Torodora rectivalvata Park , sp. nov.

( Figs. 7 , 14, 14 a, 17)

Type. HOLOTYPE ɗ, Chiang Mai, Doi Inthanon, ca. 1300 m, Thailand, 30.V.1983 (Kurok Moriuti, Arita, & Yoshiyasu), gen. prep. no. CIS-4960. PARATYPE. 1&, same locality, 1, 3.XI.1985 (Moriuti, Saito, & Arita), gen. prep. no. CIS-5244.

Diagnosis. Torodora rectivalvata is superficially similar to T. spinula but the ground color of the forewing is paler than any other species. The male genitalia provide the most diagnostic differences: valva with the costa nearly straight in the basal half, and the distal part nearly triangular; and the juxta with a heavily sclerotized, large triangular median flap.

Description. Male and female. Forewing length 17.5–18.0 mm. Head grayish orange. Tegula and thorax brownish orange. Antenna with pedicel pale brownish orange, shiny dorsally; flagellum pale brownish orange throughout, without clear annulations. Second segment of labial palpus brownish orange on outer surface, paler on inner surface; 3rd segment as long as second, dark brown ventrally. Forewing elongate, broader towards apex; ground color shiny brownish orange, often with large pale orange, quadrate area mesially on upper surface; apex obtuse; termen oblique, slightly concave mesially; fringe golden brown at basal half, paler beyond. R3 stalked at basal 1/3; R4 and R5 stalked beyond basal 2/3; R5 to termen; M1 close at base; M2 and M3 connate at base; M3 and CuA1 stalked near basal 1/3. Hindwing pale yellowish brown; apex acute; M3 and CuA1 stalked beyond 2/3; fringe golden brown. Hind tibia with brownish hairlike setae in distal half dorsally.

Male genitalia ( Figs. 14, 14 a). Eighth sternum broadly convex, spinous zone dense and narrow. Uncus funnel-shaped; caudal margin nearly straight. Ganthos broad basally, strongly curved beyond middle. Costa of valva nearly straight, without subbasal expansion; distal part almost triangular, narrowed toward apex. Juxta with short, digitate or triangular lateral lobes, widely separated; median flap well developed, free, large, triangular, heavily sclerotized. Aedeagus short; with a pair of bar-shaped cornuti of comparable length, one thin, one much stouter.

Female genitalia ( Fig. 17 ). Eighth sternum slightly emarginate at middle. Apophysis anterioris very short. Ostium bursae broad; anterior margin concave. Antrum heavily sclerotized, long, broad, about as long as ductus bursae. Ductus bursae membranous, narrow. Corpus bursae ovate, large; signum strawberry-shaped, with numerous conical spines on surface, about 1/4 as long as corpus bursa.

Distribution. Thailand (Chiang Mai)

Etymology. The species name is derived from the Latin, rectus (= straight), referring to the straight costa of the valva.
