Diagnosis. In facies, Torodora vietnamensis is nearly indistinguishable from other species of the manoconta species-group, but it is easily distinguished by the heavily sclerotized, horn-shaped lateral lobe of the juxta. The entire structure of the male genitalia is similar to that of T. manoconta Wu & Liu , but it differs from the latter by the more widely expanded uncus caudally, the lateral lobe of the juxta narrowed apically and curved outwardly, and the 8th sternum more convex mesially.

Description. Male. Forewing length 19–20 mm. Head shiny, pale brownish orange, with concolorous erect scales laterally, Tegula and thorax shiny, brown. Antenna with pedicel pale brownish orange, shiny dorsally; flagellum pale brownish orange throughout, with pale brownish annulations. Second segment of labial palpus rather slender, pale brownish orange; 3rd segment as long as second, dark brown ventrally. Forewing ground color shiny, golden brown, often with a yellowish triangular or elongate patch before tornus on inner margin; apex somewhat rounded; termen less oblique; fringe golden brown at basal half, then paler beyond. R3 stalked with R4+5 at basal 1/3; R4 and R5 stalked at basal 2/3 length; R5 to termen; M1 slightly close to R3+4+5 towards base; M2 and M3 connate at base; M3 and CuA1 stalked at basal 1/3, closely parallel. Hindwing pale yellowish brown; apex acute; M3 and CuA1 stalked at basal 1/3; fringe golden brown at basal half and paler beyond. Hind tibia with dark brown hairlike setae preapically.

Male genitalia (Figs. 10, 10a–b). Uncus broadly expanded at apex, almost triangular. Gnathos strongly bent downward. Valva foot-shaped; costa expanded anteriorly subbasally, deeply concave mesially. Lateral lobe of juxta horn-shaped, stout, with heavily sclerotized, acute apex; median flap sclerotized, convex ventrally; caudal margin U-shaped, deeply emarginated. Aedeagus with a pair of slender cornuti: longer one needle-shaped, as long as aedeagus, shorter one stouter, about 1/2 length of longer one. Female unknown.

Distribution. Vietnam (North).

Remarks. The longer cornutus of the aedeagus is sometimes deciduous when the genitalia are dissected, leaving only the round basal plate as shown in Fig. 10a. The round basal plate has a few spine-like fine processes along the margin.

Etymology. The specific name is derived from the country of the type locality.
