WA Museum Records and Supplements | Updated 1 decade ago

Abstract - Halicyclops rochai sp. nov. is described from a near-coastal aquifer in the Robe River basin. Diacyclops reidae sp. nov. and Diacyclops einslei sp. nov. are described from the Millstream aquifer in the western Fortescue Valley on the Pilbara craton. Records with large range extensions are given for Paracyclops fimbriatus (Fischer, 1853), Diacyclops humphreysi Pesce and De Laurentis, 1996, Microcyclops varicans (GO. Sars, 1863), Metacyclops mortoni, Pesce, D. Laurentiis and Humphreys, 1996 and Mesocyclops brooksi Pesce, De Laurentiis and Humphreys, 1996. The description of D. humphreysi is amplified. Halicyclops rochai sp. nov. belongs to a Tethyan group of species
and is similar to Halicyclops sp. nov. Rocha et al. from the Yucatan Peninsula, Mexico. As such, it accords with the biogeographic affinities of non-copepod elements of the fauna.
