description: <i>Latigammaropsis athenae</i> sp. nov. (Figs 5, 6, Pl. 5D) <b>Type material.</b> Holotype, male, 5.0 mm, AM P71191, North Point, Lizard Island (14°38’45”S 145°27’18”E), coral rubble from granite rock face with some corals, turf algae, 16 m, C. Rakocinski, 28 February 2005 (QLD 1728). Paratypes: 1 male, 2 females, AM P75470, same data as holotype. <b>Additional material examined.</b> 1 male, AM P71182 (QLD 1730); 1 female, AM P71218 (QLD 1768). <b>Type locality.</b> North Point, Lizard island, Queensland, Australia (14°38’45”S 145°27’18”E). <b>Etymology.</b> Greek mythology: <i>Athenae</i>, the Goddess of domestic arts. <b>Description.</b> Based on holotype, male, 5.0 mm, AM P71191. <b>Head.</b> <i>Head</i> lateral cephalic lobes rounded, anteroventral margin strongly recessed, extending behind posterior margin of eye. Eye lageniform, large, one quarter or more of head length, partially situated within the lateral lobe. <i>Mandible palp</i> article 3 spatulate, widest subdistally. <i>Antenna 1</i> peduncular article 1 longer than article 3; flagellum with 11 articles; accessory flagellum distinct and multiarticulate. <i>Antenna 2</i> short (distinctly less than 1/2 body length); flagellum distinctly longer than peduncular article 5, with 8 articles. <b>Pereon.</b> <i>Coxae 1–2</i> without spines on distal margin. <i>Coxa 1</i> not distally acute. <i>Gnathopod 1</i> distinctly different in size from gnathopod 2; carpus anterior margin with fine setae only, subequal in length to propodus; propodus between 1.5 and 3 x as long as wide, posterodistal margin evenly rounded. <i>Gnathopod 2</i> basis anterior margin with dense long setae; carpus with distinct free posterior expansion; propodus very long, 4 x as long as carpus, posterodistal margin with robust seta, and with a single excavation; dactylus distinctly longer than half length of propodus. <i>Pereopod 3</i> merus with few setae on anterior margin. <i>Pereopods 5–7</i> basis with few setae. <i>Pereopod 5</i> basis extremely expanded, as long as broad. <b>Pleon.</b> <i>Urosomites 1–2</i> without dorsolateral spines. <i>Epimeron 3</i> posterodistal margin rounded. <i>Uropod 1</i> peduncle with long distoventral spine; rami distinctly unequal in length. <i>Uropod 2</i> peduncle with distoventral spine; rami distinctly unequal in length. <i>Uropod 3</i> biramous; peduncle subequal to the longest ramus; both rami well developed; outer ramus with terminal robust seta. <i>Telson</i> with terminal robust seta on each side. <b>Female</b> (sexually dimorphic characters). Based on paratype female 5.0 mm, AM P71191. <i>Gnathopod 2</i> basis anterior margin with few setae; propodus long, less than 2.5 x as long as carpus, palm with weak excavation. <b>Habitat.</b> Coral rubble and encrusting algae. <b>Remarks.</b> This species is most similar to material described under the name <i>Gammaropsis atlantica</i> from Hawaii by Barnard (1970), but differs in the female gnathopod 2. In present material the propodus of that appendage has a very weak excavation on the posterior margin, that extends from the short palm to a proximal position. In Hawaiian material the acute palm terminates with a small tooth at the posterior margin. <b>Distribution.</b> <i>Australia</i>. Queensland: Lizard Island (current study).
