Remarks. This species was described from the Siboga material from Indonesia ( Griffin & Tranter 1986: 178, figs. 56, 64e, f, pl. 12) and is characterised by a rounded carapace with a short, bifid rostrum and a series of large flattened swellings on the dorsal surface. The lateral border of the carapace has a thin, lamellated plate and the swellings are arranged as follow: one round and flat mesogastric plate, one ovoid and flat cardiac plate and two rounded and flat branchial plates. The border of the cheliped propodus is also carinated. The thin, flattened plate on the lateral border of the carapace is very similar to that of Oxypleurodon nodosum ( Rathbun, 1906) .

Laubierinia carinata was described from Indonesia (Kai Islands) and it was recently recorded from Western Australia (Richer de Forges & Poore 2008). It is recorded herein from the Solomon Islands, New Caledonia and the Norfolk Ridge seamounts, extending the range to the Pacific Ocean.

The live colour is bright red ( Fig. 11 D).
