Description. Male (Figs. 7, 8). FWL 6.2 ‒ 7.7 mm, WLR 0.36 ‒ 0.40. Vertex glossy golden medially, bordered anteriorly and posteriorly by dark brown piliform scales. Frons glossy golden, bearing a few brown piliform scales below antennal sockets. PLB 0.6 × vertical eye diameter (1.05 ‒ 1.15 × length of scape), covered by light yellowish brown appressed scales. Proboscis light brown. Eyes enlarged, but not touching each other; interocular index 1.4 ‒ 1.6, occipital distance 0.15 ‒ 0.30. Antenna 3.9 ‒ 4.1 × FWL. Scape shining coppery bronze; 8 ‒ 12 basal flagellomeres dark brown, first 3 ‒ 5 of them thickened by raised dark coppery brown scales; distal part of flagellum silver grey. Tegulae and thorax golden. Forewing basally (up to 0.4 × FWL) glossy golden; costal spot at forewing base extends to 0.35 × FWL (Fig. 13). Fascia dark brown, straight, narrow (0.07 × FWL at costa, 0.05 × FWL at dorsum), slightly oblique; inner margin of fascia reaches costa at 0.39 ‒ 0.47 × FWL; costal half of fascia with yellow medial band. Distal part of forewing bronze with coppery iridescence, with two or three yellow spots surrounded by dark brown scales; long axes of these spots parallel to each other. Two of these spots, one touching costa at 0.56 ‒ 0.62 × FWL and another at wing apex, are connected by narrow band of dark brown scales sometimes including yellow line, forming S-shaped figure. Third yellow spot near termen clearly isolated from two other spots. Fringe gold to bronze apically to brown with coppery iridescence basally. Hindwing brown, with slight coppery iridescence; costal area grey; fringe brown. Legs golden proximally to dark coppery brown distally; bases of all tarsomeres pale yellow. Epiphysis at 0.5, reaching (or almost reaching) apex of tibia. Abdomen light brown. Female (Fig. 9). FWL 6.0 ‒ 6.3 mm, wider than in male: WLR 0.42 ‒ 0.46. Antenna 1.5 ‒ 1.8 × FWL; base not thickened. Abdomen brown dorsally, gold to coppery ventrally. Otherwise similar to male. Male genitalia (Figs. 17, 20). Tegumen wide, dome-shaped, with distinct medial ridge. Socii 1.3 × diameter of phallus. Vinculum 1.8 ‒ 2.2 × length of valva, with slightly convex lateral margins and shallowly W-shaped distal margin. Tips of valvae extend beyond tip of tegumen. Ventral margin of valva medially with prominent lobe; dorsal margin with slight protrusion in the middle; tip of valva narrowly rounded. Valvae fused basally up to 0.4 × total length; their internal margins indistinct; base of fused valvae medially with deep, narrow indentation (0.05 ‒ 0.07 × length of valva). Anellus 0.4 × length of valva. Transtilla with short triangular medial process. Juxta 0.6 × length of phallus; arrow head wide (WLR 0.6), with pointed tip and pointed lateral arms; it exceeds half of juxta’s total length. Phallus 1.0 ‒ 1.1 × length of vinculum, in lateral view shallowly S-shaped. Tip of phallus slightly wider than its medial part, with deep ventral incision and small dorsal indentation; base of phallus narrowly funnel-shaped.
