(Figs. 5 A-F)
Type material. Holotype: female, LAOS: Bolikhamsai Prov., Phou Khao Khouay National Protected Area, 18°30’11’’N 102°58’ 06’’E, 68 m, 9 xi 2015, leg. YS Bae, BS Park, SM Na, JW Kim, DJ Lee; gen. side no. CIS- 8077.
Diagnosis. This new species is characterized by the forewing venation: R 3 and R 4+5 unusually with long stalk, R 4 and R 5 short stalked, arising near from R 3 at base. The forewing color pattern is similar to the following new species, Torodora multispinata sp. nov. with a minute, yellowish-white costal patch beyond 3/4 of the costa as in the latter, but it can be distinguished from a narrow basal line on the fringe of the forewing. The hind tibia has more distinct white scales at apex. The female genitalia are differentiated from those of any congeners by having a heart-shaped signum in the female genitalia. It is more or less similar to that of T. sciadosa Wu & Liu, 1994 which was described from China, but the abdominal sternite VIII gently emarginated, whereas in the latter, deeply emarginated; signum more elongated anteriorly, length about 1.5x of width; and the distributional pattern of spines.
Description. Female (Figs. 5 A-C). Wingspan 13.5 mm. Head: Pale yellowish brown dorsally, with yellowish-white scales laterally. Antenna slightly longer than forewing; basal segment dilated distally, yellowish brown on dorsal surface, yellowish white on anterior and posterior surface; flagellum yellowish white, with dark-brown annulations. Second segment of labial palpus thickened, arched, yellowish brown in basal 3/4 and yellowish white in distal 1/4 with narrow yellowish-brown band on outer surface; yellowish white, rarely speckled with brownish scales medially on inner surface; 3 rd segment, slender, longer than 2 nd segment, yellowish white, dark brown ventrally. Thorax: Tegula and thorax yellowish white dorsally. Forewing ground color yellowish brown. Hind tibia with yellowish-white, rough scales above and creamy-white scales at apex. Forewing ground color yellowish brown evenly, with a small, yellowish-white costal patch at 3/4 of costa; apex obtuse; termen concave beyond apex; fringe concolorous with ground color, with narrow yellowish-white basal line and yellowish white apically; venation (Fig 5D) with R 1 arising from before middle; distance between origins of R 2 and R 3 about 1/2 the length of R 1 and R 2; R 3 and R 4 stalked for basal 2/3; R 5 separated from just beyond stalk of R 3 and R 4; R 5 to termen; M 2 much nearer to M 3;, nearly parallel to M 1; CuA 1 and CuA 2 long-stalked, for basal 2/5; cell weakly closed. Hind wing paler than forewing, as wide as forewing; venation with M 2 close to M 3 at base; M 3 and CuA 1 stalked for basal 1/3; cell closed; apex acute; termen sinuate; fringe concolorous with ground color.
Female genitalia (Fig. 5E): Apophyses anteriores about 2/5 the length of apophyses posteriores. Abdominal sternite VIII concave on posterior margin medially, with long setae. Antrum membranous, funnel-shaped. Ductus bursae long, about 1.5x longer than corpus bursae; ductus seminalis narrow, arising from near posterior end of ductus bursae. Corpus bursae ovate; signum large, semiovate, with strong, conic spines in posterior 1/3 and minute ones anteriorly and laterally.
Male unknown.
Distribution. Laos (Bolikhamsai).
Etymology. The species name is derived from the Latin, cordi (= heart), referring to the heart-shaped signum of the female genitalia.
