Revision of Pseudosquillana Cappola & Manning, 1995 (Crustacea : Stomatopoda : Pseudosquillidae)

Pseudosquillana Cappola & Manning, 1995, was recognized for Pseudosquilla m egalophthalma Bigelow, 1893, and its presumed synonym, P. richeri Moosa, 19 91. Restudy of types and other material of P. megalophthalma and P. richeri revealed both species to be distinct; P. richeri is removed from synonymy. The generic definition of Pseudosquillana, previously based on diagnostic characters of both species, is redefined and an amended key to the genera o f the Pseudosquillidae is given. Both species have wide Indo-West Pacific d istributions, but most records of Pseudosquillana megalophthalma are based on P. richeri. Pseudosquillana richeri is known from the western Indian Oce an, eastwards to Indonesia, New Caledonia and now Australia, Japan, and Fre nch Polynesia. Pseudosquillana megalophthalma is known from the type locali ty, Mauritius, and now from New Caledonia. The ectoparasitic gastropod, Cal edoniella montrouzieri Souverbie is reported from P. richeri and constitute s the first record for a member of the Pseudosquillidae.
