Three new ostracod genera: Humphreyscandona n. gen., Pilbaracandona n. gen., and Notacandona n. gen., and nine new species are described from subterranean waters of the Pilbara Region, Western Australia. They belong to the subfamily Candoninae of the order Podocopida, and are characterized by a 5-segmented antennula and ornamented carapace. Humphreyscandona n. gen. contains five species, all with reduced posterior furcal claw and prominent external lobe on hemipenis. The other new genera each contain two species. Pilbaracandona n. gen. is also characterized by a reduced posterior furcal claw, but can be separated from the previous genus by the chaetotaxy of the antennula, mandibula, and general appearance of the hemipenis. Notacandona n. gen. is separated from the other two new genera by having both furcal claws well developed. The new genera are more closely related to subtropical Candoninae of South America, Africa, and India than to the European ones. Morphology and taxonomy of the new genera are discussed and compared with all other living genera of the subfamily Candoninae.
