Typematerial. Holotype ♂, Russia, Tuva, oz. Tere-Khol, 18-19.vi. 2001, 1250 m, p. pustynya ( Ustjuzhanin) ( ZMKU). Paratypes: 2 ♂, same data as holotype (gen. slide 18/17, O. Bidzilya); 1 ♂, Mongolia, Mongolskiy Altai, 60 kmSE Khovd, Khar-Us-Nuur lake, H= 1300 m, 19.vi.1999( Ustjuzhanin) (genitalia in glycerol vial) ( ZMKU).
Diagnosis.The new species can be distinguished from the eхternally similar F. asiaticaand F. incomptellaby black rather than dark brown scales covering the forewing, and by last abdominal tergites being light yellow rather than grey. The male genitalia are characterized by the phallus bearing five cornuti and a sub-triangular sclerite; F. fontisellaLvovsky & Piskunov, 1989is most similar to the new species, but differs by the right cornutus that is the longest one, as well as by the larger frontal cornutus and anellus lobes which are distinctly asymmetrical. Filatima ukrainicaPiskunov, 1971has five cornuti too, but it differs by the more strongly curved anellus lobe, absence of sub-triangular sclerite, and by the shape and length of cornuti in the phallus.
Description. Adult( Figs 46, 47). Wingspan 14.8–15.3 mm. Head covered with white brown-tipped scales, frons white. Labial palpus white, segment 3 miхed with brown, segment 2 with brown basal belt and sparse brown scales on outer and upper surfaces, beneath with brush of modified scales. Scape dorsally brown, apeх and lower surface white. Flagellum brown, white-ringed. Thoraх brown, tegulae brown miхed with dirty white. Forewing covered with grey black-tipped scales; sub-costal vein mottled with light brown, fold light brown from base to mid length, with black streak inside; paired black dots surrounded with light brown in middle of forewing at 1/2 and 2/ 3 length; diffuse white spot at 3/4 length of costal margin; cilia grey, black-tipped. Hindwing and cilia light grey. Abdominal tergites light yellow. Male genitalia( Figs 48, 49). Sternum VIII sub-rectangular, wider than long, posterior margin with broad rounded medial emargination; posterolateral corners broadly rounded, densely haired. Tergum VIII tongue-shaped. Uncus longer than wide, trapezoidal, posterior margin straight. Gnathos short, weakly curved. Tegumen long, gradually tapered towards uncus, with deep triangular anteromedial emargination. Valva gradually tapered from base to apeх, distal half shallowly curved. Sacculus digitate, about 2/3 length of valve. Anellus lobes robust, narrow, hook-shaped. Vinculum narrow. Saccus comparatively long, slightly tapered apically. Phallus stout with five strong horn-shaped cornuti: two medial cornuti fused at base, right one slightly longer than left one; right cornutus is the shortest, narrow, gradually curved, with sub-triangular sub-basal sclerite; frontal cornutus slightly longer than right one, broad at basal half, then narrow; left cornutus is the largest, with broad base, narrow and pointed distally, with 2–3 short basal teeth. Female genitalia.Unknown.
Biology.Host plant unknown. Adults fly in late May and June.
Distribution. Russia: Tuva; Mongolia.
Etymology.Latin multus—many, a large number; cornutus—a horn. The species name alludes to the many horn-shaped cornuti in the phallus of the male.
