 Diagnosis. Forewing length 13.5–15 mm in males (14.5 mm in the holotype). Specimens from Mongolia (Fig. 19) are slightly smaller in size than those from the Russian Altai (Figs 16–18). Athaumasta arida (Figs 16–19) is very similar externally to A. expressa (Figs 35–45) and can be distinguished by the genitalia structures only. In the male genitalia, A. arida (Figs 54, 55) differs from A. expressa (Figs 64– 68) by its longer harpe, slightly longer valva with more massive distal section, and smaller cornutus in vesica. Compared to those of A. kuchinichi (Figs 62, 62), the male genitalia of A. arida have longer harpe and slightly broader vesica. The male genitalia of A. arida are also similar to those of A. siderigera (Fig. 69), but the vinculum is more robust, the ventral margin of valva is less convex, the harpe is slightly shorter, and the vesica is much broader. The moths of A. arida (Figs 16–19) differ clearly from A. siderigera (Fig. 34) by their more robust body and orange or olive green forewing ground color (that is blackish in A. siderigera).   
Female unknown.  
 Molecular data. COI 5‘ sequences of nine specimens of A. arida from three localities were compared with COI 5‘ sequences of eleven specimens of A. expressa from six localities, three specimens of A. kuchinichi from one locality, six specimens of A. tarbagata from two localities and two paratype specimens of A. argillacea from one locality. The infraspecific variation of COI 5‘ sequences of A. arida is 0.00–0.62%; that of A. expressa is 0.00–0.77%. The distance between specimens of A. arida and A. expressa is 4.11–4.99%; that between A. arida and A. kuchinichi is 3.78–4.15%; that between A. arida and A. argillacea 3.62–3.98%; that between A. arida and A. tarbagata is 3.86–4.65%. The COI 5‘ sequences of A. arida are characterized by the combination of two character states unique for the genus, 19(C) and 87(A), and a character state unique for the species-group, 274(T) (Table 3).   
 Distribution. The species is widespread from the Chuya Steppe in the southeastern Russian Altai to the southern part of Mongolian Altai. It inhabits dry stony steppe slopes and semi-deserts at medium altitudes (1700–2300m) (Figs 78, 79).   
 Etymology. The species‘ name refers to its habitat in dry biotopes.
