Diagnosis. Differs from other Ortopla species by more robust body, wings dark blackish-brown with grey, wing pattern coarser and blackish and darker hindwing. Male genitalia differ by extremely broad valva, arrow-like juxta, straight, elongate aedeagus with tubular vesica bearing basal diverticulum and large, finely spined patch centrally.

Description. Adult (Figs 8, 9, 24, 25). Wingspan 46–49 mm. Palps large, upcurved over head, their 3rd segment moderate, about half length of 2nd, in female 3rd segment larger than in male; palps covered with elongate grey-brown scales, 3rd segment covered with fine scales, with yellowish apical brush in male. Tegulae and patagia covered with brown-grey scales, mixed with yellowish, bordered by pale grey. Female colouration not differing from that of male, but wing pattern more distinct. Forewing dark grey-brown with blackish-brown wing pattern. Subbasal line pale, bordered with wide blackish-brown subbasal field; medial field greyish-brown with blackish indistinct orbicular and dark suffusion along anal vein; antemedial line pale, double, with medial extension, bordered outwardly with dark blackish suffusion in costal part; subterminal line indistinct or represented by indistinct dentate line; subterminal field dark-brownish with blackish-brown dashes; subterminal line as broken triangular streaks; terminal field blackish-brown, cilia brown. Hindwing dark, in basal part yellowish-grey with blackish-brown suffusion; subterminal line waved, terminal field wide, blackish-brown. Male genitalia. ( Fig. 41 ). Uncus very large, curved basally and subapically, terminated by sclerotised hook; subscaphium strong, not extended apically; tegumen broad, about one third longer than sacculus; juxta arrow-like; transtilla as sclerotised band; valva extremely broad, with parallel margins, rounded apically. Aedeagus large, straight; vesica tubular, tapered apically, with basal diverticulum and central finely scobinated patch. Female genitalia. ( Fig. 49 ) Papillae anales moderate, quadrangular; apophyses anteriores somewhat shorter than posteriores ones; antrum small, funnel-like, slightly sclerotised; ductus bursae moderate in length, slightly sclerotised in basal part; corpus bursae sack-like, with small slightly sclerotised bulla near joining with ductus bursae.
