(Figs. 2A–F)
Type. Holotype: ♂, Cambodia, Mondulkiri, Seima Biodiversity Conservation area, 3–8 vii 2002, leg. Bae & Chae; gen. slide no. CIS-6063.
Diagnosis. The male genitalia of the new species are similar to those of T. parotidosa (Wu, 1994), which are known in China and Thailand, but it can be distinguished by the valva extremely narrowed beyond the rectangular basal part, and the juxta with asymmetrical latero-caudal lobes. The new species is also differentiated from the latter by the more or less slender 2 nd segment of labial palpus, whereas T. parotidosa has rough scales ventrally.
Description. Adult (Figs. 2A–C). Wingspan 19.0 mm.
Head: Yellowish brown dorsally. Antenna slightly longer than forewing; scape elongated, not dilated apically, grayish orange; flagellum grayish orange, lacking annulations, not ciliate. Second segment of labial palpus thickened; 3 rd segment broken.
Thorax: Tegula and thorax yellowish brown dorsally. Hind tibia with rough scales above from base to near apex; apex with white scales. Forewing ground color grayish orange to yellowish brown, without distinct markings; costa slightly arched around basal 1/3 and beyond 2/3; apex obtuse; termen slightly concave; fringe concolorous with ground color; venation with R 1 arising from beyond middle; distance between origins of R 2 and R 3 less than 1/2 length of R 1 and R 2; R 3 stalked with R 4+5 for basal 1/3 length; R 4 and R 5 stalked for more than basal 2/3; R 5 to termen; M 1 remote from R 3+4; M 2 nearly parallel to M 1; CuA 1 and CuA 2 stalked for basal half; cell closed. Hind wing paler and broader than forewing; venation with M 2; close to M 2; M 3 and CuA 1 nearly connate at base; apex obtuse; termen slightly concave; fringe concolorous with ground color.
Abdomen (Fig. 3F): Spinous zones on dorsal surface nearly triangularly developed.
Male genitalia (Figs. 3D, E). Uncus elongated, heavily sclerotized, bent downward, much exceeded posterior margin of the basal plate of gnathos. Median process of gnathos narrowed toward apex, strongly bent beyond 2/3, sharply pointed apically. Tegumen weakly sclerotized, concave in inverted V-shape on anterior margin. Valva broad at base, quadrate in basal part, abruptly narrowed medially; cucullus broadly expanded into spoon-shaped, with round outer margin; sacculus not developed. Vinculum banded, sclerotized. Juxta shield-shaped; latero-caudal processes asymmetrical, left one longer and right one about 1/2 length of the left, with median ridge in anterior half. Aedeagus very stout basally; width of basal half about 1.5 times than the width of basal part of valva, as long as valva; cornuti consisting of a heavily sclerotized, crescent plate with wrinkled tube basally beyond middle, a long, narrow sac containing numerous conic spines from near base to 2/3 length of aedeagus.
Female unknown.
Distribution. Cambodia (Mondulkiri Prov.).
Etymology. The species name is derived from the Latin, spatha (= spoon-shaped, paddle), with a Latin suffix, - anus, referring /to the paddle-shaped valva in the male genitalia.
