( 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. FIGURE 2. Torodora barathrona Park , sp. nov . : A, holotype; B, paratype in lateral view; C, ditto, head with antenna and labial palpus; D, male genitalia, gen. slide no. CIS-8103, holotype; D, ditto, aedeagus; E; ditto, abdomen. Scale bar for genitalia and aedeagus: 1.0 mm. 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.
