Head anterodistal margin rounded; ventral keel rounded. Gnathopod 1 basis anterior margin with 0–1 seta, posterior margin bare; propodus palm serrate; dactylus reaching more than 0.2 × propodus length. Gnathopod 2 basis anterior margin with six short setae; carpus distally expanded, anterior margin dentate; propodus primary mediofacial setal row above midline, reaching 0.7 × propodus length, secondary mediofacial row with two or three setae, submarginal setal row present, palm with several small tubercles. Coxa 4 posterior margin slightly concave. Epimeron 3 posteroventral corner subquadrate.

Distribution.

USA: South Florida, Florida Keys; Bahamas; Puerto Rico: Vieques; Mexico (Martín et al. 2013); Belize: Whale Shoals; Honduras: Roatan (Thomas and Klebba 2006); Panama: Bocas del Toro (White 2011; present study).

Ecology and remarks.

This species occurs as a commensal in sponges and among coral rubble and algae at depths of 1– 12 m. Panamanian specimens agree closely with previous descriptions of the species, with the exception of having gnathopod 1 coxa anterodistal corner smooth (vs serrate), carpus with distal setae (vs bare), and variation in the number of setae on gnathopod 2, remaining coxae, and pereopod 5–7 bases as noted by White (2011). Living specimens are translucent orange with a red eye.
