A new genus is proposed for a new species widely distributed in the western Pacific Ocean from the Philippine Islands in the northwestern Pacific south to Kermadec Islands of New Zealand. Jacquesia n.g., bears considerable similarity to Iridopagurus de Saint Laurent-Dechancé, 1966, in lacking an accessory tooth on the crista dentata of the third maxilliped, but having eleven pairs of quadriserial gills, slender elongate and subequal chelipeds, and a well-developed left male sexual tube. It is distinguished from Iridopagurus by the presence of paired first pleopods in females. The new species is a very distinct, but morphologically variable species. These variations, however, do not appear to be correlated with either size or sex.
