Ceradocus sheardi Shoemaker, 1948: 7-9, fig. 2; Thomas 1993: 43, figs 51, 56; LeCroy 2000: 73, fig. 124.
Material examined.
Panama • 5-10 mm • 1 ♀; Bocas del Toro, Swan Cay ; 9.4536°N, 82.300033°W; depth 2 m, coral rubble; 24 June 2023; K.N. White leg.; USNM 1703495 • 1 ♂; Bocas del Toro, Cayo Zapatilla 1; 9.269967°N, 82.0587°W; depth 10-11 m, coral rubble; 28 June 2023; K.N. White leg.; USNM 1703496 GoogleMaps .
Diagnosis.
Antenna 1 accessory flagellum 7- or 8-articulate. Gnathopod 2 not sexually dimorphic, right and left sides similar; propodus enlarged, palm convex, defined by notch. Pereopod 7 basis without posterodistal lobe. Pleosome and urosome dorsally serrate. Epimera 1-3 posterior margins serrate. Telson approximately as long as wide with strong apical spines.
Distribution.
USA: South Florida from Biscayne Bay to the Dry Tortugas ( Thomas 1993); Puerto Rico ( LeCroy 2000); Cuba ( Shoemaker 1948; Varela et al. 2003); Mexico: Yucatan ( Shoemaker 1948; Thomas 1993); Belize ( Thomas 1993); Panama: Bocas del Toro (present study).
Ecology and remarks.
These amphipods are common among coral rubble and under rocks at depths of 1-52 m. Panamanian specimens agree closely with previous descriptions of the species and are easily distinguishable based on the uropod 3, gnathopod 2, and heavily serrate epimeron and urosome.
