Material examined.

Panama • 2.2–2.8 mm • 3 ♂, 1 ♀; Bocas del Toro, Crawl Caye ; 9.2459°N, 82.1369°W; depth 1–4 m, among coral rubble, 25 June 2023; K. N. White leg.; USNM 174393 About USNM GoogleMaps .

Diagnosis.

Head and pereonites 2 and 3 with dorsal projections; pereonite 4 with posterodorsal hump; pereonites with minute setae. Male gnathopod 2 propodus with distinct excavation and single grasping spine proximally. Pereopods 3 and 4 minute, bi-articulate, ~ 0.3 × length of gills. Pereopod 5 dactylus reduced to minute article. Male abdomen with two setose lobes and two setose appendages.

Distribution.

Mexico: Veracruz State ( Winfield and Guerra-García 2021); Panama: Bocas del Toro (present study).

Ecology and remarks.

This species occurs among coral rubble at depths of 1– 4 m. Panamanian specimens agree closely with previous descriptions of the species except for having five flagellar segments on antenna 1 (8 in original description) and more apically rounded pereopods 3 and 4 (triangular in original description). The size of pereopod 5 in illustrated specimen seems to be an anomaly, as all other specimens were missing pereopod 5. Variation among specimens collected in Panama includes differences in dorsal projections on body and proximal projections on gnathopod 2 and pereopods 6 and 7. Due to the morphological variation in specimens, comparison with type material is necessary to confirm the species identification. Live specimens are white in color with purple-brown splotches and a red eye.
