M. 1910-427’; 6 × 18 mm , print ‘ PARATYPE ♀ │ Nemophora │ ornamentella Kozlov’ (both in NHM ). Diagnosis. Nemophora ornamentella is nearest to N. tanakai Hirowatari, 2007 , from which it differs by the narrow (WLR <0.5) yellow spot in the apical part of the forewing, the absence of sexual dimorphism in the forewing pattern, the absence of the incess on the ventral valvar margin, short anellus and long medial process on transtilla. Description. Male ( Fig. 9 ). FWL 10.2 mm , WLR 0.35. Vertex light brownish yellow; frons pale yellow. PLB 1.0 × vertical eye diameter (1.15 × length of scape), pale yellow. Proboscis pale yellow, base frontally with coppery brown scales. Eyes enlarged, but not touching each other; interocular index 1.0; occipital distance 0.2. Antenna 3.0 × FWL. Scape and base of flagellum (up to 0.7 × FWL) dark coppery brown, distal part of flagellum silver-white. Tegulae and thorax dark coppery brown; dorsum laterally with wide yellow stripes. Forewing ( Fig. 73 ) yellow basally to dark brown apically; internal margin of bright yellow medial band straight, reaches costa at 0.55 × FWL. Yellow band on both sides bordered by dark brown lines and then by lead bands; proximal lead band wider than distal lead band; all borders between bands distinct, with abrupt change of colours. Basal part of forewing bright yellow, with five wide glossy lead longitudinal stripes extending from wing base to 0.45 × FWL. Apical part of forewing dark brown, densely scattered by yellow scales, with large oblique spot linking a middle of distal silver band with wing apex; wing margins glossy bronze. Fringe bronze. Hindwing dark coppery brown; costal area grey; fringe bronze to light brown. Underside of hindwing coppery brown, with pale yellow stripe parallel to costa at wing base and with two bright yellow spots: smaller spot almost rectangular, reaching costa between 0.6 and 0.7 × length of hindwing, and larger spot at wing apex along termen. Legs dorsally coppery brown to bronze, ventrally yellow. Epiphysis at 0.4, not reaching apex of tibia. Abdomen dorsally dark brown, ventrally light ochreous brown. Female ( Fig. 10 ). FWL 8.5 mm . Antenna 1.25 × FWL; basal part of flagellum (0.75 × FWL) densely covered with dark coppery brown semi-erect scales forming fusiform brush; flagellum beyond this brush silver-white. Basal abdominal sternites yellow. Otherwise similar to male. Male genitalia ( Figs. 112 , 144 ). Tegumen onion-shaped, without medial ridge. Socii oval, 1.5 × diameter of phallus. Vinculum 3.1 × length of valva, V-shaped, with slightly convex lateral margins; distal margin medially with wide indentation. Tip of tegumen extends beyond tips of valvae. Ventral margin of valva nearly straight; dorsal margin convex; tip of valva rounded. Valvae not fused to each other. Anellus 0.35 × length of valva. Transtilla with long medial process. Juxta 0.5 × length of phallus, arrow head moderately wide (WLR 0.6), with rounded tip and pointed lateral arms. Phallus equal in length to vinculum; basal 0.7 of phallus almost straight, base narrowly funnel-shaped; apical part thin, tip flattened, with two long and thin processes on dorsal side. Distribution . India ( Meghalaya ). Etymology. The specific epithet is derived from ornamentum (Latin: dress, ornament, decoration) and refers to a colourful appearance of this species.
