2003. The Journal of Arachnology 31:105–121 PROBLEM SOLVING IN THE SPIDER FAMILIES MITURGIDAE, CTENIDAE AND PSECHRIDAE (ARANEAE) IN AUSTRALIA AND NEW ZEALAND Robert J. Raven and Kylie Stumkat: Queensland Museum, PO Box 3300, South Brisbane, Queensland 4101 Australia ABSTRACT. The genus Uliodon L. Koch is reviewed. It now includes only the type species, Uliodon albopunctatus L. Koch 1873, Uliodon cervinus L. Koch 1873, and Zora frenatus Koch 1873, and the genus is transferred to the Zoropsidae. Uliodon is known only from New Zealand. Through an original misreading of the type specimen locality data, both species were erroneously reported from Australia. Forster and Homann previously referred to Uliodon species as Miturga, which is endemic to Australia. The subfamily Uliodoninae Lehtinen 1967 was founded on the characters of Zora tarantulina L. Koch 1873, later transferred to Uliodon by Simon. The diagnostic character of the subfamily, the very long path of the embolus, is not found in Uliodon. The subfamily is here diagnosed from the genus; its validity is unclear. In any case, both Uliodon and Uliodoninae are transferred to the Zoropsidae along with the Australian Huntia Gray & Thompson 2001. Zora tarantulina is made the type species of a new monotypic genus, Mituliodon, included in the Miturgidae; the genus is known only from Australia and Timor. Mi- tuliodon tarantulinus (L. Koch 1873) now newly includes in its synonymy, Uliodon australiensis (L. Koch 1873), Uliodon torvus (L. Koch 1873), Miturga maculata Hogg 1900, Syspira rubicunda Hogg 1900 and Miturga velox Hickman 1930. The New Zealand genus Zealoctenus is transferred from the Ctenidae to the Miturgidae because it is very similar to the Australian genus Diaprograpta Simon 1909; the other New Zealand ‘‘ctenid’’ genus, Nemoctenus Forster & Wilton 1973, along with the Australian zorid Hor- ioctenoides Main 1954 are synonymized with the zorid genus Argoctenus L. Koch 1878, found in Aus- tralia, New Zealand and New Caledonia. The New Zealand ‘‘psechrids’’ Poaka Forster & Wilton 1973 and Haurokoa Forster & Wilton 1973 are transferred to the Amaurobiidae and Tengellidae, respectively.
