Diagnosis. Adult (Figs 14, 15, 32–35). The species differs from its congeners by stronger bipectinate antennae of male, short palps of male with tiny 3 rd segment, yellowish-brown colouration of forewing, more distinct wing pattern and details of male and female genitalia. Wingspan male 46–52 mm, female 55–59 mm. Palps of male relatively short, with 3 rd segment about ¼ length of 2 nd, covered with dense brown mixed with whitish scales, longer in frontal side; palps of female with 3 rd segment longer than in male, about 1 / 3 length of 2 nd. Antennae of male shortly bipectinate, ciliated, female antennae thinner than in male, strongly fasciculate, ciliated. Head and thorax covered with brown mixed with pale brown hair-like scales; tegulae and patagia bordered with pale-whitish. Ground colour of forewing yellowish-brown with suffusion of whitish or pale greyish scales; wing pattern typical for the genus, formed by pale whitish- brown dentate basal, subbasal and antemedial lines; subbasal and antemedial fields darker than background; medial field with wide diffused medial shadow; reniform as short vertical streak; subterminal line dentate, broken. Hindwing pale yellowish-brown or yellowish basally, with relatively narrow waved brown subterminal band and wide brown terminal field. Male genitalia. ( Fig. 45View FIGURES 42 – 45) Uncus moderate, about half length of tegumen, curved and hooked apically; compared with other Ortopla  species it is not curved and not extended basally; scaphium rather narrow, extended apically, but its apex is not bifurcated as in other species; valva somewhat longer than on other Ortopla  , with parallel margins; aedeagus short and rather broad with vesica bearing basal and medial diverticula and medial patch of minute scobination. Female genitalia. ( Figs 52, 53View FIGURES 46 – 53) Differs from other Ortopla  species by wider ductus bursae, stronger bulla in joining of ductus and bursa and by pyriform shape of bursae.
