Diagnosis.

The male genitalia of the new species is similar to that of the type species, O. callirrhabda (Meyrick, 1936). It can be distinguished by the forewing having two black patches, CuA1 stalked with CuA2, and ductus seminalis having dense granules; in O. callirrhabda , the forewing has no black patches, CuA1 and CuA2 are separate, and the ductus seminalis has no granules.

Description.

Wingspan 13.0-15.0 mm (Fig. 4 ). Head dark brown. Antenna yellowish brown in basal 1/4, pale yellow in distal 3/4. Labial palpus yellowish brown, paler on inner surface; third palpomere as long as second palpomere. Thorax and tegula dark brown. Forewing dark brown, with two large, elliptical, black patches anteriorly reaching anterior margin of discal cell: first at basal 1/4, posteriorly reaching fold; second at middle, posteriorly reaching above dorsum; fringe dark brown; CuA1 and CuA2 short-stalked. Hindwing and fringe greyish brown; fringe with an orange white basal line.

Male genitalia (Fig. 12 ). Uncus subcrescent. Gnathos with basal plate bell-shaped, bearing a papillary process at middle on posterior margin; median process wide in basal 1/3, narrowed to distal 2/5, thereafter slender to pointed apex, curved ventrad at distal 1/4 by a right angle. Valva wide in basal 1/4, narrowed slightly to cucullus; cucullus about half length of valva, narrowed slightly to obtusely oblique apex, costal margin shallowly concave except convex at base, ventrobasal process subtriangular, with a rounded apex; costal bar narrow, slightly expanded dorsad medially; sacculus a broad band, about 1/4 length of ventral margin of valva. Saccus rounded on anterior margin. Juxta broadly concave on posterior margin, denticulate along lateral sides of concavity; with a trapezoidal process at middle on anterior margin; posterior lobe strongly horn-shaped, curved outward at middle; posterolateral lobe short, narrow, extending laterally. Aedeagus nearly as long as valva, slightly widened medially, dorsal denticles larger than cornuti; cornuti consisting of 1-3 conic spines.

Female genitalia (Fig. 19 ). Eighth abdominal sternite convex on posterior margin. Apophyses posteriores twice the length of apophyses anteriores. Antrum subrectangular, wrinkled, membranous except sclerotized along posterior margin forming a band. Ductus bursae narrowed posteriorly, widened distinctly toward corpus bursae, with diffused granules near base of ductus seminalis; ductus seminalis broad, with dense granules on inner wall. Corpus bursae large, elliptical; with two signa: one elliptical, with dense denticles, the other plate-shaped, bearing 3-6 teeth (Fig. 19a, b ).

Distribution.

China (Chongqing, Henan, Hubei, Jiangxi, Shaanxi, Yunnan, Zhejiang).

Etymology.

The specific epithet is derived from the Latin condensatus, referring to the dense granules in the ductus seminalis.
