( Figs. 14View FIGURES 9 – 16, 25, 26View FIGURES 23 – 28, 35View FIGURES 29 – 36)

Types. Holotype: male, Primorye terr., Spassk district, Jakovlevka, 29.vi. 1926, leg. A.M. Djakonov & I.N. Filipjev [ ZISP]. Paratypes: 1 male, Primorye terr., De-Friz peninsula, 26.vii. 1963, leg. M. Omel’ko; 1 female, south Primorye terr., Peishula, 15.vii. 1963, leg. M.I. Fal’kovich; 1 male Primorye terr., vicinity of Vladivostok, Okeanskaya, biological station, 20.vii. 1963, leg. M.I. Falkovich [ ZISP]; 2 males 1 females, Primorye terr., Spassky distr. Dmitrievka, 15.vii – 4.viii. 1984 ex larva on soya (Kulikova)  ( IBSS); 1 males Japan, ex coll. K.S. Popov, female [ ZISP].

Diagnosis. P. curvicornuta  is similar to P. flavomacula  and P. ochreipennis  , but differs from both species in somewhat smaller size and in presence of waved indistinct subbasal line in forewing. In wing pattern it differs from P. flavomacula  by paler reddish-yellow ground colour (pale lilaceous grey in P. flavomacula  ), by shape of antemedial line, which is with invagination in mid part (like in P. ochreipennis  ), and edged outsides by diffused whitish line similar to P. flavomacula  , by postmedial line, which is excurved from costa to vein 6 like in P. ochreipennis  , (obliquely straight in P. flavomacula  ), angled there and thence evenly incurved, edged outsides with thin whitish line similar to P. flavomacula  and by shape of reniform. In the male genitalia P. curvicornuta  most close to P. flavomacula  , but differs in somewhat more massive uncus, much longer (about 3 times) and thinner apical extension of costa and by shape and structure of vesica, having short diverticula armed with strong, hook like curved cornutus and very long diverticula armed with strong straight cornutus. In female genitalia, ductus bursae, S-shaped curved, sclerotized, much narrower than in P. flavomacula  , antevaginal plate with two finger-like lateral extensions.

Description. Adult ( Fig. 14View FIGURES 9 – 16). Palps, head and tegulae yellow, similar to flavomacula  ; pattern of forewing almost identical, with ground colour pale pinkish-yellow, irrorated with ochreous brown; antemedial line brown, diffuse, darker and wider in costal area, angulated just below costa, then nearly oblique, indented at median trunk, edged outsides by whitish suffusion like in flavomacula  ; reniform yellow, more rounded and prominent, than in P. flavomacula  ; median area usually suffused with ochreous brown, medial shadow, which defined posteriorly by brown, postmedial line, which is excurved from costa to vein 6 (obliquely straight in P. flavomacula  ), angled there and thence evenly incurved, edged outsides with whitish; subterminal line dark, dentate, sometimes indistinct; edged outside with pale suffusion; terminal area tinged with pinky-yellowishgrey from apex to near vein 2; cilia pale greyish yellow with pale basal line. Hindwing pale pinky-yellowish grey, more or less infuscate, medial line obsolete, with no discal mark; cilia pale pinky-yellowish grey.

Male genitalia ( Fig. 26View FIGURES 23 – 28). Uncus somewhat more massive than in P. flavomacula  , basally thin, extended apically, splitted on tip; tegumen broad, vinculum narrow; juxta shield-like. Shape of valva similar to those of P. flavomacula  : saccus small; saccular extension very large, massive, directed along ventral margin of valva; costa somewhat more massive than in P. flavomacula  , with thin, curved apically free extension, which is 3 times longer than those in P. flavomacula  . Aedeagus with two diverticula, short one bearing large curved cornutus, long one armed by strong straight cornutus.

Female genitalia ( Fig. 35View FIGURES 29 – 36). Papillae anales quadrangular, narrower than in P. flavomacula  and P. ochreipennis  ; apophyses posterior long, anterior ones 3 times shorter; antevaginal plate expressed, with two lateral finger-like extensions; ductus bursae well shaped, narrower than in P. flavomaculata  , sclerotized, with sclerotized lateral extension, fold and less sclerotized area in caudal part; corpus bursae rounded, bearing minute spine-like signa on inner part of the bursae wall.

Etymology. The specific name “ curvicornuta  ” refers to the characteristic curved cornutus in the vesica.

Distribution and biology. ( Fig. 44View FIGURES 37 – 44). Manchurian, nemoral. Far East (Primorye terr.). China, Korea, Japan. Mesophilous species, occurs sympatrically with preceding species in meadows, woodsides, among bushes, edges of fields; it is rather common on plantations of soybean. The moth flies from mid June to end of July. The larva feed on green and dead leaves of soybean ( Glycine  soy).

Notes. In applied entomological literature the species have been confused with Paragabara flavomacula  and reported for Primorye terr. as the secondary pest of soybean.
