Diagnosis. Adult ( Figs 37, 38 ). Wingspan 46–47 mm. T. nekrasovi can be recognized by brown ground colour of forewing with back waved transversal lines and intensive dusting of white and blackish scales along veins, and, especially in costal area; the cell between orbicular and reniform filled with black, orbicular small, rounded, reniform indistinct; subterminal line broad, in upper part of wing diffused; terminal field brown, crossed by blackish and white veins. Hindwing yellow, with intensive blackish dusting in basal area and well defined brownish-black terminal band.

Male genitalia ( Fig. 102 ). The genitalia armature of T. nekrasovi is most similar to T. helmuti , but differs by rather narrow uncus, not extended apically, stronger harpe and by the shape of vesica formed with subapical and apical diverticula armed with patch of rate fine cornuti and small patch of moderate cornuti. Uncus moderate long, rounded, relatively narrow; tegumen moderate broad, about half length of vinculum, with small penicular extensions; vinculum V-shaped, narrow; transtilla with moderate broad lobes; juxta shield-like, broad; valva moderate large, slightly curved distally, with parallel margins in basal half, constricted from mid-part and rounded in the apex; harpe lies in distal third of valva, large, massive, curved; not extends distal margin of valva. Aedeagus large, slightly curved medially; carina broad, sclerotised, finely scobinate; vesica broadly-tubular with two subapical diverticula; bigger diverticulum bearing small patch of moderate cornuti, smaller one armed with rare fine cornuti.

Female unknown.

Distribution and bionomy. China (Prov. Shaanxi). The species occurs at elevation 1500–1900 m. Moth flies in June, August and September.
