Abstract
New Caledonian representation of the cosmopolitan genus Oxyethira Eaton is reviewed, with the description of new species bringing to 26 the total for the genus on the island. The species are referred to three subgenera: Trichoglene Neboiss (11 species), Pacificotrichia Kelley (13 species) and Dampfitrichia Ulmer (one species) and one species is unplaced to subgenus. A key is provided to Oxyethira species of New Caledonia. In addition, new records are given for two otherwise Australian species, Hydroptila losida Mosely and Hellyethira malleoforma Wells. Points marked on a series of small maps of New Caledonia indicate the site or sites at which the species were collected. This final paper in a series of generic revisions brings the hydroptilid fauna of the island of New Caledonia to 60 species, distributed in six genera.
Highlights
The cosmopolitan genus Oxyethira Eaton exhibits a diverse array of male genital structures and arrangements
Representatives of the genus found in New Caledonia appear to be no exception
This is apparent upon consideration of the variability among 26 species recorded here, and the similarity of the considerable number of unassociated final instar larvae collected at many sites by Mary (2002) in her survey of macroinvertebrates of the island’s streams. This final paper in a series of genus-level reviews (Wells and Johanson 2012, 2014; Wells, Johanson and Mary-Sasal 2013) brings to 60 species, in six genera, the presently known hydroptilid fauna of New Caledonia, only surpassed by Ecnomidae in number of species found on the island (Espeland and Johanson 2010)
