Distribution. Western Atlantic: from off North Carolina, the Gulf of Mexico and Caribbean, to off Rio Grande do Norte, Brazil. Eastern Atlantic: from the Azores and Canary Islands to the Gulf of Guinea. Depth: 850 to 3360 m.

Color ( Fig. 23 B). Freshly collected specimen (MZUSP 25787) with shield and ocular peduncles dirty white or cream. Antennules and antennae light orange. Chelipeds dirty white or cream. Ambulatory legs dirty white or cream, with ischia, meri, carpi and propodi light orange distally and along dorsal and ventral margins; dactyls light orange.

Remarks. The previous southernmost record of this species is from the southwestern Caribbean off the coasts of Panama and Colombia ( Lemaitre 1989); thus, this report extends considerably the range of this species from about 9° N off the Caribbean coast of Colombia, to 4°33’S off the coast of Rio Grande do Norte, Brazil.
