Description — Male: Wingspan 38-40 mm, length of fore wing 17-18 mm. Head small, eyes large, globular, densely hairy, palpi very short, porrect, blackish laterally, proboscis rather short. Frons smooth, antenna broadly bipectinate, slightly asymmetrically with longer branches on dorsal side, especially in basal half; final segments biserrate, axis of antenna brown, dorsal surface covered with whitish scales. Vestiture of head and thorax rather homogeneous, long, hair-like scales, dark ash-grey mixed with pinkish and red-brownish hairs, abdomen somewhat browner with reddish lateral ridges, dorsal crest absent. Legs reddish-ochreous, tibial spurs short, obtuse. Fore wing elongate, with apex rather acute, outer margin evenly arcuate. Ground colour dark, slightly ochreous ash-grey, with weak pinkish-reddish and dark grey irroration, medial area suffused variably strongly with reddish-brown scales. Antemedial line obsolescent or relatively weak, simple, dark grey, more or less straight, slightly waved, postmedial line rather sharply defined, strongly sinuous, dark grey, marked with blackish dots on veins. Median fascia broad, diffuse, upper half shadow-like or deleted, lower part usually stronger, reddish brown. Orbicular and reniform stigmata present, encircled with fine reddish and ochreous lines, lower quarter (sometimes most parts) of reniform filled also with plumbeous scales. Claviform absent or obsolete, defined mostly by its paler greyish ground colour. Upper part of subterminal line relatively strong, whitish-ochreous, defined with reddishbrown spots, lower parts obsolete or missing. Terminal line pale ochreous, cilia as ground colour, apical part often more reddish. Hind wing shiny whitish-ochreous, irrorated with brownish grey, veins covered with brown, discal spot present, round, transverse line absent. Terminal line rather diffuse, greyish, cilia pinkish-ochreous. Underside of both wings ochreous-whitish, inner areas of fore wing suffused with pale greyish, discal spot strong, upper part of transverse line marked with blackish spots on veins. Hind wing irrorated sparsely with dark grey-brown, discal spot strong, rounded, transverse line represented by fine dots on veins. Female: Somewhat smaller in size, with slightly shorter fore wing, antenna shortly bipectinate, otherwise sexes similar. Male genitalia (Fig. 8): Uncus short, slender, with apex pointed, tegumen narrow, relatively high, penicular lobes very narrow. Fultura inferior rather small, heavily sclerotized, shield-like, transtilla also heavily sclerotized, vinculum long, strong, V-shaped. Valva elongate, medial part strongly dilated, slightly asymmetrically, left valva somewhat broader. Cuculli small, bird-head-like, also slightly asymmetrical, lateral process longer on left valva, apex acute, corona absent. Costa heavily sclerotized, with strong, rounded lobe at medial third. Sacculus broad, strong, setose, distal ends partly heavily sclerotized, clavi reduced. Pulvillus (editum) short, bar-like, densely setose with long, strong setae. Erect parts of harpes also slightly asymmetrical, flattened, rounded quadrangular, more elongate on left valva. Ampullae long, strong, thick, falciform with apices acute. Aedeagus rather long, cylindrical, carina sclerotized, with rounded, dentate ventro-lateral plate on left side, and with two long, flattened dorsal laminae, left one strongly serrate. Vesica broadly tubular, membranous with fine scobination, everted ventrally, recurved dorso-laterally. Basal part with two small, more or less globular diverticula, medial part with an additional small diverticulum. Distal third with two large terminal diverticula, one armed with a bundle of long, acute, spiniform cornuti. Female genitalia (Fig. 9): Ovipositor short, papillae anales rather weak, apophyses slender; penultimate segment very short, dorsal part half-ring-like. Ostium bursae huge, more or less infundibuliform, heavily sclerotized, with strongly unequal dorsal and ventral plates (dorsal plate much larger), entrance of ostiai complex U-shaped.
