Diagnosis.

Head ocular lobe subacute. Epistome produced, rounded, subequal to produced upper lip. Gnathopod 1 basis slender, elongate; propodus distally narrowing. Gnathopod 2 minutely subchelate. Telson partially cleft, lobes apically rounded.

Distribution.

USA: Santee River, South Carolina ( LeCroy 2007); off Sapelo and Little Tybee Islands, Georgia ( LeCroy 2007); Dry Tortugas ( Shoemaker 1933); Gulf of Mexico from Florida Keys to Panama City ( Thomas 1993; Lowry and Stoddart 1997; LeCroy 2007); Belize ( Thomas 1993); Panama: Bocas del Toro ( Miloslavich et al. 2010; present study).

Ecology and remarks.

These amphipods are associated with coral rubble and coarse sand at depths of 1– 80 m. Panamanian specimens agree closely with previous descriptions of the species. This species is easily recognizable by the subacute ocular lobe, produced epistome and upper lip, and slender, elongate basis of gnathopod 1. Panamanian specimens have a distinct red coloration on the tips of antennae and on the anterior half of the body and have a white snowflake pattern on the posterior half of the body when alive.
