 Diagnosis. Nemophora kuznetzovi is nearest to N. athlophora (Meyrick, 1912), from which it differs by the smaller size, absence of spots in dorsal half of the yellow (basal) field in forewing, dark frons, light yellowish brown colour of scape and basal part of flagellum, shorter PLB, smaller occipital distance, shape of valva, and valvae fused to vinculum.   
 Description. Male (Fig. 61). FWL 4.8–5.9 mm, WLR 0.36–0.44. Vertex yellow to light ochreous brown; frons glossy, coppery brown to indigo blue. PLB 0.25–0.35 × vertical eye diameter (0.55–0.65 × length of scape), light yellowish brown, with dark brown apical segment. Proboscis light yellowish brown. Eyes enlarged, but not touching each other; interocular index 1.05–1.15; occipital distance 0.15–0.40. Antenna 2.8–3.3 × FWL, with simple inwardly directed pegs. Scape and base of flagellum light yellowish brown, apical part of flagellum brown. Tegulae dark coppery brown; thorax glossy golden. Basal half of forewing (Fig. 88) bright yellow, with small dark brown spot at base of R stem, extending along costa to 0.15–0.20 × FWL, and with two pairs of short brown transverse stripes arising from costa at 0.3 and 0.4 × FWL. Apical half of forewing bronze with slight coppery luster, with a line of dark brown scales separating yellow and bronze parts of forewing, slightly extending towards wing apex at costal margin and at R stem. Fringe bronze to dark brown. Basal 0.3 of hindwing semitranslucent, apical part brown to dark brown; costal area grey; fringe brown to light brown. Legs light yellowish brown; apices of tibiae and of all tarsomeres brown. Epiphysis at 0.6, almost reaching apex of tibia. Abdomen light brown with bronze luster.   
Female unknown.  
Male genitalia (Fig. 110). Tegumen trapezieform; medial ridge almost indistinct. Socii elongate, 1.0–1.3 × diameter of phallus. Vinculum 2.1–2.4 × length of valva, V-shaped, with slightly convex lateral margins; distal margin nearly straight, medially indistinct due to fused valvae. Tips of valvae at about same level as tip of tegumen. Ventral margin of valva forms a sharp angle at about 0.35 × valvar length; dorsal margin almost straight; tip of valva narrowly rounded. Valvae separated from each other by narrow V-shaped gap, which nearly reaches vinculum. Anellus 0.3 × length of valva. Transtilla with long medial process. Juxta 0.75 × length of phallus; arrow head moderately wide (WLR 0.5), with widely rounded tip and short pointed lateral arms. Phallus nearly equal to length of vinculum, almost straight. Distal quarter of phallus semitranslucent, without clearly visible structures; base of phallus narrowly funnel-shaped.  
 Distribution. Vietnam (this study).   
 Etymology. Named after the late Vladimir Ivanovich Kuznetzov (1929–2008), a famous Russian lepidopterologist, who collected the holotype.
