Head anterodistal margin quadrate with cusp; ventral keel acute. Coxae 1–3 each with antero- and posterodistal cusp, coxa 4 ventrally serrate, posteriorly tapered. Gnathopod 1 basis anterior margin with few setae, posterior margin bare; carpus with one facial seta; propodus palm dentate; dactylus reaching greater than 0.2 × propodus length. Gnathopod 2 basis anterior margin with few setae; carpus tapering distally; propodus mediofacial setal row above midline, reaching 0.7 × propodus length, secondary mediofacial row with 2–4 setae, palm with several small tubercles.

Distribution.

USA: Hawaii (Thomas and Klebba 2006), South Carolina (LeCroy 2011), South Florida to the Florida Keys (Thomas and Klebba 2006); Mexico (Martín et al. 2013); Belize: Carrie Bow Cay (Thomas and Klebba 2007); Turks and Caicos Islands (LeCroy 2011); Brazil: Albrolhos (Thomas and Klebba 2006); Panama: Bocas del Toro (White 2011; present study).

Ecology and remarks.

This species occurs among sponges and coral rubble from 1– 20 m. Panamanian specimens agree closely with previous descriptions by Thomas and Klebba (2006) and White (2011) with the exception of coxa 4 having a smooth anterior margin and a slightly rounded posteroventral corner and a smooth ventral margin on epimeron 3. Living specimens are translucent pink in color with purple coloration on dorsal surface and red eyes.
