Gnophopsodos ravistriolaria ravistriolaria ( Wehrli, 1922)

(adults Pl. 2, Fig. 6 a; male gen. Pl. 4, Fig. 6 d)

Gnophos ravistriolaria Wehrli, 1922 , Deutsche Entomologische Zeitschrift Iris , 36: 23, pl. 1, fig. 23, pl. 2, fig. 35, 51.— Locus typicus: Russia / Mongolia, Sajan Mountains , Munko –Sardyk, 3400 m. Deposition of holotype: ZFMK. Examined.

Material examined. Type material. Holotype Ƌ of Gnophos ravistriolaria ravistriolaria Wehrli, 1922 (Pl. 2, Fig. 6 a; Pl. 4, Fig. 6 d): [ Russia / Mongolia:] ‘ Munko Sardyk | Sajan mont.’, ‘ ravistriolaria | Wehrli | Gnophos | Dr. Wehrli Ƌ Type’, ‘ ravistriolaria | Wehrli | Gnophos | abgebildet Seitz IV | SupPl. Fig. | Dr. Wehrli Typ’, ‘582 | Ƌ’, ZFMK.

Description. Adults (Pl. 2, Fig. 6 a).

Measurements. Wingspan: 30 mm (Ƌ); forewing length: 16 mm (Ƌ); forewing width: 10 mm (Ƌ). Wings. Upper side yellowish, densely cluttered with gray freckles, especially near margin; postmedial line slightly visible, blurring with freckled background; underside blurred yellowish, a shade lighter than the upper side.

Male genitalia (Pl. 4, Fig. 6 d). [The description of the male genitalia is given based on the remaining fragment of the valva and the photograph of the holotype depicted by Wehrli (1922)] Costa with costal thorns condensed on a subterminal cactus-like structure; uncus strongly sclerotized, terminating in a beak-like peak.

Diagnosis. Gnophopsodos ravistriolaria ravistriolaria can be recognized by its rounded forewings and its blurred brownish wing-pattern.

Distribution ( Fig. 4 ). The type specimen of G. ravistriolaria ravistriolaria was captured in the Sajan Mountains at Munko–Sardyk at an altitude of 3400 m. The mountain Munko–Sardyk is located north of the lake Chöwsgöl Nuur near the Russian–Mongolian border. Viidalepp & Soljanikov (1977) figured a male from river Horidulin–Gol and listed a female from upper course of river Uryngym–Gol but we did not succeed in finding the exact sites of these on maps.

Biology. After Viidalepp & Soljanikov (1977) a female was captured on the 6th of July 1965 and a male on the 19th of August 1966.
