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

Geographical distribution. Atlantic Ocean: Hollywood, Port Everglades, Miami, Lauderdale Fort Florida; GoM: Panama City, Apalachicola, Tampa Bay, Florida Keys, Florida Bay, Veracruz Reef System National Park; Caribbean Sea: Puerto Morelos Reef National Park, Quintana Roo, Puerto Rico, Tobago.

Recognition characters. Rounded rostrum; without eyes; mandibular palp with one simple terminal setae; carpus and propodus of cheliped with long simple setae on inner margin; pereopod-1 with dactylus having three spines on ventral margin and curled sensory setae on dorsal margin. Male cheliped much more robust than in female.

Remarks. This species has its geographical range extended to the southeastern portion of the GoM ( Mexico). It inhabits between 100 and 200 m perpendicular to the shoreline, in fragments of coral rock, sandy bottoms with corals and algae, in coarse sand, medium sand, fine sand, and clayey sand, at depths 15 to 53 m. It feeds by scraping organic material (e.g., microflora) from the sand. Also, it can filter fine particles of detritus.
