The Genera Oxyethira Eaton, Gnathotrichia Ulmer and Stemoxyethira Kimmins (Trichoptera:Hydroptilidae) in Australia

Abstract

The number of non-endemic genera in the Australian Hydroptilidae is raised to five with the recognition of Oxyethira Eaton, in which four new species are described, and the referral of species to Gnathotrichia Ulmer and Stenoxyethira Eaton. The discovery of Gnathotrichia and Stenoxyethira is significant as evidence of Oriental affinities within the Australian Hydroptilidae; their taxonomic status is examined. A key to males of Australian Oxyethira is provided.
