Two new species of the new genera Anamaera (A. hixom) and Spathiopus (S looensis), both belonging to the section Gammarida of Amphipoda, are described from the Florida Keys. Anamaera is a new genus close to Maera, Ceradocus, and Ceradomaera, but has an unique combination of minor character expressions. Males of Spathiopus have an unusual paddle-shaped antenna 2 but otherwise Spathiopus appears to be an apomorph of Elasmopus.
