New data on the blackfly fauna (Diptera, Simuliidae) of Southern Altai Mountains in East Kazakhstan
New distribution data for 7 Simulium species of blackflies (Diptera, Simuliidae) in the middle altitudes (1000–2000 m a.s.l.) of the Southern Altai have been obtained. Simulium (Montisimulium) quattuordecimfilum Rubtsov, 1947 is recorded for the first time for the Altai Mountains. A comparative analysis of species distribution of the subgenus Montisimulium is presented for Southern Siberia and adjacent territories. The blackfly fauna of Southern Altai, taking into account the taxonomic changes of Simuliidae [Adler, Crosskey, 2010], is represented by 33 species in 7 subgenera of the genus Simulium.
