Carapace broader than long. Median pair of frontal teeth separated by a wide sinus, teeth scarcely overreaching obtuse lateral frontal teeth. Orbits usually more than 3/4 frontal width. Anterolateral teeth 5, second and fourth reduced, distance between first and third usually smaller than distance between third and fifth. Cheliped with blunt lobe on upper margin of merus, carpus lacking outer spine, propodus lacking distal dorsal spine. Meri of pereiopods lacking distal dorsal spine. Fifth leg: merus broad, less than 2/3 carapace width; propodus broad, length less than 4.5 times width; propodus and dactylus subequal in length, or dactylus slightly longer. Dactili of pereiopods compressed, narrow, height at midlength much greater than width. Color: tan to cream.
Maximum depth from Ref. 97531 Inhabits the continental slope on flat foraminiferan ooze habitat, coral mounds, ripple habitat, dunes, black pebble habitat, rock outcrops, and soft-bioturbated habitat (Ref. 367). Also in muddy and muddy-sandy bottoms (Ref. 101384). Opportunistic feeder (Ref. 104380).
Life cycle: Eggs are incubated for approximately six months after which the larvae hatch. Mating behavior: Mating occurs immediately after the female's molting. Precopulatory behavior is characterized as the formation of a protective cage around the female by the male using its legs.
