obvious silt-clay fraction, yielded a distinctive, similarly minuscule (and still undescribed) proseriate fauna — whose diminutive size seems clearly related to sediment texture.	en	Curini-Galletti, M., Oggiano, G., Casu, M.

03F587FCA87CFFA140F1A5855E384275.taxon	materials_examined	Material examined HOLOTYPE: Australia, Queensland, Mackay, Shoal Point, lower intertidal in coarse sand (July 1996), whole mount: (lactophenol): G 211829. PARATYPES: same data as holotype, three specimens sagittally sectioned (G 211830 – 2). Other material. Four specimens from the type locality studied karyologically (July 1996). Etymology The species is named after the super cially similar genus Ezoplana Tajika, 1982. Description A medium-sized Nematoplana: the holotype is an adult worm, about 4.3 mm long in xed condition, without pigment or pigmented eye-spots. Anterior end elongate, provided laterally and terminally with sensory bristles. Epithelium with non-depressed (intra-epithelial) nuclei, and entirely ciliated. Cilia about 4 Mm long. Brain ovoidal, surrounded by a thin membrane. Mature specimens had two collar-shaped pharynges, lying close together. The posterior pharynx was larger, weaker and degenerating in most specimens. The anterior pharynx was smaller, and in most specimens clearly still in stages of formation. Juveniles had only one pharynx. Pharynges are located in the posterior seventh of the body. Male genital organs. Few testes irregularly arranged among vitellaria in front of the pharynx. The copulatory organ consists of two partly fused seminal vesicles, and a bulb provided distally with a stylet. The two seminal vesicles enter the bulb at its proximal base. Anteriorly, they are lined with a thin epithelium, surrounded by a thick layer of circular muscles. The muscular coating ends abruptly after about 60 Mm in the holotype. Posteriorly, the vesicles become much narrower, and they fuse caudally into one common vesicle, lined with a thin epithelium. Spermiducts enter the seminal vesicles anteriorly. The nuclei of spermatozoa are elongate, and spirally coiled. The bulb is ovoid (about 45 Mm high in the holotype). It is lined with a thick coating of circular musculature, and provided with numerous prostatic glands. The stylet is a funnel-shaped, intracellular, sclerotized structure, with a broad, oblique, ventral proximal opening and a narrow distal opening. The stylet is 37 Mm high in the holotype (measuring 40 and 41 Mm in the two semi-squashed karyological mounts). The base is about 21 Mm high in the holotype, with a maximum width of about 11 Mm. A at apophysis (about 15 Mm long) is present. It is almost of constant width along all of its length. A thick bundle of longitudinal muscles is connected proximally to the circular muscle sheath surrounding the bulb, and distally to the apophysis. The distal part of the stylet above the apophysis narrows abruptly into a nearly straight tube, about 12 Mm long. It is provided distally with a straight distal tip, orthogonal to the main axis of the stylet, and ending in a spike about 8 Mm long. The dorsal side of the stylet is thickened, particularly above the apophysis. The distal part of the stylet protrudes into a narrow male antrum, apparently unciliated. The antrum opens to the outside through a male pore, which is located close to the mouth. Female genital organs. With two, large, isolated oocytes medially in front of the pharynx. Vitellaria stretch from behind the brain to in front of the ovaries. The oviducts fuse at the level of the copulatory bulb into a common female duct, which opens to the outside through a female pore, surrounded by female glands. Karyotype. With n 53. Chromosomes diOEer only slightly in size. Chroms 1 and 2 are metacentric; Chrom. 3 is submetacentric, at the lower border of the class (gures 7 C, 8 L, table 2). Discussion Among the Unguiphora, the presence of two pharynges over at least part of the life cycle is among the de ning features of the genus Ezoplana (Tajika, 1982). However, the position of the new pharynx diOEers: in front of the ovaries and much more anterior than the old one in Ezoplana; posterior to the ovaries and close to the old one in N. ezoplanoides. Furthermore, the new species has none of the other diagnostic features of the genus Ezoplana (i. e. presence of one pair of seminal receptacles in front of the (posterior) pharynx; stylet characteristically base-less, consisting only of an apophysis and a tubular, elongate, angled distal part) (Tajika, 1982, 1988). On the contrary, it presents the diagnostic feature of the genus Nematoplana, i. e. the partial, posterior fusion of the seminal vesicles, and is hence considered as such. There are reports of pharynx degeneration during or after sexual maturity in other species of the genus Nematoplana and in Tabaota curiosa Marcus, 1950 (Marcus, 1950; Sopott, 1973; Ax and Ax, 1974; Ehlers and Ehlers, 1980; personal observation), but simultaneous formation of a new pharynx has never been observed. A life cycle which includes degeneration and reconstitution of the pharynx, may however be more widespread in the Unguiphora than hitherto hypothesized, and possibly linked to the long life span (in some cases partly biennial) of (at least some of) its representatives (Sopott, 1973; Ax, 1977). In any case, the presence of both pharynges (in various stages of development / degeneration) in adult stages of the new species, is unique in the genus, and allows immediate recognition. Furthermore, its chromosome number (n 53) is peculiar to the new species, and the lowest known among the Unguiphora. The stylets of N. ezoplanoides and N. cannoni are somewhat similar in size and general shape. However, in N. cannoni the base is slimmer, and the peculiarly angled apophysis is inserted at 45 ss with the main axis, while it is ap-like, and orthogonal to the main axis in the new species. Furthermore, the two species are immediately recognizable by the lack of pigmented eye-spots in the new species. The stylet of N. ezoplanoides is similar in size and shape to that of N. nigrocapitula, which however is pigmented, and is provided with eye-spots, cnidosacs, cephalic gut and chorda intestinalis. Nematoplana ezoplanoides, N. cannoni and N. rubra share a unique feature for the genus Nematoplana, i. e. the presence of only two oocytes, arranged medially in a single row. However, at least in N. rubra, this seems to be a transitory stage, with the plesiomorphic condition occurring in part of the life cycle. The poor knowledge of life cycles of extra-boreal unguiphorids and the limitation of sampled specimens per species do not allow inferences on the signi cance of this feature. Therefore, on a cautionary basis, it has not been used for taxonomic purposes. It should also be mentioned that no obvious synapomorphy appears shared by any of the three species above.	en	Curini-Galletti, M., Oggiano, G., Casu, M.

03F587FCA879FFA64354A6465E6543B2.taxon	materials_examined	Material examined Tasmania, Kingston, Blackman Bay, lower intertidal in medium sand (September 1993), one specimen studied karyologically. Description and remarks A medium-sized unguiphorid, with two pigmented eye-spots. With n 55. Chromosomes diOEer appreciably in length, the smallest is about one-third of the largest (table 2). Chroms 4 and 5 heterobrachial, acrocentric and subtelocentric, respectively. The specimen may belong to one of the more northern Nematoplana with pigmented eye-spots described above, whose karyotype is unknown. However, since the Tasmanian proseriate fauna as a whole appears to be quite distinct from that of mainland Australia (Curini-Galletti and Cannon, 1996 a, 1996 b; Curini- Galletti, 1998; unpublished data), it is possible that the specimen belongs to a yet undescribed species.	en	Curini-Galletti, M., Oggiano, G., Casu, M.
