Four species of Pisauridae, all in the genus Dolomedes Latreille, 1804, are found in New Zealand; D. minor L. Koch, 1876 nomen protectum (=D. lateralis White, 1849, new synonymy, nomen oblitum, D. sagittiger White, 1849, new synonymy, D. imperiosus L. Koch, 1876, and D. tridentatus Hogg, 1911, new synonymy), D. aquaticus Goyen, 1888, D. schauinslandi Simon, 1899 (=D. huttoni Hogg, 1908, D. trippi Hogg, 1908, new synonymies) and D. dondalei sp. nov. The genus and all species are described, with information on synonymy, type data, material examined, and geographical distribution. Habitus images of adults, illustrations of important structural features, and distribution maps are provided. A key to adults is given. A molecular phylogenetic analysis examining the relationships of New Zealand species in the genus Dolomedes is presented. Mitochondrial DNA (cytochrome c oxidase subunit 1 – COI) and nuclear DNA (actin 5C) was sequenced from all four New Zealand Dolomedes species. COI divergence between species was low and introgression appears to have occurred between D. minor and D. aquaticus.
