Mandible palp article 2 without posterodistal seta. Habitat. Bamarooka tropicalis has been found with algae, seagrasses, sediments, ascidians, bryozoans and hydroids, but most commonly among corals and coral rubble in 3–40 m depth. Remarks. Bamarooka tropicalis is a widespread species in tropical Australia. It is currently the only species of Bamarooka known from the GBR. It can be separated from other GBR lysianassoids by its elongate head. Bamarooka anomala and B. tropicalis are the only species in the genus with elongate, reniform eyes. They are easily distinguished from each other by their fifth pereopods, which have a linear basis in B. anomala and an expanded basis in B. tropicalis. The shape of pereopod 7 basis is slightly variable within the species. In populations from the North West Shelf the posteroventral margin is almost always rounded; in east coast populations it varies from rounded to almost straight (as in illustrated specimen). Distribution. Australia. Queensland: Northwest Islet, Hammond Island and Goodes Island, Torres Strait (current study); Lizard Island (Lowry & Stoddart 2002, current study).

Antenna 1 with weak 2-field callynophore; calceoli present. Antenna 2 calceoli present. Habitat. Scavenger living among soft and hard corals in 3 to 50 m depth. Remarks. According to Lowry & Stoddart (1995) Riwo mizeui is a scavenger which occurs on living coral bottoms. It is the only lysianassid known from the Great Barrier Reef which has both a simple first gnathopod and distinctly unequal rami on uropod 3. Pseudambasia acuticaudata also has unequal rami on uropod 3, but the first gnathopod is weakly subchelate. Riwo mizeui differs from Shoemakerella barnardi, which also has a simple gnathopod 1, in the size of the eyes which cover most of the head (smaller in S. barnardi), the presence of robust setae on the distal margin of maxilla 1 palp (serrate in S. barnardi) and epimeron 3 which is narrowly rounded (broadly rounded in S. barnardi). Living specimens R. mizeui have a black-speckled chromatophore pattern on the body (body white in S. barnardi). Distribution. Australia.

Mandible molar a setose tongue; palp attached midway, article 3 without A3-setae. Maxilla 1 outer plate with setal-teeth in 7/4 crown arrangement (see Remarks); setal-tooth 7, left and right symmetrical, cuspidate distally; palp distal margin with apical robust setae and serrations. Maxilliped inner plates poorly developed, not reaching half the length of the outer plate; outer plates without apical robust setae; palp 4-articulate, article 4 well developed. Pereon. Gnathopod 1 simple; coxa large, about as long as coxa 2, subrectangular with straight anterior margin; basis without setae along anterior margin; ischium long (length 2.4 x breadth); carpus long (length 2.2 x breadth), distinctly longer than propodus, without posterior lobe; propodus margins tapering; dactylus complex, with 2 large subterminal spines and row of short spines along posterior margin. Gnathopod 2 chelate; carpus longer than (1.7 x) propodus; palm obtuse; dactylus minute. Pereopod 4 coxa with well developed posteroventral lobe. Pereopod 5 coxa equilobate; basis distinctly longer than broad. Pereopod 7 basis posterodistally produced. Pleon. Epimeron 3 posterodistal corner rounded. Urosomite 1 with anterodorsal notch and slightly rounded boss. Uropod 1 rami subequal. Uropod 2 rami subequal, inner ramus with slight marginal constriction. Uropod 3 without plumose setae on rami; outer ramus 2-articulate, article 2 long, inner ramus extending beyond article 1 of outer ramus. Telson subequal in length and breadth, entire, without dorsal robust setae, with 2 apical robust setae. Male (sexually dimorphic characters). Based on paratype male, 2.1 mm, AM P41607. Antennae 1–2 with calceoli. Antenna 1 flagellum with strong 2-field callynophore. Habitat. Scavenger living on muddy bottoms from the littoral to the continental slope, in 15 to 500 m depth. Remarks. The illustrated specimen has the uropod 3 inner ramus slightly shorter than the outer ramus; in the holotype the rami are subequal. We have seen some variation in the relative lengths of these rami but the inner ramus is always longer than article 1 of the outer ramus and always shorter than the entire outer ramus. The presence of 12 setal-teeth on the maxilla 1 outer plate of the illustrated specimen seems to be an individual aberration. Other Australian specimens have the normal 11 setal-teeth in a 7/4 crown arrangement. Nagada uwedoae occurs from northern Papua New Guinea along the east coast of Australia from the northern Great Barrier Reef to Tasmania (Lowry & Stoddart 1995, 2003). It can be separated from other lysianassoid species on the GBR by the combination of head and body without scattered setae, gnathopod 1 simple and the posteroventral corner of the third epimeron broadly rounded.

No full textParalysianopsis padoz Lowry & Stoddart, 1995 (Figs 11, 12) Paralysianopsis padoz Lowry & Stoddart, 1995: 106, figs 3, 4. Material examined. 1 male, 2.0 mm, AM P69600 (QLD 687); 2 unsexed, AM P69601 (QLD 690); 1 unsexed, AM P69602 (QLD 698); 1 female, 3.8 mm, AM P69603 and 14 unsexed, AM P69604 (QLD 699); 3 unsexed, AM P69605 (QLD 700); 4 unsexed, AM P69606 (QLD 747); 14 unsexed, AM P69607 (QLD 748). Type locality. Padoz Tinan Reef, Madang Lagoon, Papua New Guinea (5º09.53'S 145º48.88'E), 2 m depth. Description. Based on female, 3.8 mm, AM P69603. Head and body. Body without dorsal carina. Head lateral cephalic lobes subtriangular, with apically subacute margins; eyes ovate. Antenna 1 subequal to antenna 2; flagellum with weak 1-field callynophore, robust setae absent from proximal articles; calceoli absent; accessory flagellum with 5 articles, setose medially. Antenna 2 less than 40% of body length; peduncle with strong brush setae; calceoli absent. Mouthparts forming a subquadrate bundle. Epistome / upper lip separate, epistome less produced than upper lip, narrowly rounded; upper lip produced, rounded apically. Mandible molar with reduced column and convex fully triturating surface; palp attached midway, article 3 without A3-setae. Maxilla 1 outer plate with setal-teeth in 6/5 arrangement; setal-tooth 7, left and right symmetrical, cuspidate distally; palp distal margin with apical robust setae. Maxilliped inner plates well developed, greater than half the length of outer plate; outer plates without apical robust setae; palp 4–articulate, article 4 well developed. Pereon. Gnathopod 1 weakly subchelate; coxa large, about as long as coxa 2, subrectangular with straight anterior margin; basis expanded distally, sparsely setose along anterior margin; ischium short; carpus short (length 1.6 x breadth), subequal in length to propodus, without posterior lobe; propodus longer than broad, margins tapering, palm acute, entire, straight; posterodistal corner with robust seta; dactylus inner margin with large subapical spine. Gnathopod 2 chelate; carpus longer than propodus; palm slightly obtuse; dactylus minute. Pereopod 4 coxa with well developed posteroventral lobe. Pereopod 5 coxa anterior lobe slightly deeper than posterior lobe; basis about as long as broad, with well developed, rounded posteroventral lobe. Pleon. Epimeron 3 posterodistal corner rounded. Urosomite 1 dorsally straight. Uropod 1 rami subequal. Uropod 2 rami subequal, inner ramus without marginal constriction. Uropod 3 rami subequal, without plumose setae; outer ramus 2–articulate, article 2 long (more than half length of article 1), inner ramus extending beyond article 1 of outer ramus. Telson longer than broad, entire, with dorsal robust setae. Male (sexually dimorphic characters). Based on male, 2.0 mm, AM P69600 (QLD 687). Antenna 1 flagellum with weak 2-field callynophore (stronger than female); accessory flagellum moderately setose medially. Habitat. Scavenger living in rubble at 2 to 30 m depth. Remarks. The morphology of the Paralysianopsis padoz population from Ashmore Reef, Queensland is extremely similar to that of the population from Madang Lagoon, Papua New Guinea. The only discernible differences are the lateral cephalic lobes which are subtriangular in shape in the Ashmore Reef population (a semidome in the Madang population) and the accessory flagellum which is much more setose in the Ashmore Reef population. Paralysianopsis padoz can be distinguished from other lysianassids on the Great Barrier Reef by the weakly subchelate gnathopod 1 and broadly rounded posteroventral corner on epimeron 3.
