A new species of Pseudodiaptomus (Copepoda, Calanoida, Pseudodiaptomidae) from the Great Barrier Reef, Australia.

A new species of the demersal calanoid copepod genus Pseudodiaptomus is described from specimens collected from the Great Barrier Reef, Australia. This species most closely resembles P. burckhardti in the structure of male fifth leg with reduced endopods on both legs, but differs from the latter in several features, including armatures of male fifth leg, asymmetrical female urosome and posterodorsal projections on the male prosome.
