Antenna 1 peduncular article 1 without distal projection; accessory flagellum 2-articulate. Mandible accessory setal row with 7 robust setae; molar a setose lobe. Maxilla 1 palp long, 1-articulate. Maxilliped inner plate styliform; outer plate subovate, distomedial margin smooth, with set of small ridges on distolateral margin; palp 4-articulate. Coxa 1 rounded ventrally. Gnathopod 1 carpus shorter than propodus, subquadrate, anterior margin not produced anterodistally; dactylus regular simple. Gnathopod 2 dactylus inserted in centre of scoop formed by anterior and posterior projections of distal margin of propodus. Pereopod 7 basis, posteroventral corner subquadrate. Uropod 1 biramous; inner ramus shorter than outer ramus. Uropod 2 biramous; inner ramus shorter than outer ramus. Uropod 3 biramous. Telson laminar, notched. Remarks. Ovigerous females have no oostegites. They do have penial papillae which suggests that they are protandrous hermaphrodites as described by Lowry & Stoddart (1986) for other conicostomatine species. Distribution. Southern Australia ; 1.5–363 m depth
