Remarks. This species was described by Griffin and Tranter (1986b) from specimens from Ceram Island, Indonesia. The authors drew attention to the common confusion between R. sibogae and R. riversandersoni ( Alcock, 1895) from India. They gave a short key to species of this group of Rochinia where R. sibogae is clearly separated from the others by the hepatic plate fused with the postocular plate. This new locality for R. sibogae extends the range of the species far south of Indonesia, from 3°S to 20°S on the north-west slope at 1000 m, a similar depth to the type locality.
