Diagnosis. Nemophora chalcoptera is similar to N. paradisea ( Figs. 32 View FIGURES 25–32 , 33 View FIGURES 33–40 ) and N. decisella ( Figs. 34, 35 View FIGURES 33–40 ), from females of which it differs by the glossy bronze dorsal part of forewing base, absence of the internal glossy band in forewing fascia, presence of diffuse dark brown spot at the outer forewing margin and of large yellow spot at the middle of costal hindwing margin. This species also resembles N. nigripunctella ( Fig. 30 View FIGURES 25–32 ), from which it differs by the large size, wide yellow band of fascia and presence of transverse yellow spot in hindwing.

Description. Male unknown.

Female ( Fig. 31 View FIGURES 25–32 ). FWL 7.4–7.7 mm, WLR 0.38–0.40. Vertex pale yellow; frons marginally ochreous brown, medially naked. PLB short, light ochreous brown; apical segment dark brown. Proboscis brown. Antenna 1.6 × FWL. Scape and basal part of flagellum (up to external margin of yellow band in forewing fascia) dark coppery bronze, slightly thickened by semi-erect scales; apical part of flagellum light brown. Tegulae and thorax glossy bronze with coppery tint. Basal part of forewing ( Fig. 77 View FIGURES 63–88 ) bronze, with small dark brown spot at base of R stem. Bright yellow band of fascia wide (0.20–0.25 × FWL along costal margin); its inner margin reaches costa at 0.28–0.30 × FWL. This yellow band on both sides is bordered by 1–2 rows of dark brown scales. On external side (but not on internal one) this line is followed by narrow (0.03–0.04 × FWL) glossy bronze band and then by diffuse dark brown band of about same width. Apical part of forewing coppery brown, with diffuse dark brown spot at outer margin. Fringe dark coppery brown. Hindwing brown; costal margin medially with large yellow spot extending to 0.5 × hindwing width; R and M1 stalked; fringe brown at apex to grey at wing base. Fore legs dark brown except for pale yellow first tarsomere; mid and hind femora brown, tibiae brownish yellow with dark brown tips; tarsi dark brown. Epiphysis at 0.6, short, not reaching apex of tibia. Abdomen brown to bronze; distal margins of sternites pale yellow.

Distribution. Laos (this study).

Etymology. The specific epithet is derived from chalkos (χαλκος, Greek: copper) and pteryx (πτέρυξ, Greek: wing) and refers to the colour of distal part of forewing.
