Two species of Periegopidae, both in the genus Periegops Simon, 1893, are found in New Zealand; P. suterii (Urquhart, 1892) and P. keani sp. nov. The genus and both species are described or redescribed, with information on synonymy, type data, material examined, and geographical distribution. Habitus images of adults, illustrations of important morphological features, and distribution maps are provided. A key is given.
The mitochondrial gene cytochrome c oxidase subunit 1 (COI) and the nuclear gene 28S ribosomal RNA were sequenced for both species. COI divergence between some specimens of P. suterii was unexpectedly high (8.6%, uncorrected distance), but there was no morphological differentiation or 28S sequence divergence between those specimens. A molecular phylogenetic analysis examining the relationships between eight specimens of P. suterii and three specimens of P. keani using COI data is presented.
