Diagnosis. Torodora digitalis sp. nov. is the smallest species of the known species of the genus Torodora Meyrick , with the wingspan 10.0 mm. The species can be distinguished from its allies by the male genitalia: i) the basal part of the costa forming a costal bar-like band, which is more or less similar to the main diagnostic character of the genus Lecithocera ; ii) juxta with digitate latero-caudal lobes; iii) aedeagus strongly arched, with uniquely developed bar-like sclerite apically.

Description. Male ( Figs. 4A, B View FIGURE 4 ). Wingspan 10.0 mm. Head: Dark yellowish brown dorsally, with yellowishwhite scales laterally. Antenna slightly longer than forewing; basal segment elongated, dark brown on dorsal surface, yellowish white on anterior and posterior surface; flagellum orange white, without distinct annulations. Second segment of labial palpus thickened, dark brown dorsally with yellowish-white apex dorsally, yellowish white in apical 2/5 ventrally on outer surface; yellowish white on inner surface; 3 rd segment, slender, as long as 2 nd segment, dark brown ventrally. Thorax: Tegula and thorax dark brown dorsally. Hind tibia covered with dark-brown scales in basal 2/5, yellowish white beyond on dorsal surface. Forewing ground color dark brown evenly (the paratype yellowish brown, partly descaled), with a minute yellowish-white costal patch beyond 3/4 of costa; venation with R 2 arising from near upper corner of cell; R 3 stalked with R 4+5 for basal 1/3; R 4 and R 5 stalked beyond 2/3; R 5 to apex; CuA 1 and CuA 2 stalked for basal 1/3; apex slightly produced; termen oblique; fringe concolorous with ground color. Hind wing pale gray, as wide as forewing; venation with M 3 and CuA 1 stalked for basal 2/3; CuA 2 closed to CuA 1 at base. Abdomen ( Fig. 4G View FIGURE 4 ): Abdomen dark brown dorsally, yellowish white ventrally, with broadly developed spinous zones dorsally; segment VIII with a narrow, linear sclerite dorsally.

Male genitalia ( Figs. 4C, E View FIGURE 4 ): Uncus elongated, narrower toward apex, exceeding basal plate of gnathos, bent apically downward. Median process of gnathos strong, narrower toward apex, strongly bent with nearly a right angle beyond 2/3 downward. Tegumen weakly sclerotized, deeply concave in inverted V-shape on anterior margin. Valva broad at base, basal part of costa forming a costal bar-like band; costa deeply concave; cucullus narrowed apically, strongly upturned, with strong, dense setae on surface; Juxta broad, pot-shaped, with digitate latero-caudal lobes. Vinculum banded, bent apically inward. Aedeagus strongly bent, shorter than valva, broad basally, narrowed beyond half, with uniquely developed bar-like sclerite apically.

Female unknown.

Distribution. Laos (Bolikhamsai).

Etymology. The species name is derived from the Latin, digitalis (= finger), referring to the digitate latero-caudal process of the juxta in the male genitalia.
