Caribbean Amphipoda (Crustacea) of Panama. Part III: parvorder Lysianassidira

Amphipods in the parvorder Lysianassidira are scavengers, often collected in sediment, coral rubble, algae, or among other invertebrates. Members of the parvorder have a head that is deeper than long, large coxae, lacinia mobilis present only on the left molar, and a mitten-shaped gnathopod 2 propodus with a long ischium. Nine species from two families within the parvorder are documented from Bocas del Toro, Panama. This research documents range extensions for eight species and an identification key to the species of Caribbean Lysianassidira of Panama is provided.
