Description. Head concealed by pereonite 1 and coxa 1. Body with many scattered setae; pereon and pleon without dorsal projections, not produced dorsally. 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
