Coleophora cytisicolella sp. nov., a new species (Lepidoptera, Coleophoridae), from Austria and Hungary bred from Chamaecytisus austriacus

We describe <i>Coleophora cytisicolella</i> <b>sp. nov</b>. (Lepidoptera: Coleophoridae), a new species from material collected in Austria and Hungary during recent fieldwork. The collected specimens were found only in these countries within the Pannonian Biogeographical Region, and were exclusively associated with <i>Chamaecytisus austriacus</i> (L.) Link (Fabaceae). The taxonomic status of the new species was determined by applying traditional macro- and micromorphological methods and genetic analysis, including genitalia examinations and DNA barcoding (cytochrome <i>c</i> oxidase subunit I). In addition to the results of morphological comparisons and genetic analysis, we present further information on the habitat, life history, and larval food plant of this species. Our results revealed that the examined individuals belong to a species new to science, which is a member of the <i>Coleophora genistae</i> Stainton, 1857 species group, and described here as <i>C. cytisicolella</i> <b>sp. nov</b>. Based on the molecular results, the closest relative of the new taxon is <i>Coleophora bruttia</i>, a species described from southern Italy. Although the examined barcoding sequence poorly differentiated these taxa, the micromorphological features of the genitalia revealed their separate status.
