Rochinia sp. MoV 5136. — Poore et al., 2008: 56.

Material examined. Australia. WA. Off Barrow Island (21°00.24'S – 21°00.02'S, 114°22.52'E – 114°22.30'E), 399–408 m, 13 Dec 2005 (stn SS10/2005 172), NMV J53872 (1 male 28.2 x 20.7 mm). Off Ningaloo North (21°58.13'S – 21°58.45'S, 113°47.35'E – 113°47.28'E), 356– 324 m, 11 Dec 2005 (stn SS10/2005 157), NMV J53873 (1 female juvenile 14.2 x 9.9 mm). Off Red Bluff (23°59.12'S – 23°59.43'S, 112°32.02'E – 112°31.44'E), 411 m, 08 Dec 2005 (stn SS10/2005 130), NMV J54067 (1 juvenile 10.5 x 6.5 mm) .

Remarks. Rochinia carinata was described from the Kei (Kai) Islands in Indonesia and has not been recorded anywhere else since. The specimens from the south-western Australian coast differ from the typical material from Indonesia ( Griffin and Tranter, 1986a: pl. 12). The merus of pereopods 2 and 3 is cylindrical in cross section vs carinate in the Indonesian specimens. The mesogastric plate (islet) looks more ovoid in R. carinata from Western Australia whereas it is more rounded in the typical material. The pseudorostrum spines are more elongated in the specimens from south-western Australia than in the specimens from Indonesia.

The species’ range is extended from 5°S in Indonesia to 24°S, near Shark Bay, WA. The depth range in Indonesia is 204–325 m and 324–411 m in WA .
