Two new species of stygobitic Anzcyclops (Copepoda: Cyclopoida: Cyclopidae) from Australia

WA Museum Records and Supplements | Updated 7 years ago

ABSTRACT – Two new, small subterranean species of the genus Anzcyclops Karanovic, Eberhard & Murdoch, 2011 are described from the Pilbara region in Western Australia. Both Anzcyclops trotteri sp. nov. and Anzcyclops pearsoni sp. nov. have small known ranges. Both species are distinguished from all other described species of Anzcyclops by the highly ornamented hyaline fringe of the urosomal segments and the postero-lateral expansion of the genital somite dorsally. Anzcyclops trotteri sp. nov. can be distinguished from Anzcyclops pearsoni sp. nov. by its serrated (rather than smooth) W-shaped projection in the medial dorsal hyaline fringe of the genital double-somite of both sexes and more jagged serrations of the dorsal hyaline fringe of posterior urosomites, as well as by subtle differences in body shape and in segmentation of the antennule. A key to all known species of Anzcyclops is provided.
