SPECIES OF THE GENUS APROCEROS MALAISE, 1931 (HYMENOPTERA: ARGIDAE) OF THE RUSSIAN FAUNA: MOLECULAR GENOTYPING RESOLVES MORPHOLOGICAL PROBLEMS

Species of the small genus Aproceros Malaise in Russia are examined. Illustrated redescriptions of species, including detailed structures of the genitalia, are provided. Variability of the morphological characters and seasonal dimorphism are discussed. The taxonomic status of populations from different parts of the range, as well as the presence of various colour forms, are clarified based on molecular data including two mitochondrial and one nuclear genes. One species, Aproceros hakusanus Togashi, is excluded from the Russian fauna. The distributions of A. leucopoda Takeuchi and A. pallidicornis (Mocsáry) in Russia are clarified. An illustrated key to Russian species of the genus Aproceros and their forms is proposed, and the new data on the phenology of these species across different regions of Russia are provided.
