Type material.
Holotype: China: ♂, Baoshan, Baihualing, Hanlongzhai (25°18'N, 98°49'E), 1577 m, 2.viii.2015, KL Liu & JX Zhao leg., slide No. YS19429. Paratypes: China: 1♂11♀, same data as holotype, slide No. YS19430♀; 9♂1♀, Yunnan, Gongshan County, Naqiutong Village, 1767 m, 16-18.vi.2017, KJ Teng et al. leg., slide No. YS19426♂.
Diagnosis.
The new species is unique among other species in the genus by having a triangular process at the base of the posterior lobe of the juxta at the inner margin. It is similar to O. hybocentra sp. nov., and the differences between them are stated in the diagnosis of the latter species.
Description.
Wingspan 13.0-13.5 mm (Fig. 8 View Figures 3–10 ). Head dark brown. Antenna with scape brownish yellow; flagellum orange yellow. Labial palpus orange yellow except dark brown ventrally on third palpomere; third palpomere as long as second palpomere. Thorax and tegula dark brown. Forewing dark brown, with two, narrow black patches, one at the basal 1/4 and one in the middle, distal 1/3 with diffused black scales; fringe dark brown; CuA1 and CuA2 short-stalked. Hindwing and fringe brown.
Male genitalia (Fig. 15 View Figures 15–17 ). Uncus subcrescent, broad V-shaped on posterior margin. Gnathos with median process slightly broad in basal 1/3, thereafter slendered to pointed apex, curved ventrad at distal 1/3 by a right angle. Valva wide in basal 1/4, narrowed distinctly to cucullus; cucullus about half length of valva, almost tubular, apex obtuse, costal margin shallowly concave, ventrobasal process thumbed; costal bar narrow, expanded dorsad medially; sacculus wide in basal half, slender in distal half, reaching cucullus. Saccus obtuse on anterior margin. Juxta subquadrate, broadly concave on posterior margin, densely denticulate along lateral sides of concavity; anterior margin obtusely produced at middle; posterior lobe large horn-shaped, longer than juxta, curved inward, triangularly produced at base on inner margin; posterolateral lobe small, spiniform. Aedeagus shorter than valva, slightly widened medially, with two tiny dorsal denticles; cornuti consisting of more than ten large, needle-like spines running from basal 1/4 to 3/4.
Female genitalia (Fig. 22 View Figures 18–22 ). Eighth abdominal sternite obtuse on posterior margin, with a sclerotized sac at anterolateral corner. Apophyses posteriores about twice length of apophyses anteriores. Antrum membranous except sclerotized along posterior margin forming a band, with two symmetrically sclerotized, leaf-like sclerites medially. Ductus bursae wrinkled, narrowed posteriorly, widened toward corpus bursae, with numerous conic spinules in anterior 3/5; ductus seminalis broad, arising from ductus bursae anteriorly, with sparse thorns on inner wall. Corpus bursae elliptical; signa consisting of several teeth of varied size in a longitudinal row placed posteriorly and a densely denticulate plate placed at middle.
Distribution.
China (Yunnan).
Etymology.
The specific epithet is derived from the Latin introflexus, referring to the medially curving posterior lobes of the juxta.
