CARAPACE. - Lateral edge of rostrum with four spines (varying from 3 to 5 spines). Carapace armed with five median spines; two postcervical spines; three lateral spines; one intermediate spine; one supra-ocular spine.

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. Telson with two lateral spines; and two distolateral spines.

DISTRIBUTION. - West Pacific: New Caledonia (Loyalty Islands). - South central Pacific: French Polynesia, Austral Islands (Rimatara, Rurutu, Tubai), Society Islands (Bora Bora, Tupaï); Tuamotu Islands (Fangataufa, Moruroa). Deep distribution: 125–300 meters.

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).
