Material. Holotype, male, Uzbekistan, Surkhandariya Reg., Babatag Mt. Range , near Zarkomar vill., 26.v.2003, 1000 m, leg. S. Nikiforov, slide AN 039 ( ZISP).

Paratypes. 1 male, Tajikistan, Babatag Mts. , Dzhartepa, 30.vi.2003, leg. V. Shablya ( RYB) .

Description. Male. Length of fore wing 18 mm in holotype, 16−18 mm in paratypes. Thorax and abdomen densely covered with light-brown scales. Antenna about1/2 of fore wing in length, bipectinate (setae three times longer than antenna stem in diameter). Fore wing light-grey, with sputtering of brown scales along costal edge and basally, poorly noticeable black stroke at top of discal cell, fringe mottled, brown at veins, light-grey between veins. Hind wing light-grey, without pattern, border thin, light-brown, fringe light-grey.

Male genitalia. Uncus tapered, smoothly narrowing from base to apex; gnathos arms thin, of medium length, gnathos of medium size, poorly structured; valve narrow, distal third membranous, apex lanceolate, costal edge of valve (on border between medium and distal thirds) with small semicircular process; transtilla process short, with very thick basis, sharply narrowing to apex, serrated in distal third, apex curved, acute; juxta tiny, saddle-like, with pair of short, leaf-like lateral processes, diverged at right angle; saccus semicircular, small; phallus relatively short (3/5 of valve in length), thin, slightly curved and narrowing in distal third, vesica aperture about 1/4 of phallus in length, vesica without cornuti.

Female unknown.

Diagnosis. All the species of this group are very similar externally; in the male genital structure the new species is close to S. stchetkini , from which it differs in a series of characters:

- the lighter color ( S. stchetkini is colored slightly darker);

- the almost complete reduction of the wing pattern ( S. stchetkini , has a developed thin black reticulated pattern on the fore wing);

- the more narrow uncus (in S. stchetkini , the uncus is thicker, apex trapezoidal);

- the thin arms of the gnathos (in S. stchetkini , the gnathos arms are thicker);

- the almost straight phallus, slightly curved in distal third (in S. stchetkini , the phallus is curved in medium third).

Distribution. Tajikistan and Uzbekistan (Babatag Mt. Range).

Etymology. The new species is named after the well-known ornithologist Dr. Rustam Sh. Muratov (Dushanbe), who provided important assistance in organizing field work in Tajikistan.
