CHELIPEDS (P1) & AMBULATORY LEGS (P2 to P5). - Chela long and slender, 4–7 times as long as wide (usually 6–7); dactyl of cheliped without spines on outer margin; upper and lower faces of chela smooth, without tubercles. Dactyl of second pereiopod short less than 0.3 times as long as propodus; carpus with a distoventral spine.

ABDOMEN & TELSON. - Pleurae of abdominal somites II to V with a sharp, posteriorly curved median tooth. Anteroventral margins of pleurae II to V smooth. Posterior margin of sixth abdominal tergite smooth or tuberculated, but without true spines. Male first pleopod with distal or subdistal indentation.

REMARKS. - Species of the genus are usually considered as rare. However, ten specimens of Enoplometopus gracilipes have been trapped in a single station (Rurutu Island, 280 m) which indicates that the species can be sometimes very common (Poupin, field notes).
