Abstract:

The taxonomy and systematics of the New Caledonian endemic caddisfly genus Gracilipsodes Sykora, 1967 (Trichoptera: Leptoceridae: Grumichellini) are reviewed. Seven new species represented by males are described and illustrated: Gracilipsodes aoupiniensis sp. nov., Gracilipsodes aureus sp. nov., Gracilipsodes aurorus sp. nov., Gracilipsodes grandis sp. nov., Gracilipsodes koghiensis sp. nov., Gracilipsodes lanceolatus sp. nov., and Gracilipsodes robustus sp. nov. Molecular phylogenetic analyses are applied to discern the relationships among the species of the genus and their closest relatives, based on sequence characters from the nuclear gene translation elongation factor-1α (EF-1α) and the three mitochondrial genes cytochrome oxidase I (COI), COII, and ribosomal large subunit (16S). The data are analyzed using parsimony and Bayesian inference, revealing a monophyletic Gracilipsodes with the eastern Australian monotypic genus Triplexa as its closest relative. Gracilipsodes is in turn divided into two major lineages. © 2008 The Linnean Society of London, Zoological Journal of the Linnean Society, 2008, 153, 425-452.
