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
). 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

stalked with R

and R

and CuA

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
): 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
): 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.
