Material examined. None.

Diagnosis. Shield as broad as long; rostrum rounded, unarmed; lateral projections rounded or obtusely triangular, usually with terminal submarginal spine. Ocular peduncles short, broadened distally, with corneae slightly dilated; ocular acicles triangular, with strong submarginal spine. Right cheliped with dorsal surface of palm convex (rounded or triangular); dorsal face of fixed finger, dactyl and palm with flattened or spinulose tubercles; proximal margin of palm with 3 or 4 strong spines. Carpus with row of strong spines on dorsomesial margin. Left cheliped with chela twice as long as broad; palm and fixed finger with spinulose tubercles on dorsal face; carpus with 2 short rows of strong spines on dorsal face. Ambulatory legs similar in ornamentation; propodus of left third leg usually longer than right third leg. Dactyls longer than propodi, with row of 6–9 strong corneous spines on ventral margin. Telson with posterior lobes concave medially; margins with few small spines.

Distribution. Western Atlantic: United States (Florida), Gulf of Mexico, Antilles, Colombia and Brazil (Pará).

Habitat. Usually found living associated with actinarians that completely cover its host shell. Between 50 and 550 m.
