Abstract

The three genera and four species of Larainae (Elmidae) previously described from Australia are reviewed, and one new genus and seven new species are described: Australara glaisterigen. et sp. nov., Ovolara lawrenceisp. nov., Ovolara monteithisp. nov., Stetholus carinatussp. nov., Stetholus longipennissp. nov., Stetholus metatibialissp. nov., and Stetholus woronorasp. nov. A lectotype is designated for Hydora laticeps (Carter & Zeck), and the first new collection records of the species are reported since its description in 1932. The occurrence in Australia of Potamophilinus papuanus Satô, described from Papua New Guinea, is reported. A key to the species, photographic images of the external morphology and male genitalia, distribution maps, and habitat and behavioral information, when known, are provided for all twelve species of Australian Larainae.
