The genus Xanthogramma Schiner, 1861 (Diptera: Syrphidae) in southeastern Europe, with descriptions of two new species

Abstract

Examination of 122 specimens of Xanthogramma Schiner, 1861 (Diptera: Syrphidae) from varied localities in Europe (+Turkey) resulted in the description of two new species (X. aeginae Ricarte, Nedeljković, and Vujić new species and X. pilosum Nedeljković, Ricarte, and Vujić new species), as well as new data on six other species. Most of the examined material originated from the Balkan Peninsula and Greek islands. New species concepts were supported by morphological and molecular evidence. Relationships among the eight studied species were analysed and discussed based on the data of nuclear (ITS2) and mitochondrial (COI) genes sequences. An identification key to the European species of Xanthogramma is provided. Lectotypes are designated for Doros decoratum Zetterstedt, 1843, Lasiophthicus novus Rondani, 1857, Syrphus laetus Fabricius, 1794, Syrphus ornatus Meigen, 1822, and Xanthogramma nobilitatum Frey, 1946.
