A new family for a new genus and new species of hermit crab of the superfamily paguroidea (Decapoda: Anomura) and its phylogenetic implications

Abstract

A new family, Pylojacquesidae, is proposed for Pylojacquesia colenlani, new genus and species. Although the new family, with its monotypic genus, exhibits characters of both superfamilies of the Section Paguridea, it is tentatively assigned to the Paguroidea until additional material becomes available that would permit a more detailed study. The new family Pylojacquesidae is diagnosed, and its type genus and species are described and illustrated. The possible phylogenetic relationships of the new genus are discussed. A key to all the families of hermit crabs is presented.
