A new species of bathyal pontoniinc shrimps, Periclimenes ingressicolumbi, found on an echinoid, Palaeopneustes tholoformis, is described. The host was collected off San Salvador Island in the Bahamas by means of the Johnson Sea Link II submersible at a depth of 550600 m. A morphological comparison with the closely related shrimp Diapontonia maranulus is presented.
