Abstract
The parvorder Caprellidira includes 1,244 described species in 17 families. The diverse morphology of caprellidiran amphipods ranges from thread-like to more typical laterally compressed body forms. Caprellidiran amphipods are associated with coral rubble, seagrasses, sponges, algae, and sand and typically feed on detritus from the water column. Twenty species from five families within the parvorder are documented from Bocas del Toro, Panama. Five species are new to science and a range extension is documented for 15 species. All species are diagnosed, new species are described, and an identification key to the Caprellidira amphipods of Panama is provided herein.
