Diagnosis. External characters: A. golomto sp. n. is a sister species of the recently described A. pekarskyi. Externally, the new species (Figs 1–5) differs from A. pekarskyi (Figs. 6–8) in the forewing ground color varying from ochreous yellow to reddish ochreous (while in pekarskyi the forewing coloration is dark grey with ochreous suffusion), and a more contrasting pattern. The forewing pattern of A. golomto sp. n. is also similar to that of A. splendida O. Bang- Haas 1927 (Figs 9, 10), which belongs to a different species-group, but A. golomto sp. n. can be distinguished by the more robust body and larger reniform stigma. Genitalia. The male genitalia of A. golomto sp. n. (Figs. 11, 12) are very similar to those of A. pekarskyi (Figs. 13, 14), but differ in the slightly narrower uncus, and the curved harpe (while in pekarskyi the harpe is almost straight); golomto differs from A. splendida (Figs. 15, 16) in the shorter and distally narrower valve, the slightly broader vesica, and the absence of a cornutus in the vesica. The female genitalia of A. golomto sp. n. (Fig. 17) differ clearly from those of A. pekarskyi (Fig. 18) in the longer apophyses anteriores and posteriores, the significantly narrower and shorter antrum, and the narrower and shorter sclerotized anterior section of the ductus bursae; from A. splendida (Fig. 19) they differ in the slightly longer apophyses anteriores and posteriores, the narrower and longer antrum, and the shorter sclerotized anterior section of the ductus bursae. COI 5' Mitochondrial COI 5' DNA: Athaumasta golomto sp. n. can be diagnosed from sequenced A. pekarskyi and A. pekarskyi specimens by the following unique combination of six character states: 22(G), 208(G), 238(T), 268(C), 364(C) and 586(T), while Athaumasta pekarskyi is characterized by the unique combination of nine character states: 86(G), 130(G), 220(T), 317(A), 385(C), 400(T), 542(T), 548(C) and 589 (C) (see Table 2).

Molecular data. The male genitalia of A. golomto sp. n. and A. pekarskyi are very similar, therefore COI 5’ sequences of three specimens of A. golomto sp. n. from two localities in SW Mongolia (Mogoijn-Gol valley—DNA vouchers ## AV-0064-Noct and AV-0067-Noct, and Adzh-Bogd-Uul Mts.—DNA voucher AV-0062-Noct) were compared with COI sequences of two A. pekarskyi specimens from two localities in the Altai Mts: a paratype specimen from the type locality (vicinities of Aktash village, DNA voucher AV-0061-Noct) and a paratype specimen from vicinities of Kurai village (DNA voucher AV-0062-Noct) (see Table 1). The paratype specimens of A. pekarskyi have identical COI 5’ sequences. The paratype specimens of A. golomto sp. n. from Mogoijn-Gol valley also have identical COI 5’ sequences, and distance between them and the paratype specimen from Adzh-Bogd-Uul Mts. is 0.15%. The distance between the paratype specimens of A. golomto sp. n. from Mogoijn-Gol valley and the paratype specimens of A. pekarskyi is 2.49%. The distance between the paratype specimen of A. golomto sp. n. from Adzh-Bogd-Uul Mts. and the paratype specimens of A. pekarskyi is 2.33%. In addition, the COI 5’ sequences of A. golomto sp. n. were compared with those of three specimens of A. splendida (DNA vouchers AV-0063-Noct, AV-0065-Noct and AV-0066-Noct) from two localities in SE Russian Altai. The distance between the paratype specimens of A. golomto sp. n. from Mogoijn-Gol valley and the specimens of A. splendida is 4.59%, distance between the paratype specimen of A. golomto sp. n. from Adzh-Bogd-Uul Mts. and the specimens of A. splendida is 4.75%.
Description. Adult (Figs 1–5). Forewing length 13.5– 16 mm in males and 15–16 mm in females. Male antennae bipectinate, female antennae filiform. Head, patagia, thorax and tegulae ochreous yellow or orange ochreous. Abdomen dark brown with ochreous scales. Forewing moderately broad, apex slightly elongated, apically rounded; outer margin evenly curved with slightly oblique tornus. Ground colour ochreous yellow or orange ochreous, irrorated with grayish scales which sometimes can dominate (Fig. 3); wing pattern well developed; basal field as ground colour. Transversal lines double: subbasal, postmedial and subterminal lines blackish inwardly and whitish outwardly, antemedial line whitish inwardly and blackish outwardly; subbasal line dentate, antemedial line irregularly wavy, postmedial line Sshaped curved, dentate on veins, subterminal line sinuous, discontinuous; terminal line as row of blackish dots on veins. Reniform and orbicular stigmata as ground colour, with whitish margins; claviform stigma as broad, rounded stroke, as ground color, with whitish margins, diffuse, often poorly developed. Cilia ochreous yellow or orange ochreous with blackish spots on veins. Hindwing pale ochreous creamy, with strong grey suffusion; discal spot dark grey, elliptical; two broad and diffuse, gray, wavy transverse lines; cilia grayish brown. Male genitalia (Figs 11, 12). Uncus slender, dorsoventrally flattened, slightly curved, medially broadened, with pointed apex; tegumen relatively short compared with valves, penicular lobes rounded; transtilla broad, obtuse apically; juxta ovate, shield-like; valva elongate, basally broadened, narrowed distally, slightly broadened subapically, with pointed apex; costal margin of valva slightly curved medially, dorsal margin slightly constricted at middle; clasper moderately long, distally broadened, S-shaped; harpe elongate, evenly curved, narrowed distally, with pointed apex, sometimes with a rectangular protrusion subbasally. Aedeagus cylindrical, distally curved, with scobinate carinal plate; vesica saccular, membranous, finely scobinate, its basal section broad, globular, curved ventrally, distal tube elongate and narrow. Female genitalia (Fig. 17). Ovipositor short, broadly conical; papillae anales trapezoidal, with rounded edges; apophyses anteriores and posteriores of equal length, elongated and thin, as long as 8 th abdominal segment; antrum broadly funnel-like, heavily sclerotized; ductus bursae as long as antrum, its posterior section membranous, anterior section heavily sclerotized; corpus bursae sack-like, membranous; appendix bursae situated postero-laterally, broadly conical.
Distribution and bionomics. The new species is known from West Mongolia (southern part of Mongolian Altai Ridge and Adzh-Bogd-Uul Ridge) and NW China (Xinjiang, Chinese Altai Mts.). Athaumasta golomto sp. n. inhabits dry rocky slopes at altitudes 1250–2500 m. Moths are on wing in June–July.
Etymology. In Mongolian mythology Golomto (or Golomt Eezh) is a goddess, a keeper of the family hearth and a patron of all mothers.
