The genus Chaetopteroides (Trichoptera, Limnephilidae) revised by fine structure analysis of parameres

The sexually dimorphic genus Chaetopteroides with combined chaetopterygini and stenophylacini characters was revised based on the well differentiated female external genitalia and on the diversified parameres of the phallic organ. We have reviewed why paramere diversifies so intensively. Re-diagnosis of genus was prepared and three new species are described: C. kosovarorum Ibrahimi et Oláh sp. n. from Kosovo, C. tunik Oláh sp. n. from Macedonia, and C. veges Oláh sp. n. from Bulgaria
