Remarks. The morphological characters of the present specimens agree well with the original description by Heard & Spotte (1991). Rostrum (Fig. 63A–G) straight, or distally slightly upcurved, short, just overreaching basal segment of antennular peduncle in larger specimens, shorter in smaller specimens; dorsal lamina developed, with 2– 6 dorsal teeth at equal distances, proximalmost tooth postorbital in larger specimens; ventral lamina slightly concave with small subdistal tooth in large specimens or without teeth in small specimens. Antennal spine small (Fig. 63A, C–G); hepatic spine (Fig. 63A–G) slightly more robust, situated slightly below level of antennular spine, directed forward. Third abdominal segment not produced posteriorly. Telson with 2 pairs of dorsal spines at about 0.6 and 0.75 of telson length; lateral pair of distal spines of same size as dorsal spines; posterior margin of telson (Fig. 63H) without median process in present material while present in type-material. Basal segment of antennular peduncle with distolateral tooth, without additional teeth on anterior margin. Maxilla endite not bilobed. Ischiomerus of third maxilliped without distomedial mobile spine; with rudimentary arthrobranch. Second pereiopods equal or subequal, lacking teeth on cutting edges of fingers; fingers slender, about as long as palm, dactylus without longitudinal carina. Ambulatory pereiopods slender, with propodi straight, without spines on flexor margin except for distoventral pair, occasionally a subdistal spine is present on the ventral margin (Fig. 63J); dactyli (Fig. 63K) usually simple, seldom biunguiculate with small accessory tooth (Fig. 63J); unguis about two thirds of corpus length, delineation between corpus and unguis indistinct (Fig. 63J, K). Exopod of uropod with very small distolateral tooth flanked by distinct mobile spine (Fig. 63I).
Ecology. Lives in association with shallow-water octocorals: Antillogorgia americana (Gmelin, 1791) (cf. Heard & Spotte 1997 as Pseudopterogorgia americana); Plexaurella sp. (De Grave & Anker 2017). Herein recorded for the first time from: E. tourneforti; P. porosa; G. ventalina; P. citrina; and the antipatharian A. caribbeana.
Distribution. Known from scattered locations in the tropical western Atlantic: Florida Keys, Turks and Caicos Islands (Heard & Spotte 1991); Caribbean coast of Panama (De Grave & Anker 2017). Known to occur in depths between 1 and 12 m. Previously recorded from Curaçao by Horká et al. (2016).
