Material examined RUSSIA : 1 ♁, Altai Republic , Turochak district, 30 km SW of Iogach, 51°31′ N , 87°23′ E , 1600 m a.s.l., 21 Jun. 2003 , V . Sorokina leg. ( SZMN ). Distribution East Palaearctic: China ( Hebei , Shanxi ), Russia ( Altai Mts). East Asian mountain species. Remark In view of the distribution of other species of this group, we can assume that this species also lives in the arctic zone. Table 2. Estimates of evolutionary divergence between studied species of Spilogona Schnabl, 1911 . The number of base substitutions per site from averaging over all sequence pairs between groups are shown. The analysis involved 16 nucleotide sequences. 1 2 3 4 5 1 S. alticola (Malloch, 1920) 2 S. contractifrons (Zetterstedt, 1838) 0.006 3 S. arctica (Zetterstedt, 1838) 0.018 0.018 4 S. imitatrix (Malloch, 1921) 0.046 0.039 0.039 5 S. nitidicauda (Schnabl, 1911) 0.057 0.051 0.053 0.016 6 S. platyfrons Sorokina, 2018 0.055 0.049 0.049 0.012 0.004
