Shoemakerellacubensis, male, 4.0 mm, pereopod 7, pereopod 6, head, epistome, and upper lip, telson, gnathopod 2 lateral, uropod 2. Scale bars: 0.5 mm.

https://binary.pensoft.net/fig/1160282Diagnosis.

Head and body with tiny setules. Epistome strongly concave. Pereopod 6 basis posterior margin nearly straight. Pereopod 7 propodus length ~5 × width. Telson apex rounded.

Distribution.

USA: Panama City to Dry Tortugas, Florida (Lowry and Stoddart 1997; LeCroy 2007); Cuba (Stebbing 1897); Panama: Bocas del Toro (present study).

Ecology and remarks.

These amphipods are associated with algae and coral rubble at depths of 2–69 m. Panamanian specimens closely resemble previously described specimens and can be readily distinguished from Shoemakerellalowryi Gable & Lazo-Wasem, 1990 based on the pereopod 6 basis posterior margin, pereopod 7 propodus length relative to the carpus length, and the telson apex. Panamanian specimens are yellow-orange in color when alive.
