Remarks Rochinia kotakaeis characterised by its long divergent pseudorostral spines, very long and sharp branchial spines pointing outward, and distinctly flattened postocular and hepatic spines. This species was described based on a single female specimen collected from Tosa Bay, Japan( Takeda 2001). Ho et al. (2004)later gave a more detailed description of a male specimen that was collected from Taiwan. Richer de Forges & Ng (2013)provided photographs of specimens of R. kotakae, from the Philippines and Taiwan( Richer de Forges & Ng 2013: fig. 7). The present specimen from the SCS agrees well with the earlier material. The only other species of Rochiniaknown to have this typeof carapace pattern, with the flattened hepatic spine and very long branchial spines, is R. sibogae Griffin & Tranter, 1986, described from the Ceram Sea, Indonesia. However, in R. sibogae, the post-ocular and the hepatic foliated spine are fused ( Griffin & Tranter 1986b: fig. 12b). In R. kotakae, these two spines are clearly separated ( Fig. 8A).
Distribution This species was recorded from Japan( Takeda 2001), Taiwan( Ho et al.2004) and the Philippines( Richer de Forges & Ng 2007). This is a new record for the South ChinaSea.
