Diagnosis. The new species differs from its allies by dull brown colouration, much shorter labial palps compared with other Ortopla  species with short 3 rd segment; by extremely large uncus and large strong scobinated patch on central part of vesica. Externally it resembles O. witti  sp. n., but well differs by brown colouration and by male and female genitalia.

Description. Adult (Figs 10, 11, 26, 27). Wingspan: male 40–42 mm, female 45 mm. Palps much shorter compared with other species, pressed; their 3 rd segment small, about ¼ length of 2 nd, in female longer than in male; palps covered with dense brown-grey scales, mixed with whitish, pale yellow-brown frontally. Tegulae and patagia covered with brown and yellowish scales. Tegulae and patagia covered with dark grey scales, bordered by black. Female coloured somewhat lighter than male, with more distinct wing pattern. Forewing dark brown with blackishbrown pattern. Subbasal line pale, double, bordered with wide dark brown subbasal field; antemedial line double, medial field brown, pale in centre, with blackish indistinct medial shadow and small orbicular; antemedial line double, formed by dark dentate inner and outer lines; reniform as indistinct blackish-brown spot; submedial field greyish-brown, with blackish brown dashes; subterminal line indistinct, pale, outlined by dark brown dashes; terminal line broken for row of streaks. Hindwing dark brown, in basal part yellowish-grey with brown suffusion; subterminal line rather thin, waved, terminal field wide, blackish-brown. Male genitalia. ( Figs 42, 43View FIGURES 42 – 45). Uncus huge, equal to tegumen in length, curved basally and subapically, terminated by sclerotised pointed hook; scaphium strong, with bifurcate extension apically; tegumen broad; twice as long as sacculus; juxta arrow tip-like, narrow basally, broader and rounded apically; transtilla as sclerotised band; valva moderate in width, with parallel margins, slightly curved and rounded apically. Aedeagus moderately large, straight; vesica tubular, tapered apically, medially with strong finely scobinated patch. Female genitalia. ( Fig. 50View FIGURES 46 – 53) Papillae anales moderate, quadrangular; apophyses anteriores and posteriores almost equal in length; antrum small, funnel-like, slightly sclerotised; ductus bursae shorter compared with other Ortopla  species, relatively wide; corpus bursae with rather large bulla in joining with ductus.

Etymology. The species name refers to the shape of uncus in male genitalia.

Distribution. China (Guangxi, Yunnan, Hainan), Nepal (Ganesh Himal, Gorkha, Kanchenjunga Himal), Thailand (Tak); N Laos; N Vietnam, N India (Uttar Pradesh). The species occurs in hilly and montane areas with secondary and primary forests vegetation at elevation 1000–1500 m. Flight period from January to October.
