Diagnosis.

Gnathopod 1 coxa anteroventral corner not produced, anterior margin straight. Gnathopod 2 propodus distolateral crown with four rounded or subacute spines; dactylus apically hooked, fitting into posterodistal corner of propodus. Pereopods 6 and 7 carpus and propodus without bunches of long slender setae. Epimeron 1 posteroventral corner subquadrate; epimeron 3 posterodistal margin smooth.

Distribution.

U.S.A.: Gulf of Mexico, South Florida, Cedar Keys, Dry Tortugas, South Carolina, Georgia ( LeCroy 2000; Lowry and Springthorpe 2007); Bermuda: Flatts Village, Castle Harbor, Harrington Sound ( Kunkel 1910); Panama: Bocas del Toro (present study).

Ecology and remarks.

These amphipods are associated with sponges and coral rubble at depths of 0-12 m. Panamanian specimens closely resemble previously described specimens, with slight variation in the anteroventral margin of the head. Panamanian specimens show a minutely bifid notch rather than a single acute point.
