dc.description.abstractParabathynellidae are small, interstitial, subterranean crustaceans, and an ancient and important element of the Australian aquifers. Many taxa have been discovered in the past few decades, especially in the north of Western Australia, due to surveys conducted on behalf of the mining industry for compliance with Western Australian environmental legislation. Molecular data has become a valuable tool in delimitation of species, especially for environmental impact assessments. However, formal descriptions rarely follow. Here we describe 12 new Parabathynellidae species and three additional putative species delimited initially by genetic data. Using an integrative approach we describe three species of Hexabathynella (H. miralgaensis sp. nov., H. julianae sp. nov., H. robeensis sp. nov.) and seven species of Atopobathynella (A. abelloana sp. nov., A. beasleyensis sp. nov., A. runhami sp. nov., A. jessicae sp. nov., A. shawensis sp. nov., A. rudini sp. nov., A. pervulgata sp. nov.) from the Pilbara region; and two species of Kimberleybathynella (K. ordensis sp. nov. and K. callani sp. nov.) from the Kimberley region. A multigene phylogeny was reconstructed from DNA sequences of the Cytochrome Oxidase c Subunit I (COI), 12S rRNA (12S), and nuclear 18S rRNA (18S) for representative taxa from Australia and other countries. The phylogeny highlighted interesting relationships between species and genera, and raises doubts regarding the validity of the genus Kimberleybathynella.
