Remarks. The morphological characters of the present specimens agree well with the original description by Spotte et al. (1994). Rostrum ( Fig. 35A–G ) upturned, reaching to about distal margin of basal segment of antennular peduncle; dorsal lamina well developed with 3–7 dorsal teeth (increasing with size), 1 postorbital; ventral tooth if present small and subdistal; ventral margin convex. Basal segment of antennular peduncle with one distolateral tooth ( Fig. 35B ); anterior margin produced. Maxilla with endite bilobed. Third maxilliped ichiomerus with distomedial mobile spine. Second pereiopods equal (small specimens) to dissimilar (large specimens); when dissimilar, dactylus of major cheliped ( Fig. 36A, B ) with single triangular tooth in proximal part of cutting edge, dorsal margin without longitudinal carina; fixed finger with broad tooth just proximal of tooth on dactylus; distal cutting edges of fingers entire; minor cheliped ( Fig. 36C, D ) similar without teeth on cutting edges. Third pereiopod propodus with about 3 ventral spines in distal half and one distoventral pair of spines. Dactylus ( Fig. 37A ) long and slender, biunguiculate; unguis about twice length of accessory tooth. Telson ( Fig. 37B ) with dorsal spines short, at about 0.50 and 0.75 of telson length; distal margin ( Fig. 37C ) rounded, without acute triangular process medially.

Colour. Colouration ( Fig. 38 ) as described and figured by Spotte et al. (1994: 217, figs. 1–2).

Ecology. Known to live in association with Antipatharia ( Spotte et al. 1994; Wicksten et al. 2014; De Grave & Anker 2017; Poupin 2018). Now recorded for the first time from Alcyonaria: A. bipinnata and P. porosa .

Distribution. Known from scattered locations in the tropical western Atlantic: Turks and Caicos Islands, Honduras (Bay Islands) ( Spotte et al. 1994; Debelius 1999); northeastern Gulf of Mexico ( Wicksten et al. 2014); Islas del Rosario, Columbia ( Corredor et al. 1979); Martinique ( Poupin 2018), and the Caribbean coast of Panama ( De Grave & Anker 2017), in depths between, 15 and 45 m. Previously recorded from Bonaire by Wicksten et al. (2014), herein recorded for the first time from Curaçao.
