Incurvaria pirinella sp. nov., a new species of the vetulella species-group (Lepidoptera, Incurvariidae) from Bulgaria, with release of DNA barcodes for European species of Incurvaria
IncurvariapirinellaJunnilainen, Kaitila & Mutanen,sp. nov.is described from Bulgaria based on specimens collected by netting and artificial light from several low-elevation localities in Bulgaria. The species is morphologically and genetically most similar toI.triglavensisHauder, 1912. Differences between these two species are present in external appearance and genitalia of both sexes. Additionally,I.pirinellashows a distance of 4.74% to its nearest neighbourI.triglavensisin the standard DNA barcoding marker (COI-5P). We provide preliminary observations of phylogenetic affinities of EuropeanIncurvariaand briefly discuss habitat preferences of some species. All species have distinct barcodes with minimum K2P divergences between species averaging 7.05% (range 1.2–12.8%). A world checklist ofIncurvariaHaworth, 1828 is provided and DNA barcodes for all European species are here released. Finally, we document morphological variation in male genitalia withinI.triglavensisHauder, 1912.
