Penaeopsis (Crustacea, Decapoda, Penaeidae) collected in the south-west Pacific by French expeditions since 1976. Description of a new species

This work is based on collections made in the south-west Pacific by IRD (ex ORSTOM) and the Muséum national d’Histoire naturelle, Paris. It deals with four species of Penaeopsis Bate, 1881: P. challengeri de Man, 1911, P. eduardoi Pérez Farfante, 1977, P. rectacuta (Bate, 1881), and a new species, P. mclaughlinae n. sp. Depth zones and geographic distributions of the three known species are revised, especially those of P. challengeri. Penaeopsis mclaughlinae n. sp. is closely related to P. eduardoi but it is easily distinguished by the more sinuous shape of the distal part of the ventrolateral lobules of the petasma, and the large rounded protuberance on the median plate of the thelycum.
