Stomatopoda (Crustacea) from the Marquesas Islands: results of MUSORSTOM 9

The Stomatopoda of the Marquesas Archipelago are reported, based principally on the collections of MUSORSTOM 9. Prior to this study, 10 species of stomatopod were known from the Marquesas. Fourteen species are reported of which nine are new records for the Marquesas, and seven are new records for French Polynesia. Nineteen species of stomatopod are now known from the Marquesas. Additionally, 37 species of stomatopod are now known from French Polynesia. Several records represent important range extensions and the most important is that of Neoanchisquilla tuberculata Ahyong, 1998, previously known only from the western Indian Ocean. Moreover, the present series of N. tuberculata includes late pelagic larvae through to adults. Two new species are described: Gonodactyloideus tricarinatus n. sp., and Acanthosquilla crosnieri n. sp. G. tricarinatus n. sp. is the second species in the genus to be described and differs from its congener in having three instead of five mid-dorsal carinae on the telson. Acanthosquilla crosnieri n. sp. differs from its congeners in having two fixed spines adjacent to the articulation of the uropodal endopod. A checklist of the stomatopods known from French Polynesia is provided.
