Redescription of two species of Pseudodiaptomus from Asia and Australia (Crustacea: Copepoda: Calanoida: Pseudodiaptomidae) with discussion of the female genital structure and zoogeography of Indo-West Pacific species

摘要

Many species of Pseudodiaptomus are known from the southeast Asia region. An ongoing review of this genus has produced 58 species from the eastern Indian Ocean and western Pacific Ocean coasts, from Japan to Australia. Range extensions for P. ornatus and P. andamanensis are noted for Australia and Japan, and for Thailand respectively. The previously unknown male of P. ornatus and the female genital structure of both species are described; the zoogeography of the genus is discussed.
