Periclimenes poupini sp. nov., a new anemone-associated shrimp from deep-water traps (Crustacea, Decapoda, Palaemonidae)

Abstract

A new species of palaemonid shrimp, Periclimenes poupini , obtained from seven deep-sea traps, in association with anemones, from 430-560 m from the islands of Rapa, Tubuai and Gambier, French Polynesia, is described and illustrated. The new species is most closely related to another deep-water species, P. alcocki Kemp, first described from the Indian Ocean at 745 m, from which it may be distinguished by the characteristic dactyls of the ambulatory pereiopods, which have an unusually long accessory tooth, and a much larger cornea on the eye.
