Abstract
The Oceanian country of New Caledonia has been shown to have a great diversity of Trichoptera, but prior to this work only 3 species from the large Leptoceridae genus Triplectides were known from there. Extensive sampling on the main island, Grande Terre, revealed 11 new species in the genus, as well as a male of the seemingly widespread species Triplectides australis. These 11 new species are here described and illustrated, and a key to males of the New Caledonian Triplectides species is provided. The new species are: T. mouiensis, new species; T. abnormalis, new species; T. minutus,new species; T. noumeiensis, new species; T. tigrinus, new species; T. koghiensis, new species; T. wardi, new species; T. nathaliae, new species; T. mariannae, new species; T. dawnae, new species; T. aequalichelatus, new species. Fifteen species within the genus are now known from New Caledonia; relative to land mass, this is a high diversity compared to the 25 species recorded from Australia.References
