Description. Adult ( Figs. 1–8 View FIGURES 1–8 ). Forewing length 17–18 mm. Head whitish; palpi porrect, orange-yellow, underside pale, base covered with long hairs. Antennae ciliated, light brown, scape covered with whitish scales. Thorax white with crimson transverse band. Collar with crimson margin, apex of patagia with concolorous scale. Legs orange-yellow on upper side and white on underside; tarsal segments orange-yellow, banded with white. Forewing white; costa orange-yellow, whitish at lobe; sub-basal crimson band, from costa to A 1; antemedial crimson band, forming a sign of interrogation; a rounded black spot in cell, disco-cellular with black spots on upper angle and lower angle; post-medial band crimson, broader below Cu 1, outlined with black scales from below Cu 1 to inner margin, a black irregular sub-costal spot beyond post-medial band; outer area orange-yellow; cilia white. Hindwing pale orange-yellow with costal area and cilia whitish. Abdomen covered with white hairs; anal tuft pale ochreous. Male genitalia ( Figs. 23–26 View FIGURES 23–26 ). Uncus small, tip minutely blunt, in some specimens tip may be swollen. Tegumen broad, longer than uncus. Vinculum as long as tegumen, forming broad, flat u-shape saccus. Valva broad costal edge wavy, apex of cucullus rounded; distal saccular process long, slightly shorter than cucullus, curved sub-apically, tip with a small spine; a small ampulla situated medially. Juxta inverted U-shaped. Vesica broad, with several diverticula; dorsal subbasal diverticulum large, membranous, with several small subdiverticula; three medial diverticula with clusters of strong spinulose scobination and weak granulation; one medial diverticulum membranous; ejaculatorius entering sub-terminally. Female genitalia. Papillae anales almost rectangular, edges rounded; genital plate narrow; apophyses are almost of equal length; ostium bursae broad; ductus bursae short; corpus bursae sac like; a slightly elongated signum present.

Diagnosis. Morphologically, C. neopuer   , sp. nov. belongs to the newly established, the Cyana puer   speciesgroup and is closely similar to C. puer   . Externally, these species have no significant differences and can be distinguished only by the genitalia structure. In vesica of C. neopuer   , only two small medial diverticula have clusters of spinulose scobination and the third medial diverticulum is membranous, whereas, in C. puer   all the three small medial diverticula are armed with clusters of spinulose scobination. In female genitalia, corpus bursae is oval and signum is slightly elongated in C. neopuer   whereas, in C. puer   corpus bursae is slightly elongated and signum is shorter.

Etymology. The new species is named due to its close resemblance with C. puer   .

Distribution. India (Sikkim, Arunachal Pradesh, Meghalaya), Nepal, Myanmar. The species was recorded from altitudinal range of 370 m to 1650 m ( Fig. 35 View FIGURE 35 ).
