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.
