Neocallichirus raymanningi, a new species of ghost shrimp from the northeastern coast of Venezuela (Crustacea : Decapoda : Callianassidae)

A new species of ghost shrimp, Neocallichirus raymanningi, is described based on specimens collected in subtidal habitats in the Gulf of Cariaco, northeastern Venezuela. This new species is most similar to N. rathbunae (Schmitt), but differs from it primarily in having a broadly rounded rostrum, and in the case of males, unique armature of merus and dactylus on the major cheliped. A checklist of all known species in the world currently assigned to the genus Neocallichirus Sakai is included.
