(Figs. 2 A-F)
Type material. Holotype: male, LAOS: Bolikhamsai Prov., Phou Khao Khouay National Protected Area, 18°27’23’’N 103° 03’05’’E, 470 m, 2 viii 2019, leg. YS Bae, MJ Qi, DJ Lee, TG Lee, YB Cha, JH Ko, & CM Jang; gen. side no. CIS-8103.
Diagnosis. This new species is one of the smallest species of the genus Torodora Meyrick, and similar to the following new species, T. canalis sp. nov., but it can be distinguished from the latter and its allies by the following diagnostic characters: i) the antenna with distinct dark-brown annulations on flagellum; ii) the forewing with a large, blackish fascia before middle and an elongated trapezoidal patch arising from 2/3 of costa extended to the lower margin of discal cell; iii) the forewing termen deeply concave beyond the apex; and iv) the valva of male genitalia having a short process medially followed by deep emargination on the ventral margin.
Description. Male (Fig. 2 A-C). Wingspan 11.0 mm. Head: Covered with shiny, orange-gray or brownish-gray scales dorsally. Basal segment of antenna elongated, dark brown on dorsal and ventral surfaces, creamy-white on anterior and posterior surfaces; flagellum creamy white, with distinct, dark-brown annulations (Fig. 2C). Second segment of labial palpus thickened, brownish gray on outer surface, with white ring at apex; 3rd segment strongly upturned, as long as 2nd segment, blackish ventrally. Thorax: Tegula and thorax brownish gray dorsally. Forewing ground color brownish gray, scattered with dark-brown scales; a large, irregular-shaped, blackish fascia well-developed before middle, triangularly emarginated medially on outer margin and an elongated trapezoidal patch arising from 2/3 of costa extended to the lower margin of discal cell, surrounded by white line; postmedian white line more or less zigzagged, arising from 4/5 of costa; apex sharply produced; termen strongly concave beyond apex, with black scales along margin; fringe brownish orange. Hind wing pale brownish gray, Abdomen (Fig. 2F): Spinous zones broadly developed; sternite VIII broad, with slightly sinuate posterior margin.
Male genitalia (Figs. 2D, E): Uncus rather short, with rounded apex. Median process of gnathos rather small, strongly bent beyond basal 2/3. Tegumen weakly sclerotized, deeply concave on anterior margin. Valva broad at base, basal part nearly quadrate; costa sclerotized, nearly straight in basal 1/5, then abruptly oblique, nearly with right angle, deeply concave before middle; ventral margin with short process beyond middle followed by deep emargination; cucullus thumb-like, with rounded apex, densely setose; sacculus narrow, extended to lower corner of cucullus. Juxta rectangular, concave on caudal margin, with a small, triangular median plate; lateral margin slightly concave medially. Vinculum narrow, banded; saccal zone rounded. Aedeagus stout, broader than basal part of valva, shorter than valva, slightly narrowed distally, bifurcated apically: dorsal process broadened distally with truncate caudal margin; ventral process bar-shaped, with two small triangular spines medially; cornuti consisting of a long heavily sclerotized stripe extended from near basal 1/4 to near apex, with a bird-shaped heavily sclerotized distal plate, and with a long, large sac from near base to near 2/3, bearing numerous conic spines internally.
Female unknown.
Distribution. Laos (Bolikhamsai).
Etymology. The species name is derived from the Latin, barathrum (= gulf, pit), referring to the hollowed emargination on the ventral margin of valva in the male genitalia.
