Ourapteryx longiacutata Jiang & Cheng , sp. nov. ( Figs 6 View Figures 1–15 , 26 View Figures 20–27 , 43 View Figures 36–44 )
Description. Head. Antennae filiform in both sexes, grey suffused with sparse white scales, white near base dorsally. Frons dark yellowish brown. Labial palpus dark yellowish brown mixed with sparse blackish brown scales. Vertex white, suffused with sparse pale yellow scales.
Thorax. Patagia, tegulae and thorax white. Legs yellowish white with sparse black spots, black patches present between femora and tibia of fore- and median legs, hind tibia not dilated in male, without hair-pencil, both sexes with two pairs of spurs. Forewing length: male 23–27 mm; female 26–29 mm. Forewing with apex acute, outer margin almost straight. Hind wing with a long tail, acute at tip, shoulder prominent. Wings white. Forewing with short black streaks on costal area between base and postmedial line; antemedial and postmedial lines straight and yellowish brown, former nearer to latter on anal margin than on costa; discal spot linear and yellowish brown; submarginal area diffused with pale grey striation; terminal line black, invisible near apex and anal angle; fringes mostly yellowish brown, white near apex and anal angle. Hind wing with discal spot indistinct; medial line mostly straight, curved posteriorly, greyish brown; submarginal area densely diffused with pale greyish brown striation; terminal line black, invisible near shoulder and tip of tail and anal angle; fringes mostly reddish brown, white near shoulder and tip of tail and anal angle; tail with two spots at base, connected by a dark grey band, anterior large, dark red, edged with black, posterior represented by a black spot. Underside white, transverse lines faintly indicated. Forewing with R 1 and R 2 coincident.
Abdomen. Abdomen white without setal comb on third sternite.
Male genitalia. Uncus stout with acute apex. Socii relatively large, and membranous. Gnathos with median process small and rounded. Valva long and broad, simple, rounded and narrow apically; costa weakly swollen medially. Furca developed on right side, long and narrow, reaching beyond base of uncus, slightly curved at apex, terminating with a dense row of thorns. Saccus rounded and short. Aedeagus cylindrical; vesica with a sclerotized plate densely covered with numerous short cornuti, all of similar size.
Female genitalia. Lamella postvaginalis and lamella antevaginalis almost semicircle and equal in length, former folded at posterior margin and with an oblique ridge from left side towards ostium. Colliculum present. Ductus bursae with longitudinal ribs and sclerotized, curved posteriorly. Corpus bursae globular, shorter than ductus bursae; signum centrally; signum large and rounded with marginal spines, disc small and rounded.
Diagnosis. The species can only be distinguished from O. karsholti Inoue, 1993 ( Figs 7 View Figures 1–15 , 44 View Figures 36–44 ) by the longer tail of the hind wing and the shorter lamella antevaginalis (shorter than the length of the lamella postvaginalis), while in O. karsholti , the lamella antevaginalis and the lamella postvaginalis are of equal length.
Etymology. The specific name refers to the long furca with acute apex.
