Diagnosis.

Anamorph male. Head with lateral ridge, anterior margin concave, without anterodistal notch, ventral keel rectangular. Gnathopod 2 basis with acute process subdistally; propodus palm with three teeth.

Leucomorph male and female. Head ocular lobe rounded; ventral keel rounded, subacute distally. Gnathopod 1 propodus margin finely serrate with several small setae; carpus dentate and finely serrate, terminal spines smooth with terminal bulb. Gnathopod 2 propodus palm oblique with several serrations.

Distribution.

USA: Georgia to the Florida Keys (Thomas 1997); Belize: Carrie Bow Caye (Thomas 1997); Mexico (Martín et al. 2013); Venezuela (Martín et al. 2013); Panama: Bocas del Toro (White 2011; present study).

Ecology and remarks.

This species occurs among sponges, Halimeda, Thalassia, and coral rubble at depths of 1– 11 m. Thomas (1997) reported this species from solitary ascidians at depths to 20 m. Panamanian specimens agree closely with previous descriptions of the species. Anamorph males have an anterior tubercle on the gnathopod 2 basis that was not illustrated in original description as noted by White (2011). Living anamorphs and leucomorphs are translucent with pale brown stripes and have red eyes.
