P.N., Kh.N., A.A., E.A. Distribution. Central-Eastern-Palaearctic subboreal range: originally described from Kyrgyzstan, the species is widely distributed in Eurasia, spanning from the Black Sea region in the west through eastern Kazakhstan to Cisamuria in the east ( Titova 1972b ). In Siberia E. retusidens has been known from the Kemerovo Area, Altai Province, and Republic of Altai ( Nefediev et al. 2017a , c , d ). Remarks. In the study area, E. retusidens inhabits both slopes, and is one of the most dominant species.
