LOCATION OF TYPES SPECIMENS. - Zoölogisch Museum, Amsterdam (ZMA, 1 holotype and 1 paratype De 101.265).
MATERIAL EXAMINED. - West Indian Ocean: Réunion, coll. Y. Plessis, 1973, 1 male cl 22.5 mm (MNHN As 271). - Indonesia: Banda Islands, leg E. van der Velde May 1921, female holotype cl 33 mm, male paratype cl 30 mm (ZMA De 101.265). - French Polynesia: Austral Islands, Rurutu, coll. Frv Marara, st. 423, 10.VIII.1991, 22°29.3'S, 151°21.6'W, trap 80 m, 1 male cl 29 mm, lt 96 mm (MNHN As 624); Society Islands, Tahiti, unknown collector, dry remains of chelae only with this label ‘Hoplometopus gordonae sp. nov.’ (MNN As 625).
CARAPACE. - Lateral edge of rostrum with three spines, or four spines. Carapace armed with five median spines; two postcervical spines; three lateral spines, or four 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 4.6–6.4); 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 (verified on types specimens; however, few denticles observed on pleurae II-III on a specimen from La Réunion MNHN As 271). Posterior margin of sixth abdominal tergite with 2 short spines. Male first pleopod with distal or subdistal indentation. Telson with two lateral spines; and two distolateral spines.
COLORATION. - Ground color of body orange red. Lateral face of carapace with a large white circle (and wavy white lines posteriorly). Ambulatory legs orange red with narrow white bands. Abdomen with several ocellated spots (abdominal somites bear a large median white spot on the dorsal face and a white red-ringed spot at the base of the pleurae).
DISTRIBUTION. - West Indian Ocean: Réunion. - Indonesia: Banda Islands, Moluccas. - Philippines. - West Pacific: Marshall Islands (Enawetak atoll). - Central Pacific: Hawaii; French Polynesia: Austral Islands (Rurutu), Society Island (Tahiti), Tuamotu. Deep distribution: 20–80 meters.
REMARKS. - Specimen from Austral Islands, illustrated in Poupin (1996b) under Hoplometopus sp. nov. is now affiliated to E. holthuisi despite small differences in coloration of lateral face of carapace and fingers of chela being shorter with outer margins furnished with very long setae (see illustrations). These differences are attributed to the small size of the specimen. A new species could be considered only with the discovery of further specimens sharing the same particularities.
