Local distribution. ( Table 1 , Fig. 2 ).

Geographical distribution. Atlantic Ocean: Bermuda, east coast of South Carolina to Florida Keys, Turkey Islands and Caicos; GoM: northeastern, southwestern and southeastern portions, Tuxpan-Lobos Protected Natural Area, Veracruz Reef System National Park, Bajos de Sisal Reef System; Caribbean Sea: Caiman Islands, Puerto Morelos Reef National Park and coast of Quintana Roo.

Recognition characters. Rostrum with a median acute process; basis of antennule with three spines on inner margin, and one spine on the outer margin at the distal end; basis of pereopod-1 with three of four spines on inner margin. Male cheliped more robust than in female.

Remarks. It inhabits coral reefs, among cnidarians ( P. guadalupensis ), sponges such as Agelas clathrodes (Schmidt) , A. fistularis , Clathria (Microciona) echinata (Alcolado) , Iotrochota birotulata (Higgin) and Monanchora arbuscula (Duchassaing & Michelotti) .
