Diagnosis. Nemophora costimaculella is closest to N. athlophora ( Figs. 64‒66 View FIGURES 63–68 ), from which it differs by the seven glossy golden spots in the basal half of the forewing, which are almost indistinguishable from the yellow background, and by the presence of carinae on phallus. From N. chrysidias ( Fig. 63 View FIGURES 63–68 ) N. costimaculella differs by the V-shaped vinculum, the absence of deep indentation on the ventral valvar margin and the absence of anchor-shaped structure at the tip of phallus.
Description. Male ( Fig. 67 View FIGURES 63–68 ). FWL 5.8–6.9 mm, WLR 0.35–0.40. Vertex with sparse piliform scales that are pale yellow above antennal sockets and light brown along occipital margin; frons light golden, coppery iridescent, with a row of relatively short yellow piliform scales below antennal sockets. PLB 0.4–0.5 × vertical eye diameter (1.0‒1.1 × length of scape), light yellowish brown, with very few raised piliform scales. Proboscis light brown. Eyes enlarged, but not closely approaching each other; interocular index 1.2–1.3; occipital distance 0.20–0.25. Antenna 3.1–3.4 × FWL. Scape and 3–7 basal flagellomeres ochreous brown, then colour of flagellum turns to bronze. Tegulae proximally glossy golden, distally coppery bronze; thorax light glossy golden. Basal half of forewing ( Fig. 108 View FIGURES 93–108 ) bright yellow; apical half (separated by dark coppery brown band) dark bronze. Basal half of forewing with a narrow dark brown costal stripe at the wing base reaching 0.15 × FWL, and seven glossy golden spots: one spot at the wing base below the costal spot, three spots forming proximal interrupted band reaching costa at 0.25 × FWL, and another three spots forming distal interrupted band reaching costa at 0.40 × FWL; spots adjacent to costa are laterally bordered by dark coppery brown scales. External margin of dark coppery brown transverse medial band forms two lateral protuberances near costa. Fringe dark bronze. Hindwing brown, distal half with coppery iridescence; costal area light yellow; fringe bronze to light yellowish brown. Legs (femurae and tibiae) coppery bronze to light bronze; tarsomeres pale yellow; apices of all tarsomeres light brown. Epiphysis at 0.6, almost reaching apex of tibia. Abdomen dark bronze to coppery brown.
Female ( Fig. 68 View FIGURES 63–68 ). FWL 5.0– 5.4 mm, WLR 0.45–0.50. Antenna 2.1–2.4 × FWL, with short black brush at about 0.5–0.6 × FWL. Otherwise similar to male.
Male genitalia ( Figs. 139 View FIGURES 134–139 , 169 View FIGURES 167–169 ). Tegumen trapeziform, with flat tip. Socii oval, 1.8 × diameter of phallus. Vinculum 2 × length of valva, V-shaped, with straight margins. Tips of valvae slightly extend beyond tip of tegumen. Ventral margin of valva basally (until 0.4 × length of valva) straight, then bent; distal part with slight indentation; dorsal margin slightly concave; tip of valva narrowly rounded. Valvae not fused to each other. Anellus 0.5 × length of valva. Transtilla with extremely long medial process. Juxta 0.55 × length of phallus; arrow head extremely wide (WLR 0.85), with widely rounded tip and short pointed lateral arms. Phallus of about same length as vinculum, almost straight; apical third developed into flat lobe with pointed tip; two horn-like processes (0.15 × length of phallus) arise at the base of this lobe. Base of phallus widely funnel-shaped.
Distribution. India (Meghalaya), Thailand.
Etymology. The specific epithet is derived from costa (Latin: rib, side) and macula (Latin: spot) and refers to characteristic traits of forewing pattern.
Comments. Although Walsingham clearly labelled a holotype of ‘ Chrysobasis costimaculata ’, the description has never been published.
