Gnathopod 1 subchelate; larger than gnathopod 2; coxa with posteroventral corner rounded; propodus thumb absent, palm obtuse, smooth, straight; dactylus curved. Gnathopod 2 chelate; ischium long, 5 x breadth; carpus not lobate, carpus about 0.5 x length of propodus. Pereopod 3 coxa with posteroventral corner subquadrate to rounded. Pereopod 4 coxa with posteroventral lobe small or absent. Pereopod 5 basis evenly expanded, margins subparallel; merus expanded, extending half way along carpus. Pereopod 6 basis evenly expanded, margins subparallel. Pereopod 7 basis broadly expanded, posterior margin evenly convex; merus expanded, extending about half way along carpus. Pleon. Epimeron 2 posteroventral corner strongly produced. Epimeron 3 posteroventral corner subquadrate. Urosomites 2–3 coalesced. Uropod 1 peduncle shorter than uropod 2 peduncle; outer ramus shorter than inner ramus. Uropod 2 outer ramus subequal in length to inner ramus. Uropod 3 peduncle about a third of the length of ramus.

Seba mariolgae sp. nov. , holotype, female, 1.5 mm, AM P70603, Palfrey Island, Lizard Island, Great Barrier Reef. FIGURE 5. Seba mariolgae sp. nov. , holotype, female, 1.5 mm, AM P70603, Palfrey Island, Lizard Island, Great Barrier Reef. Remarks. Seba mariolgae is readily distinguished from other similar species, such as S. gruneri sp. nov. , S. tropica McKinney, 1980 , S. saundersii Stebbing,1875 , S. dubia Schellenberg, 1926 , S. chiltoni Moore, 1987 and S. antarctica Walker, 1907 by the presence of eyes and its extremely long gnathopod 2. Distribution. Australia . Queensland : Lizard Island (current study).
