932B9B5A2C50FFAB1EF85E98FEFCFCDD.taxon	description	Mysid females carry their developing young in a brood pouch or marsupium, made up of overlapping petal-like plates that project ventrally from the coxae of the posterior thoracic legs. They have 8 pairs of biramous thoracic limbs, but none of them are chelate. Mysids also lack gills, gas exchange taking place through the thin membranous inner lining of the well-developed carapace, which is not attached to the last 4 thoracic segments.	en	Talbot, Suzette (2009): A survey of Mysida from the Lizard Island area, Great Barrier Reef, Australia, Subfamily Siriellinae (Crustacea, Mysida, Mysidae).

932B9B5A2C50FFAB1EF85CA6FF54F90E.taxon	discussion	Remarks. Murano (1986) proposed that the members of the subfamily be grouped into two tribes, the Siriellini, to contain all but one of the known siriellids and the Metasiriellini, to accommodate a new species, Metasiriella kitaroi, described by him from the vicinity of the Philippine Island of Panay. Its unique features and highly unusual combination of characters led him to separate it from the other siriellids. The Siriellini is made up of two genera, Siriella and Hemisiriella and is characterised by the males having pleopods with coiled or straight pseudobranchiae at the base of the endopods and by the 2 nd – 5 th male pleopods being biramous and natatory, with some species having enlarged, modified setae on the 3 rd and 4 th male pleopods, or on the 4 th only. Both genera are represented in the Lizard Island material. In Siriella, the endopods of the thoracic limbs are all of approximately the same length, while in Hemisiriella, the 3 rd thoracic endopods are stout and elongated to about twice the length of the adjacent endopods. Metasiriella kitaroi contrasts with both of these genera in the structure of the male pleopods, the 1 st, 2 nd, 3 rd and 5 th resembling those of female siriellids, in that they are small, uniramous, consist of one article only and lack pseudobranchiae. The 4 th pleopods differ in being biramous and multiarticulate, with endopods that bear a unique rectangular pseudobranchial lobe at the base and that terminate in a pair of enlarged and modified setae.	en	Talbot, Suzette (2009): A survey of Mysida from the Lizard Island area, Great Barrier Reef, Australia, Subfamily Siriellinae (Crustacea, Mysida, Mysidae).

932B9B5A2C50FFAA1EF85878FCA9FCE3.taxon	description	Each member of the genus in the Lizard Island collection has been found to have a series of fine setae, extending vertically upward from the outer margin of the uropodal endopod towards the ventral surface of the telson. These vertical setae are usually located adjacent to the otolith and may extend along the entire length of the margin. Distally they tend to be inserted near the bases of the regularly spaced lateral setae that fringe the endopod. In species such as S. vulgaris, the vertical setae appear to be structurally modified (Fig. 25 A). Their proximity to the gravity receptor and their alignment suggest that they could be involved in some aspect of orientation, possibly the perception of water movement over the surface of the endopod. Their presence has yet to be investigated in other members of the Mysidae.	en	Talbot, Suzette (2009): A survey of Mysida from the Lizard Island area, Great Barrier Reef, Australia, Subfamily Siriellinae (Crustacea, Mysida, Mysidae).

932B9B5A2C52FFA71EF85FA9FB4EF84A.taxon	discussion	Remarks. Hansen (1910) described this species as being closely allied to Siriella vulgaris. The eyes of S. affinis are darker and slightly larger than those of S. vulgaris (Figs 3 B, 23 A) and the antero-lateral spine on its antennal scale is much closer to the apex than is that of S. vulgaris (Figs 3 A, 23 C). In S. affinis the thoracic endopods are relatively robust and end in a broad dactylus and nail with a spine at the suture between them (Fig. 4 A), while in S. vulgaris, the dactylus and nail are long and slender with a fine bristle at the suture (Fig. 24 C). In both species the males have unspecialised natatory pleopods with coiled pseudobranchiae. In both, the uropodal exopod is slightly longer than the endopod (Figs 4 E, 25 B), but in the exopod of S. affinis, the outer distal corner of the proximal article is sharply angled and usually carries only 3 – 5 marginal robust setae (Fig. 4 D), while in S. vulgaris it has a more gradual curve, with about 5 – 7 robust setae extending further up the margin (Fig. 25 B). In S. affinis the uropodal endopod has 35 robust setae in its marginal row. They consist of about 11 large setae separated from each other by groups of 3 or 4 small setae. (In S. vulgaris there are 46 – 50 robust setae in the marginal row.) Both species have a slender linguiform telson reaching beyond the diaresis in the exopod and in both, the telson carries 2 stout basal setae on each side and more posteriorly, a row of lateral setae that gradually increase in size towards the apex. The Lizard Island specimen of S. affinis has 15 or 16 robust setae in each lateral row, while S. vulgaris has 17 – 21. FIGURE 3. Siriella affinis Hansen, 1910 (immature male, 5.3 mm).

932B9B5A2C5DFFA41EF85FA9FCBCF83C.taxon	discussion	Remarks. Siriella anomala is a large mysid with prominent black eyes. Males have a distinctive antennal scale in which the antero-lateral spine is positioned almost halfway down the lateral margin. At the base of the spine is a smoothly rounded concavity from which projects a strongly curved plumose seta. Beyond this the proximal lobe forms a long, fairly narrow extension terminating in a small distal lobe. Among the apical setae projecting from the lobe, the inner 2 are modified with the innermost bearing a group of flattened setules (Fig. 5 C). The antennal scale of the female is long and relatively broad (length 4 x maximum width) with an anterolateral spine near the distal end of the margin and none of the apical setae modified (Fig. 5 D). Parasites. A parasitic female choniostomatid copepod occupied the marsupium of 2 of the 9 mature S. anomala females captured. In each case the heart-shaped parasite completely filled the marsupial pouch.	en	Talbot, Suzette (2009): A survey of Mysida from the Lizard Island area, Great Barrier Reef, Australia, Subfamily Siriellinae (Crustacea, Mysida, Mysidae).

932B9B5A2C58FFBF1EF85FA9FDEEFD0D.taxon	discussion	Remarks. Like S. anomala, S. distinguenda is large, with conspicuously dark and prominent eyes, but unlike the former species, it does not exhibit sexual dimorphism in its antennal scale, the lateral spine being near the distal end of the scale in both males (Fig. 7 C) and females. Males of S. distinguenda can be recognised by the characteristic terminal armature of the modified endopods of the fourth pleopods together with their straight pleopodal pseudobranchiae. The Lizard Island specimens showed some variation from that described by Hansen (1910, Pl. V 2 c). Of the 5 males examined, 2 conformed to Hansen’s description, with a strong elongate outer seta and shorter curved inner seta extending from the terminal article and a long inner seta extending from the penultimate article (Fig. 9 D). In the remaining 3, the shortest seta was on the penultimate article and the longer 2 on the terminal article. In all but 1 of the specimens, the terminal article was extremely small and the suture between it and the penultimate article ill defined or not visible (Fig. 9 C). FIGURE 9.

Females and juveniles are difficult to identify with certainty, but the structure of the tail fan is an aid in separating them from those of S. anomala. In S. distinguenda the moderately slender telson reaches slightly beyond the diaresis in the uropodal exopod (Fig. 9 E), while in S. anomala it reaches the level of the diaresis (Fig. 6 F). The uropodal endopod of S. distinguenda carries 70 – 80 robust setae in its inner marginal row, as opposed to that of S. anomala, which has about 60. Parasites. A single S. distinguenda female contained a female choniostomatid copepod in her marsupium.	en	Talbot, Suzette (2009): A survey of Mysida from the Lizard Island area, Great Barrier Reef, Australia, Subfamily Siriellinae (Crustacea, Mysida, Mysidae).

932B9B5A2C44FFBC1EF85C77FDBBFCA1.taxon	discussion	Remarks. Features characteristic of this species are small golden-brown eyes, short broad antennal scale, natatory pleopods of males having unspecialised setae and small coiled pseudobranchiae and a tail fan in which the uropodal exopods are shorter than the endopods and the telson long and moderately broad, with the lateral robust setae terminating distally in a single long seta on each side. Pillai (1973) observed that S. gracilis exhibits some intraspecific variations and he noted a slight sexual dimorphism, the rostrum being rounded in males and acutely pointed in females. This distinction is barely visible in the Lizard Island specimens, however (Figs 10 A, B). The uropodal exopod is recorded by Ii (1964) as having 2 – 3 robust setae on the distal outer margin of the proximal article, but the Lizard Island male examined had 5 graded robust setae on its margin (Fig. 11 E), while the female had only 2. This may be a further instance of sexual dimorphism in S. gracilis.	en	Talbot, Suzette (2009): A survey of Mysida from the Lizard Island area, Great Barrier Reef, Australia, Subfamily Siriellinae (Crustacea, Mysida, Mysidae).

932B9B5A2C47FFB21EF85CA7FC43F9C0.taxon	discussion	Remarks. Like S. anomala and S. distinguenda, S. inornata is a large species, with prominent dark eyes. Males can be identified by the characteristic armature of both rami of the 4 th pleopods, while the structure of the tail fan may be used to distinguish females and young stages from those of similar species, such as S. anomala and S. distinguenda. As the differences are slight, positive identification is often difficult. In S. inornata the uropodal exopod is distinctly longer than the endopod and its distal article is fairly short and broad, less than 0.5 x the length of the proximal article, while in the other 2 species, it is narrower and at least 0.5 – 0.6 x the length of the proximal article. The telson is longer than that of the other species, reaching clearly beyond the diaresis in the uropodal exopod. Behaviour. Evidence of the strong tendency of S. inornata to migrate up into the surface layers at night is provided by Professor Grindley's series of surface plankton samples, taken every 2 hours over a 24 hour period, in the Lizard Island lagoon. The numbers of S. inornata caught were as follows: 0 at 1730 hrs, 54 at 1930 hrs, 361 at 2130 hrs, 69 at 2330 hrs, 217 at 0 130 hrs, 103 at 0 330 hrs, 5 at 0 530 hrs and 0 at 0 730 hrs (Fig. 15). This indicates that they moved into the surface layers after dark, with numbers peaking in the middle of the night and that by dawn most of them had descended to lower levels. S. inornata was also well represented in samples taken in those of the fixed traps that were set above living corals during the day and left overnight. It is probable, therefore, that this mysid shelters in or around corals during daylight hours. It appears to be markedly photophobic. It was never found in samples taken over pale backgrounds, such as sand or rubble, nor was it taken in the light trap used to sample near-reef zooplankton, even when it was placed directly over living corals. Professor Alexander’s 2 light trap samples from the lagoon contained 9 specimens of S. inornata, but since this mysid migrates into the upper water layers in large numbers at night, the presence of only a few in a trap deployed for a period of 8 hours on each of 2 successive nights suggests that it was not strongly attracted to the light source. Associated mysid species. The following 4 species were taken in more than half of the 28 samples in which S. inornata occurred; Anisomysis laticauda, A. incisa, Pseudanchialina inermis and Haplostylus pacificus. A. laticauda was present, usually in large numbers, in 25 of them.	en	Talbot, Suzette (2009): A survey of Mysida from the Lizard Island area, Great Barrier Reef, Australia, Subfamily Siriellinae (Crustacea, Mysida, Mysidae).

This tropical inshore species is known from southern Indonesian waters, the Sulu Sea, (Hansen 1910), the northern and southern Philippines (W. M. Tattersall 1951) and the Ryukyu Islands between Japan and Taiwan (Fukuoka & Murano 1997). It may also occur in the Singapore Strait (O. S. Tattersall 1960). In Australia it has been found in northern Queensland, in Princess Charlotte Bay (W. M. Tattersall 1928) and the Great Barrier Reef at Low Isles (W. M. Tattersall 1936 a), Heron Island (Fenton 1982) and Davies Reef (Carleton & Hamner 1989). The 1330 specimens from the Lizard Island survey were all caught in the lagoon, mostly in surface plankton hauls made at night, or in fixed traps set overnight above living coral heads. The 23 specimens captured by the Great Barrier Reef Expedition were recorded from comparable areas. They were taken in night tow-nettings at the Low Isles anchorage and over the Low Isles flat. Adults were caught in May and June, but only immature specimens in October and November (W. M. Tattersall 1936 a). At Lizard Island, samples were not taken in all months of the year, but mature adults, including females carrying young, were found in January, February, May and December.

932B9B5A2C47FFB21EF85CA7FC43F9C0.taxon	discussion	Remarks. Siriella lacertilis belongs to Ii's ' thompsonii ' group of the Genus Siriella. It is a member of a subgroup of species in which the frontal plate of the carapace is rounded, with an obtuse, barely developed rostrum and in which the telson is short and does not extend as far as the proximal article of the uropodal exopod. The subgroup also includes S. brevicaudata (Paulson 1875), S. hanseni (W. M. Tattersall 1922), S. lingvura (Ii 1964) and S. vincenti (W. M. Tattersall 1927). Other characteristics they have in common are; a medial pseudo-rostral spine below the anterior margin of the carapace, a pronounced cervical groove, uropods in which the exopod is longer than the endopod, with the row of robust setae on the endopod consisting of relatively few, fairly widely spaced uniform setae, not separated by groups of smaller setae. In the 3 species of the subgroup in which the structure of the labrum has been examined, i. e. S. lacertilis, S. lingvura and S. vincenti, it was found to differ from that regarded as typical of the genus. In all the other species in which its structure has been recorded, the labrum is produced anteriorly to form a large forwardly directed medial spiniform process, with a length about half to three quarters that of the basal part of the labrum. The above 3 species are exceptional in having a cordiform labrum, with a rounded anterior margin, bearing a small medial process, the length of which is about a sixth to an eighth that of the body of the labrum. Of the 5 species in the subgroup, S. lacertilis most closely resembles S. brevicaudata, as redescribed by W. M. Tattersall (1922). They are both small inshore mysids, (adult length about 6 mm) and the dimensions of their eyes (adult male cornea, 0.4 mm in diameter) and antennal scales are similar, although the eyes of S. lacertilis are red-brown in colour, while S. brevicaudata has black eyes. In both, the carapace has a conspicuous cervical groove, but the slight mid-dorsal tubercle present in S. brevicaudata, was not found in S. lacertilis. The tail fans of the 2 species differ in several respects. S. lacertilis has 3 robust setae at the distal angle on the outer margin of the uropodal exopod's proximal article, while in S. brevicaudata, the article has 5 distal robust setae. In S. lacertilis the length of the exopod's distal article is about three quarter that of the proximal article, but in S. brevicaudata it is considerably shorter, with a length only one third that of the proximal article. In S. lacertilis, the uropodal endopod has 14 – 15 robust setae in the row bordering its inner margin, while in S. brevicaudata, it has 10 – 12. The 2 species bear a strong resemblance to each other in the overall structure of the telson; in both, it is unusually truncated, with a broad, slightly emarginate posterior border, from which there extends a set of long, stout robust setae. They differ, however, in the proportions of the telson and in the number and arrangement of the setae. In S. lacertilis the width of the posterior margin is between a quarter and a third of the total telson length, but in S. brevicaudata, the apex is even broader, being half the length of the telson. In S. lacertilis, the 4 long, sub-equal posterior robust setae and the adjacent 2 rows of 7 shorter lateral setae make up a total of 18 robust setae on the distal margin of the telson, while S. brevicaudata ’ s telson has only 10 or 12 distal robust setae. These form a graded series, with the 2 longest on either side of the 3 minute central setules and 2 plumose setae of the posterior margin. Lateral to each long robust seta are 3 progressively shorter setae, followed by 1 or 2 small setae at the angle of the posterior and lateral margins. Proximally, S. lacertilis has 3 stout robust setae on either side of the base of its telson and S. brevicaudata has 2 or 3 similarly positioned robust setae. Associated mysid species. Of the 23 species found in the 19 samples containing S. lacertilis, 3 occurred in at least half of them. Anisomysys laticauda was present in 15, Pseudanchialina inermis in 14 and Anisomysis incisa in 10 of the samples.	en	Talbot, Suzette (2009): A survey of Mysida from the Lizard Island area, Great Barrier Reef, Australia, Subfamily Siriellinae (Crustacea, Mysida, Mysidae).

932B9B5A2C49FF8F1EF85942FC51FA67.taxon	distribution	Distribution. S. thompsonii is an epi-pelagic species with a world-wide oceanic distribution in warm and temperate regions. According to Pillai (1973) it is the most widely distributed mysid in oceanic waters. It is known from the north-eastern region of Australia, in the Great Barrier Reef at Low Isles (W. M. Tattersall 1936 a) and at Davies Reef (Carleton & Hamner 1989). It has also been taken in New South Wales coastal water (McWilliam & Phillips 1983) and off the west coast of Western Australia (Pillai 1973). In the Lizard Island area, 6 specimens were caught offshore at night in a plankton haul in open water 2 – 4 km E of Yonge Reef. FIGURE 19. Siriella thompsonii (Milne Edwards, 1837).

932B9B5A2C74FF8C1EF85AE8FCB5FA4E.taxon	discussion	Remarks. The 2 adult males from Lizard Island accord in almost all respects with Tattersall's (1927) description of S. vincenti from South Australia. The dimensions of the eyes and antennal scales are similar, but the eye colour recorded by Tattersall is black, while the Lizard Island specimens’ eyes are brown-gold. The antennal scales of Tattersall's specimens lack a distal articulation marking off a terminal lobe, but in 1 of the 2 Lizard Island specimens a terminal lobe is visible (Fig. 21 B). The prominent pseudo-rostral spine below the rounded rostral plate corresponds with Tattersall's description, but the carapace of the Lizard Island specimens has a conspicuous cervical groove, not noted by him (Fig. 21 A). Tattersall's account does not include a description of the labrum. In the Lizard Island specimens it resembles those of S. lingvura and S. lacertilis, in being rounded, with an obtusely curved anterior border and a short anteriorly directed medial spiniform process (Fig. 21 D). As in Tattersall's specimens, there is no articulation between the carpus and propodus of the thoracic legs (Fig. 22 C). In the tail fan the row of robust setae on the uropodal endopod contains 17 – 18 setae, all of about the same size, while in Tattersall’s Figure 97 f there are 21 correspondingly uniform setae. The telsons of the Lizard Island specimens have 4 basal robust setae on each lateral margin, as opposed to the 3 found by Tattersall. In other respects the telson matches his description. Associated mysid species. Both samples contained specimens of Anisomysis pelewensis Ii 1964, a species usually found on the sandy part of the lagoon floor.	en	Talbot, Suzette (2009): A survey of Mysida from the Lizard Island area, Great Barrier Reef, Australia, Subfamily Siriellinae (Crustacea, Mysida, Mysidae).

932B9B5A2C77FF881EF85ACCFD08F862.taxon	discussion	Remarks. Siriella vulgaris is similar to S. australis, described by W. M. Tattersall (1927) from Gulf St Vincent, South Australia. Among the features that distinguish the Lizard Island specimens from the latter are the presence of an apical lobe in the antennal scale and a small pseudo-rostral process, both of which are FIGURE 24. Siriella vulgaris Hansen, 1910. A, left 1 st thoracic limb. B, 2 nd thoracic limb. C, right 8 th thoracic limb (male). D, 3 rd pleopod (male). E, 4 th pleopod (male). Scalebars = A – E: 0.2 mm lacking in S. australis. The rostrum of S. vulgaris is slightly shorter than that of S. australis and much shorter than that of S. vulgaris rostrata, a variety of S. vulgaris recorded by W. M. Tattersall (1951) from the Philippines and Micronesia. In all three, the antennular peduncle's second article carries on its anterior margin a prominent dorsal seta that projects forward almost the entire length of the third article. The 3 rd to 8 th thoracic limbs of S. vulgaris are slender, with a long dactylus and nail. At their junction there is a thin bristle-like spine, unlike the prominent spine that Tattersall found in S. australis and that is also shown in his illustration of S. vulgaris rostrata. Associated mysid species. A total of 20 other mysid species were captured with S. vulgaris. Anisomysis laticauda was represented in all 8 samples, Siriella inornata in 6, Anisomysis incisa in 5 and Anchialina penicillata Zimmer 1915 and Pseudanchialina inermis each in 4 of the 8 samples.	en	Talbot, Suzette (2009): A survey of Mysida from the Lizard Island area, Great Barrier Reef, Australia, Subfamily Siriellinae (Crustacea, Mysida, Mysidae).

932B9B5A2C77FF881EF85ACCFD08F862.taxon	distribution	Distribution Siriella vulgaris was described from Indonesia and the Philippines (Hansen 1910). It has a widespread distribution in coastal waters in the tropical Indo-Pacific (W. M. Tattersall 1951). In north-eastern Australian waters it is known from Princess Charlotte Bay (W. M. Tattersall 1928) and the vicinity of Low Isles (W. M. Tattersall 1936 a). It has also been taken in Darwin harbour in the Northern Territory (Bacescu 1986). At Lizard Island small numbers were caught in the lagoon at night in 5 plankton tows, all but one of which were surface hauls, 24 were taken in 2 fixed traps placed above living coral overnight and 7 in an offshore plankton haul 2 – 4 km east of Yonge Reef.	en	Talbot, Suzette (2009): A survey of Mysida from the Lizard Island area, Great Barrier Reef, Australia, Subfamily Siriellinae (Crustacea, Mysida, Mysidae).

932B9B5A2C7CFF831EF85EF7FCE6FD17.taxon	discussion	Remarks. Of the 2 other species currently recognised as belonging to the genus Hemisiriella, only H. parva is known to occur in Australian waters. In comparing it with H. pulchra, Pillai (1973) pointed out differences in the structure of the telson and in the relative lengths of the uropodal endopod and exopod. While the telson of H. pulchra has 2 pairs of basal robust setae, followed by a diastema in which the concave border forms a ' waist', the telson of H. parva has 3 pairs of basal robust setae and a straight lateral border lacking a ' waist'. In H. pulchra the uropodal exopod and endopod are the same length, or the exopod is slightly longer than the endopod, which has 36 robust setae in its inner marginal row, but in H. parva the endopod is distinctly longer than the exopod and has at least 40 robust setae in its inner row. Associated mysid species. Anchialina typica orientalis Nouvel, 1971, was present in 10 of the 12 hauls in which H. pulchra was taken. The 18 other species found with it all occurred in fewer than half the samples, those most frequently represented being Promysis orientalis Dana, 1852, Anchialina penicillata and Anisomysis pelewensis, each of which were caught in 5 of the samples containing H. pulchra.	en	Talbot, Suzette (2009): A survey of Mysida from the Lizard Island area, Great Barrier Reef, Australia, Subfamily Siriellinae (Crustacea, Mysida, Mysidae).

932B9B5A2C7CFF831EF85EF7FCE6FD17.taxon	distribution	Distribution. Hemisiriella pulchra was described from Indonesia (Hansen 1910). It is also known from the South and East China Seas (Ii 1964) and has a widespread distribution in the Indian Ocean extending as far as the west coast of Australia (Pillai 1973). W. M. Tattersall (1936 a) recorded it from eastern Australian waters in the region of the Great Barrier Reef, east of Low Isles. It was taken there in a series of tow-nettings at night, when it was found to be abundant, especially in the upper water layers. The Lizard Island material consisted of young specimens, all taken in plankton hauls made at night, in dark conditions, without moonlight. Out of a total of 30, 24 were caught offshore in the open water between Lizard Island and Eagle Cay, mostly in deep hauls, and only 6 in the Lizard Island lagoon. This pattern of capture reflects the mainly oceanic distribution of H. pulchra.	en	Talbot, Suzette (2009): A survey of Mysida from the Lizard Island area, Great Barrier Reef, Australia, Subfamily Siriellinae (Crustacea, Mysida, Mysidae).

932B9B5A2C78FF831EF85BCBFB85F824.taxon	diagnosis	Diagnosis. Eyes prominent, elongate, club-shaped, laterally directed, peduncle not covered by carapace, a pair of post-orbital spines on anterior carapace border with a keel extending posteriorly from each spine towards the cervical groove, posterior 3 thoracic segments exposed. Antennal scale long and slender, outer margin straight, ending in a prominent spine that projects beyond scale apex, terminal lobe small and shallow. Endopod of 8 th thoracic limb reduced, sexually dimorphic. Abdominal pleura of males extend ventrally to form epimeral plates in I or more segments. Male pleopods biramous. Uropods slender, both exopod and endopod divided into 2 articles by a transverse suture, inner and outer margins setose. Telson linguiform, elongate, lateral robust setae distally on each margin, 2 pairs of stout, strongly serrated terminal robust setae. This small subfamily is held to be one of the earliest of the Mysidae to emerge (Meland & Willassen, 2007). It contains 16 known species, all belonging to the Genus Rhopalophthalmus. At least 2 of them, R. terranatalis from southern Africa (Wooldridge & Bailey 1982) and Rhopalophthalmus sp. from the Lane Cove River, N. S. W. (Talbot, aquarium observation) exhibit the unusual behavioural characteristic of swimming with the ventral surface uppermost, a trait otherwise unrecorded among the mysids. According to Wooldridge and Bailey’s observations, the inverted posture of R. terranatalis is associated with the method by which this primarily bottom-dwelling mysid captures its zooplankton prey. This raises the possibility that carnivory, associated with a benthic habit and inverted posture, was a characteristic of the original mysid stock, which subsequently underwent radiation to occupy a great variety of other niches.	en	Talbot, Suzette (2009): A survey of Mysida from the Lizard Island area, Great Barrier Reef, Australia, Subfamily Siriellinae (Crustacea, Mysida, Mysidae).

932B9B5A2C79FF821EF85FA9FF61FBC5.taxon	discussion	Remarks. The specimen is too badly distorted and immature to identify positively to species, however, of the 3 known Australian species, Rhopalophthalmus dakini O. S. Tattersall, 1957, R. brisbanensis Hodge, 1963 and R. constrictus Panampunnayil, 1992, it is most likely to belong to R. brisbanensis, as the anterior margin of its carapace appears to be slightly convex, a feature characteristic of this species. In R. dakini the anterior margin is straight and in R. constrictus it is produced to form a triangular rostrum. The telson of latter species has a marked distal constriction, lacking in the telson of the other two species and also lacking in that of the Lizard Island specimen. Associated mysid species. Small numbers of Anchialina typica, Anisomysis pelewensis, Hemisiriella pulchra, Doxomysis acanthina and Haplostylus parvus Hansen, 1910 were taken in the same sample as the Rhopalophthalmus juvenile.	en	Talbot, Suzette (2009): A survey of Mysida from the Lizard Island area, Great Barrier Reef, Australia, Subfamily Siriellinae (Crustacea, Mysida, Mysidae).

932B9B5A2C79FF821EF85FA9FF61FBC5.taxon	distribution	Distribution. The genus has a widespread estuarine and inshore distribution in tropical and temperate regions. In Australian waters, R. dakini, initially identified as R. egregius Hansen, 1910, has been found in New South Wales in Lake Illawarra (W. M. Tattersall 1940). Previously Tattersall (1936 a) had recorded the capture of a single small immature specimen outside Trinity Opening in the Great Barrier Reef and had referred it to R. egregius. In her survey of the genus, O. S. Tattersall (1957) transferred the Lake Illawarra specimens to a new species, R. dakini, and she suggested that the Great Barrier Reef specimen should probably be assigned to it as well. The second Australian species, R. brisbanensis was described from the Brisbane River by Hodge (1963) and the third, R. constrictus, from the south-west coast by Panampunnayil (1992).	en	Talbot, Suzette (2009): A survey of Mysida from the Lizard Island area, Great Barrier Reef, Australia, Subfamily Siriellinae (Crustacea, Mysida, Mysidae).
