Resupinus spinicaudatus Thomas & J.L. Barnard, 1986b: 445-454, figs 1-5.

Material examined.

Panama • 2-2.5 mm • 2 ♂, 6 ♀; Bocas del Toro, Drago; 9.413433°N, 82.33335°W; depth 0-1 m, in sand; 23 June 2023; K.N. White leg.; USNM 1703551 .

Diagnosis.

Head eye not filling entire ocular lobe. Pleosome segments 2 and 3 with dorsal serrations. Urosome segments dorsally smooth. Epimera 1-3 with sparse facial setae; epimeron 3 posterior margin with sparse, shallow serrations. Telson covered with dorsal prickle spines.

Distribution.

Belize: Sitee Point (Thomas and Barnard 1986b); Panama: Bocas del Toro (present study).

Ecology and remarks.

These amphipods are found in sand at depths of 0.75-1.2 m. Panamanian specimens closely resemble previously described specimens and can be easily identified based on having smooth pleonites 4 and 5, sparsely serrate epimeron 3, and dorsally spinose telson.
