Nemophora ceylonella differs from all Nemophora species recorded in India and Sri Lanka by its extremely small size (male FWL 3.8 mm ). This species externally resembles N. scitulella ( Figs. 41, 42 ), from which it differs by the large brown costal spot in the yellow basal part of the forewing, short medial process of transtilla and the hook-shaped apical part of phallus. Description . Male ( Fig. 40 ). FWL 3.8 mm , WLR 0.41. Vertex pale yellow to light brown; frons glossy golden. PLB 0.2 × vertical eye diameter (0.6 × length of scape), light brown. Proboscis brown, base with a few golden scales. Eyes enlarged, but not touching each other; interocular index 1.7; occipital distance 0.36. Antenna 3.4 × FWL; pegs present. Scape and flagellum light brown with bronze tint; basal 25‒30 flagellomeres with dark brown rings; Tegulae and thorax glossy golden. Basal 0.25 × FWL pale yellow, with large brown costal spot; apical 0.75 × FWL dark coppery bronze ( Fig. 92 ). Fascia narrow, 0.07 × FWL at both costa and dorsum; consists of pale yellow band, which reaches costa at 0.4 × FWL; external margin of this band protrudes apically to 0.6 × FWL. Fringe dark brown to brown, apically with golden lustre. Hindwing dark coppery brown; costal area grey; fringe brown. Legs light brown; apices of all tibiae coppery brown; tarsomeres coppery brown with yellow apices. Epiphysis at 0.5, almost reaching apex of tibia. Abdomen brown; distal margins of pregenital sternites light yellowish brown. Female unknown. Male genitalia ( Fig. 124 ). Tegumen onion-shaped. Socii almost round, 1.3 × diameter of phallus. Vinculum 3.3 × length of valva, V-shaped, with almost straight lateral margins; distal margin gently W-shaped. Tip of tegumen extends beyond tips of valvae. Valvae fused basally to 0.3 × length of valva; their internal margins indistinct. Ventral margin of valva with a lobe reaching 0.8 × length of valva; dorsal valvar margin straight; tip of valva rounded. Anellus 0.5 × length of valva. Transtilla with short medial process. Juxta 0.45 × length of phallus; arrow head moderately wide (WLR 0.50), with pointed tip and short pointed lateral arms. Phallus 0.8 × length of vinculum, shallowly S-shaped; tip flat, wide, hook-shaped; base narrowly funnel-shaped. Distribution. Sri Lanka . Etymology . The species is named after a historical name of Sri Lanka ( Ceylon ). Comments . Metathorax with hind wings is kept in gelatine capsule pinned under the specimen.
