( 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. FIGURE 2. Torodora spathiana Park , sp. nov . : A, adult, holotype; B, labial palpus, in lateral view; C, hind tibia; D, male genitalia, gen. slide no. CIS-6063; E, aedeagus; F, abdominal segments VIII; G, genitalia of T. paratidosa (Wu) , gen. slide no. CIS-6689 from Cambodia. Scale bar for genitalia and aedeagus: 1.0 mm. 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.
