Description
Seba zeumindi sp. nov.
(Figs 6, 7)
Type material. Holotype, female, 0.9 mm, AM P77558, Cobia Hole, Lizard Island (14°39.154’S 145°26.851’E), coarse sediment with shell and coral, among patches of reef, core, 17 m, M. Yerman, 25 February 2005 (QLD 1663).
Type locality. Cobia Hole, Lizard Island, Queensland, Australia.
Etymology. Named after my (MNY) two loyal canine companions, Zeus and Mindy.
Description. Based on the female holotype 0.9 mm, AM P77558.
Head. Head eyes present. Antenna 1 peduncular article 1 subequal in length to article 2; article 2 length, 2 x breadth.
Pereon. Gnathopod 1 subchelate; smaller than gnathopod 2; coxa with posteroventral corner rounded; propodus palm obtuse, smooth and straight; dactylus is curved. Gnathopod 2 chelate; ischium short, 3.25 x breadth; carpus about 0.5 x length of propodus. Pereopod 3 coxa with posteroventral corner subquadrate, or with posteroventral corner rounded. Pereopod 4 coxa with posteroventral lobe small or absent. Pereopod 5 basis evenly expanded, margins subparallel; merus expanded, slightly extending along carpus. Pereopod 6 basis evenly expanded, margins subparallel. Pereopod 7 basis broadly expanded, posterior evenly convex; merus expanded, slightly extending along carpus.
Pleon. Epimeron 2 posteroventral corner weakly produced. Epimeron 3 posteroventral corner rounded. Urosomites. Uropod 1 peduncle shorter than uropod 2 peduncle; outer ramus shorter than inner ramus. Uropod 2 outer ramus slightly shorter than inner ramus. Uropod 3 peduncle about half length of ramus. Telson longer than broad, lateral margins slightly convex.
Habitat. Coarse sediment with shell and coral, among patches of reef.
Remarks. Seba zeumindi is similar to S. mariolgae in that it also possesses eyes. It can however, can be distinguished from other similar species, such as S. tropica McKinney, 1980, S. saundersii Stebbing,1875, S. dubia Schellenberg, 1926 and S. antarctica Walker, 1907, by the slight extension of the merus along the carpus on pereopods 5 and 7. The posteroventral corner on epimeron 3 is rounded, similar to S. stoningtonensis Thurston, 1974 and S. subantarctica Schellenberg, 1931 and the rami on uropod 2 are subequal in length.
Distribution. Australia. Queensland: Lizard Island (current study).
