Remarks. The morphological characters of the present specimens agree well with the original description by Chace (1942) and figures provided by Holthuis (1951b). Rostrum (Fig. 64A, B) straight, slightly directed downward, reaching distal margin of distal segment of antennular peduncle; dorsal lamina not developed, with 7–8 dorsal teeth at equal distances, all on rostrum proper; ventral lamina straight or slightly concave with 1–2 small teeth distally. Hepatic tooth at level of antennular tooth, directed forward. Third abdominal segment not produced posteriorly. Telson (Fig. 64D) with 2 pairs of small dorsal spines at about 0.6 and 0.8 of telson length; lateral distal pair of same size as dorsal spines; posterior margin of telson (Fig. 64E) entire, without small triangular process. Basal segment of antennular peduncle (Fig. 64C) with distolateral tooth and additional 2 teeth on anterior margin. Maxilla with endite bilobed. Ischiomerus of third maxilliped without distomedial mobile spine. Second pereiopods dissimilar and unequal; fingers of major chela with pair of low teeth in proximal part of cutting edge each; movable finger curved, with distinct dorsal carina, fixed finger as broad as movable finger, ventral margin glabrous.Ambulatory pereiopods with propodus straight, with two ventral distally serrate spines in distal part (Fig. 64F) and two distoventral distally serrate spines. Dactylus of third pereiopod (Fig. 64F) with slightly concave flexor margin; accessory tooth distinct, subdistal and slender; dorsal margin with small scale-like structure at joint with unguis; unguis slender, about half length of corpus.

Ecology. The species is known to live in association with the basket star Astrophyton muricatum (Lamarck, 1816) (Chace 1942; Horká et al. 2016; Faasse 2016; De Grave & Anker 2017; Poupin 2018).

Distribution. Known from scattered locations in the tropical western Atlantic: Florida (Chace, 1942; Holthuis 1951b), Santa Marta, Colombia (Criales 1984), Sint Eustatius (Faasse 2016), Caribbean coast of Panama (Felder et al. 2009; De Grave & Anker 2017), and Sint Maarten and Martinique (Poupin 2018). Occurring in depths between 1 and 10 m. Previous record from Curaçao by Horká et al. (2016). Herein recorded for the first time from Bonaire.
