Examination of museum specimens belonging to the cyphophthalmid Gondwanan family Pettalidae has rendered a collection of specimens placed in the new genus Karripurcellia. The genus includes three species, K. peckorum, sp. nov., K. sierwaldae, sp. nov. and K. harveyi, sp. nov., from the Pemberton area in Western Australia. These are the first cyphophthalmid species found outside Queensland in Australia. Karripurcellia, gen. nov. is distinguished from other Australian pettalids by the lack of modifications in the anal plate, as well as the lack of the typical male anal glands of pettalids, sironids and the stylocellid genus Fangensis Rambla, 1994. Two of the species, K. peckorum, sp. nov. and K. sierwaldae, sp. nov., live sympatrically and have been collected in the same litter samples in one locality. The proposition of the new genus is accompanied by a cladistic analysis of all pettalid genera and most species within each genus, with the exception of the species-rich genus Rakaia Hirst, 1925. The cladistic analysis supports the monophyly of the Karripurcellia, gen. nov. species, but their sister-group relationships are unclear. However, the remaining Australian species cluster with the pettalids from New Zealand and South Africa, but not with Karripurcellia, sp. nov.
