Diagnosis.

The light-orange color pattern of the forewing is unique, with dark-brown streaks between veins. The pattern is more or less similar to that of Timyra aulonitis Meyrick, 1908 which was described from Sri Lanka, but the species can be distinguished by the venation of both wings, and by the absence of the scale projection in the basal segment of antenna and the scale-tuft in the hind tibia which are unique to Timyra Walker, 1864. The male genitalia are also different from those of the Timyra aulonitis .

Description.

Male and female (Figs 1-5, 11): Wingspan, 17-18 mm. Head light orange. Basal segment of antenna (Fig. 5) elongate, light orange, speckled with brownish scales dorsally; flagellum dark brown, sometimes paler from near half to before 7th. Second segment of labial palpus (Fig. 3) gently arched, shiny pale orange; 3rd segment slender, as long as 2nd segment, pale orange speckled with dark-brown scales, with acute apex. Thorax and tegula light orange. Forewing elongate; ground color light orange, clothed with dark-brown scales between veins; costa nearly straight, then gently arched beyond ¾, blackish along anterior margin; apex obtuse; 5-6 large, blackish spots from apex to tornus along termen; termen oblique, not sinuate; fringe light orange in basal 1/3, then dark brown; venation (Fig. 11) with R1 arising from before middle, R2 arising near upper corner of cell, R3 and R4 stalked near 2/3 length of R3+4+5, R4 and R5 stalked about 3/5 length; R5 reach before apex, M1 close to R3 at base, M2 straightly extended from lower margin of discal cell, M3 on common stalk with CuA1+2, CuA1 and CuA2 stalked beyond middle. Hindwing evenly clothed with dark-brown scales, except on veins; light orange along veins; distinct blackish line well-developed from prior to apex to tornus along margin; venation with Rs and M1 nearly connate, M2 absent, M3 and CuA1 stalked. Fore and mid tibia with black scales at apex. Hind tibia (Fig. 11) with rough, dark-brown scales above, denser near apex; tarsi with black scales at apex on each segment. Abdomen clothed with dark-brown scales; abdominal tergites with dense spines; sternite VIII bilobed medially, as indicated in Fig. 12.

Male genitalia (Figs 6-8). Uncus elongate, heavily sclerotized, broadened basally; apex slightly bifurcate. Gnathos relatively short, small, strongly bent downward beyond 2/3. Tegumen long, relatively broad; anterior margin deeply concave. Valva broad; costa slightly concave beyond middle, nearly parallel to ventral margin; cucullus short; outer margin rounded, with dense setae along margin. Juxta shield-shaped, concave in U-shape on caudal margin, with triangular caudal lobes laterally; anterior margin deeply concave. Vinculum narrow, band-shaped. Saccus short, rounded. Aedeagus rather slender, as long as valva, slightly bent; cornutus long, narrow sclerite, as long as 2/3 length of aedeagus. Abdominal tergites with dense spinose zones; sternite VIII bifurcated medially (arrow indicated in Fig. 12).

Female genitalia (Figs 9, 10). Abdominal sternite VIII weakly sclerotized, deeply emarginated on caudal margin medially. Apophyses anteriores less than half length of apophyses posteriores. Antrum (Fig. 10) cup-shaped, weakly sclerotized, about 1/4 length of ductus bursae. Ductus bursae longer than corpus bursae, broadened in distal 2/5 length, then slightly narrowed; ductus seminalis arising from near conjunction with corpus bursae. Corpus bursae large, ovate; signum absent.
