( Figs 8 View FIGURES 1–8 , 41 View FIGURES 40–45 , 71 View FIGURES 67–72 )
Type material. Malaysia: Holotype ♂, Cameron Highlands, Gunung Brinchang , 1980 m, 15–23.VIII.1986, leg. G.S. Robinson, slide No. NHMUK010317151 About NHMUK .
Paratype. 1♀, same data as holotype, slide No. NHMUK010317117 About NHMUK .
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 View FIGURES 1–8 ). 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 View FIGURES 40–45 ). 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 View FIGURES 67–72 ). 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.
