The classification of Parepisparis Bethune-Baker (Geometridae: Oenochrominae) is revised. The genus occurs in New Guinea (i.e., Irian Jaya and part of Papua New Guinea) and Australia. Seventeen species are included, seven of them new. Three genera (Onychopsis Prout, Peratodactyla Turner, and Epicampyla Turner) are newly synonymized with Parepisparis. Larvae are described for two species. The monophyly of Parepisparis is based largely on the shape of the valva of the male genitalia supported, to some extent, by that of the bursa copulatrix of the female genitalia, the colour pattern of the wings and, possibly, the presence of dorsal prothoracic processes and modified setae in the larva. The Oenochrominae are a polyphyletic subfamily, with the Oenochrominae s. str. here confined to the so-called robust-bodied members of the grouping. This excludes the slenderbodied species, and various geometrid genera that have been added to the oenochromines by default.
