Diagnosis.

Head and body with tiny setules. Epistome weakly concave. Pereopod 6 basis posterior margin slightly concave. Pereopod 7 propodus length ~ 9 × width. Telson apex truncate.

Distribution.

Bermuda (Gable and Lazo-Wasem 1990); Panama: Bocas del Toro (present study).

Ecology and remarks.

These amphipods are associated with algae, seagrass, and coral rubble at depths of 0.5– 9 m. Panamanian specimens closely resemble previously described specimens and can be readily distinguished from Shoemakerella cubensis based on the pereopod 6 basis posterior margin, pereopod 7 propodus length relative to the carpus length, and the telson apex. Panamanian specimens are transparent white in color with brown spots when alive.
