( Figs 8 , 41 , 71 ) Type material. Malaysia : Holotype ♂ , Cameron Highlands , Gunung Brinchang , 1980 m , 15–23.VIII.1986 , leg. G.S. Robinson , slide No. NHMUK010317151 . Paratype . 1♀ , same data as holotype, slide No. NHMUK010317117 . Diagnosis. The new species can be recognized by the forewing having a second white line curved twice from basal 2/5 of the dorsum to near base of the anterior margin of the cell; and in the male genitalia by the sacculus having a tiny spine at distal 1/4 on the ventral margin, and the phallus with a large hooked cornutus. Description. Adult ( Fig. 8 ). Forewing length 6.0 mm. Head . Vertex dark grey, mottled with ochreous brown and white laterally; frons white; occiput ochreous brown, mixed with white scales. Labial palpus with second segment black mixed with white, with a white ring near apex; third segment black, white at base, middle and apex respectively. Antennal scape black dorsally except white at apex, pale grey ventrally; flagellum black, with white annuli dorsally. Thorax. Mesonotum and tegula ochreous brown. Forewing ochreous yellow; costal spot situated at distal 1/3, white, small, beyond with diffused grey scales forming a large grey spot extending across posterior angle of cell; dorsum with three white lines margined with black scales: first line from near base of dorsum oblique inward to base of fold; second line from basal 2/5 of dorsum extending inward to below basal 1/4 of fold, then extending horizontally and outward to distal 1/3 of fold, again curved inward to near base of anterior margin of cell; third line running from distal 1/5 of dorsum obliquely outward to distal 1/6 of posterior margin of cell; tornal spot grey, with black scales, extending to costal spot; apical spot white, ovate, with dense greyish brown scales on inner margin; fringe yellow except grey around tornus. Hindwing and fringe grey. Foreleg black except femur dark brown dorsally, white ventrally, tibia with white spot at base and middle, with a tuft of white scales at apex, tarsus white at apices of basal two and apical tarsomeres; midleg pale greyish brown ventrally, black dorsally except femur white, tibia with a white spot at base, with a tuft of white scales at middle and apex respectively, tarsus white at apices of basal two tarsomeres and on entire apical tarsomere; hindleg yellowish brown ventrally, black dorsally, tarsus white at apices of basal three tarsomeres and on entire apical two tarsomeres. Male genitalia ( Fig. 41 ). Uncus bell-shaped, basal 1/2 uniform in width, distal 1/2 slender, clubbed, rounded apically. Gnathos slightly longer than uncus; mesial plate sub-triangular, narrowed to apex, with scaly protuberances distally. Tegumen furcate from middle; lateral arm narrowed to anterior end. Valva broad, sub-rectangular, slightly narrowed from distal 1/4 to rounded apex, setose distally; costa with a narrow band, convex at distal 1/3; sacculus wide at base, slightly narrowed to apex, distally bent dorsad along apex of valva, with a tiny spine at distal 1/4 on ventral margin. Saccus shorter than uncus, triangular, broadened at base, narrowed to pointed apex. Juxta narrowly linked basally; lateral arm heavily sclerotized, wide at base, narrowed to flat apex. Phallus longer than valva, straight; cornutus long, about same length as phallus, hooked. Female genitalia ( Fig. 71 ). Eight tergum and sternum rectangular, with sparse setae on posterior margin. Apophyses anteriores 2/3 length of apophyses posteriores. Antrum cup-shaped. Ductus bursae sclerotized, except partly membranous medially. Corpus bursae shorter than ductus bursae, rounded; signum being two, overlapping, narrow plates with dense denticles. Distribution. Malaysia . Etymology. The specific epithet is compounded from the Latin curvus and lineatus , referring to the shape of the second curved line of the forewing.
