Elasmopus elieri Ortiz, Lalana & Varela, 2004: 36-39, figs 1, 2.

Material examined.

Panama • 3.5-6 mm • 9 ♂, 9 ♀; Bocas del Toro, Lime Point ; 9.4149°N, 82.33225°W; depth 0.2-0.5 m, among red algae and coral rubble; 5 Aug 2005; S. DeGrave leg.; GCRL 6630 .

Diagnosis.

Gnathopod 1 propodus subrectangular, palm oblique. Gnathopod 2 male propodus elongate, palm concave, with large distal triangular tooth, medial surface with two subtriangular processes; female propodus elongate, narrow, palm oblique with two spines at palmar angle. Pereopod 5 basis posterior margin evenly convex. Pereopod 7 basis posterior margin without long setae. Epimeron 3 posteroventral margin with small tooth. Telson inner lobes subequal in length with outer lobes, apically rounded.

Distribution.

Cuba: Cayo Diego Pérez ( Ortiz et al. 2004); Panama: Bocas del Toro (present study).

Ecology and remarks.

These amphipods are associated with algae, and coral rubble at depths of 0-3 m. Panamanian specimens closely resemble specimens described by Ortiz et al. (2004) and can be readily distinguished from other species based on the unique shape of the gnathopod 2 propodus in males.
