The mantis shrimps of the genus Raoulserenea Manning, 1995 (Crustacea: Stomatopoda: Pseudosquillidae) from French Polynesia, with the description of a new species and notes on its reproduction

Raoulserenea moorea n. sp. is described from French Polynesia based on specimens collected from inshore coral reefs. It is the smallest of the five species of the genus and further differentiated from congeners by the combination of a prominently angular rostral plate in adults, a uniform rather than reticulated colour pattern, and subtle features of the eyes, uropods, and telson. The new species is remarkable in Stomatopoda for its precocious development, and is possibly unique in becoming reproductive only one moult after postlarval settlement. Additional French Polynesian records of other species of Raoulserenea are reported, including the first documented records of R. oxyrhyncha (Borradaile, 1898) from the region. All species of the genus are now recorded from French Polynesia. A key to the species of Raoulserenea is provided and all species are figured in colour.
