Latigammaropsis hermes gen. nov. , sp. nov. , holotype, male, 2.5 mm, AM P71531, female, 2.4 mm, AM P70635, Yonge Reef, Lizard Island, Great Barrier Reef. Head. Head anteroventral margin strongly recessed, extending behind posterior margin of eye; eye lageniform, small, distinctly less than one quarter head length, eyes partially situated within the lateral lobe of the head; lateral cephalic lobes rounded. Mandible palp article 3 distinctly shorter than article 2, spatulate, widest subdistally. Antenna 1 peduncular article 1 subequal with article 3; flagellum with 10 articles; accessory flagellum distinct and multiarticulate. Antenna 2 long, more than half body length, flagellum distinctly longer than peduncular article 5, with 6 articles. Pereon. Coxae 1–2 without spines on distal margin. Gnathopod 1 of distinctly different size from gnathopod 2; carpus anterior margin with fine setae only, subequal to propodus; propodus twice as long as wide, posterodistal margin evenly rounded. Gnathopod 2 basis anterior margin with few setae; carpus with distinct free posterior expansion; propodus very long, more than 2.5 x as long as carpus, posterodistal margin with robust seta and with multiple excavations; dactylus short, half length of propodus. Pereopod 3 merus with short or few long setae on anterior margin. Pereopod 5 basis with few setae, slightly expanded, distinctly longer than broad. Pleon. Urosomites 1–2 without dorsolateral spines. Epimeron 3 posterodistal margin with small spine and notch. Uropod 1 peduncle with long distoventral spine; rami distinctly unequal in length. Uropod 2 peduncle without distoventral spine; rami distinctly unequal in length. Uropod 3 peduncle subequal to the longest ramus; both rami well developed; outer ramus with terminal robust seta. Telson with terminal robust seta on each side. Female (sexually dimorphic characters). Based on female, 2.4 mm , AM P70635. Gnathopod 2 carpus without distinct free posterior expansion; propodus less than 2.5 x as long as carpus, posterodistal margin with robust seta, with no excavations; dactylus long, distinctly longer than half length of propodus. Habitat. Among sponges, Halimeda and coral rubble. Remarks . Latigammaropsis hermes sp. nov . is very similar to L. dionysus sp. nov . but has a reniform eye and longer antenna 2. The male gnathopod 1 is also more slender than in L. dionysus sp. nov. Distribution. Australia . Queensland : Lizard Island (current study).
