Abstract

NEOPISOSOMA ANGUSTIFRONS (BENEDICT, 1901 ) : THE COMPLETE LARVAL DEVELOPMENT UNDER LABORATORY CONDITIONS, WITH NOTES ON LARVAE OF THE RELATED GENUS PACHYCHELES (DECAPODA ANOMURA, PORCELLANIDAE ) 1) BY ROBERT H. GORE Smithsonian Institution, Ft. Pierce Bureau, Ft. Pierce, Florida 33450, U.S.A. The porcellanid crab genus Neo pi.ro.roma as presently recognized, is a small and entirely American taxon containing five species; two from the tropical western North Atlantic, and three from the tropical eastern Pacific. The genus was estab- lished by Haig in 1960 in order to separate certain species which closely resembled members of the genus Pachychele.r, but which differed from that genus in a number of characters, most notably in the structure and number of the fragmented epimera of the carapace. In Neopisosoma, the epimera consist of a single chitinous piece embedded in membrane not extending posteriorly beyond the epibranchial area. In Pachychele.r the epimera consist of one or more small fragmented pieces embedded in membrane, extending to the posterior lateral margin of the carapace. The two genera otherwise have several features in common, among these being disparate chelipeds, either five or seven plates in the telson, and the absence of gonopods in males of some species.
