Diagnosis. Nemophora rubicunda externally differs from all Nemophora species known from the study region by the yellow basal part of forewing extending to 0.35 × FWL combined with dark brown transverse spot adjacent externally to this yellow part. In male genitalia N. rubicunda resembles N. costimaculella ( Fig. 62 View FIGURES 57–62 ), from which it differs by the much smaller extent of yellow colour in the forewing base, smaller occipital distance, and greater width of the basal part of valva relative to the apical part of it.

Description. Male ( Fig. 58 View FIGURES 57–62 ). FWL 7.1–7.5 mm, WLR 0.39–0.41. Vertex with tuft of white to pale yellow piliform scales at occipital margin and with dark brown piliform scales above antennal sockets; frons glossy golden, with sparse brown piliform scales below antennal sockets. PLB 0.4–0.6 × vertical eye diameter (0.8–1.1 × length of scape), pale yellow. Proboscis brown. Eyes enlarged, closely approaching occipitally, but not touching each other; interocular index 1.4–1.5; occipital distance 0.04–0.05. Antenna 3.1–3.2 × FWL, with simple inwardly directed pegs. Scape and base of flagellum coppery bronze; at 0.7 × FWL colour of flagellum abruptly changes to grey. Tegulae and thorax bronze. Forewing ( Fig. 86 View FIGURES 63–88 ) glossy, light bronze; basal part yellow, with coppery brown spot at base of costa and glossy golden stripe extending along costa to 0.17 × FWL. Yellow colour along costal margin extends to 0.35 × FWL and reaches triangular dark brown spot, which extends to 0.3–0.4 of forewing width. Apical part of forewing adjacent to outer wing margin sparsely suffused with yellow and dark brown scales. Fringe bronze to brown. Hindwing brown with coppery tint, except for semitranslucent anal field; costal area white; fringe brown. Femora and tibiae of fore and mid legs dark coppery bronze, of hind legs yellowish brown, darker distally; tarsomeres light brown to light bronze. Epiphysis at 0.45, almost reaching apex of tibia. Abdomen bronze.

Female unknown.

Male genitalia ( Figs. 108 View FIGURES 106–110 , 122 View FIGURES 122–123 ). Tegumen dome-shaped, with prominent medial ridge. Socii elongate, 1.3 × diameter of phallus. Vinculum 3.0 × length of valva, V-shaped, with slightly convex lateral margins; distal margin medially with pointed protuberance. Tip of tegumen extends beyond tips of valvae. Basal 0.6 of valva wide, forming posteroventrally directed lobe; dorsal margin almost straight; tip of valva rounded. Valvae fused basally at 0.4 × total length; internal margins distinct. Anellus 0.5 × length of valva. Transtilla with long triangular medial process. Juxta 0.5 × length of phallus; arrow head moderately wide (WLR 0.55), with widely rounded tip and short pointed lateral arms. Phallus nearly equal to length of vinculum, almost straight, with two gently C-shaped carinae articulated to its ventral side at 0.7 × length of phallus (counting from its base). Distal part of phallus consists of short dorsal lobe (reaching same level as apices of carinae) and long ventral lobe; base of phallus narrowly funnel-shaped.

Distribution. Myanmar (this study), Thailand (this study; photograph-based record: https://www.inaturalist. org/observations/136227026), Indonesia (this study).

Etymology. The specific epithet is derived from rubicunda (Latin: suffused with red, ruddy) and refers to a diagnostic trait in forewing pattern.

Comments. Although Walsingham labelled one of paratypes as the type of Nemotois rubicunda , he never published the description of this species.
