Variability. Disc of the pronotum can be with elongate puncturation on sides.

Distribution. Turkmenistan (Karakum desert), Uzbekistan (Karakum and Kyzylkum deserts, sands of Amudarya delta) ( Medvedev & Nepesova 1985a; Bekchanov et al., 2023; ZIN collection), NW Afghanistan (Kushka) ( Gridelli 1954, Kaszab 1959, 1966, ZIN collection), Kazakhstan (Kyzylkum, Muyunkum, Ili River) (ZIN collection). The record of this species for Tien Shan ( Kyrgyzstan: Naryn) ( Gridelli 1954) is very doubtful.
