( Figs. 5A–F ) Type material. Holotype : ♀ , Cambodia , Mondulkiri , Seima , 12°14’11“N 107°02’37“E , 12 i 2013 , leg. YS Bae , YD Ju, BS Park, & HJ Lee ; gen. slide no. CIS-8081. Diagnosis. This species is also superficially similar to T. parthenopis (Meyrick, 1932) and T. alterniella sp. nov. in the forewing color pattern and marking, with a black spot near apex, but it can be easily distinguished from the latter by a unique character in the antenna with a distinct blackish bar with the length of 3–4 segments in basal 1/3 of flagellum. The female genitalia can be distinguished from those of T. parthenopis by the signum with width about 2 times longer than length, whereas the signum of T. parthenopis is heart-shaped, with stronger conic spines in posterior 1/3 with more or less rounded anterior margin. FIGURE 5. Torodora cupriella Park , sp. nov . : A, adult, holotype; B, close-up antenna, with arrow indicated the blackish part; C, labial palpus in lateral view; D, female genitalia, gen. slide no. CIS-8081, holotype; E, close-up abdominal sternite VIII-posterior part of ductus bursae; F, close-up signum. Scale bar for genitalia: 1.0 mm. Description. Adult ( Figs. 5A–C ). Wingspan12.0 mm. Head : brownish orange dorsally, with erect yellowish white scales laterally. Antenna about 1.3 times longer than the length of forewing; scape elongated, dark brown on dorsal and ventral surface; and creamy white on anterior and posterior surface; flagellum with distinct creamy-white and black rings alternatively, having a distinct blackish bar with the length of 3–4 segments in basal 1/3 as indicated with an arrow in the Fig. 7B. Second segment of labial palpus thickened, slightly arched, yellowish brown on dorsal surface; apex with creamy-white scales; 3 rd segment slender, as long as 2 nd segment, dark brown speckling with yellowish-white scales on outer surface. Thorax : Tegula and thorax grayish orange dorsally. Hind tibia pale grayish orange, lacking rough scales above; 1 st –3 rd tarsi dark brown in basal 3/4, then creamy white in distal 1/3. Forewing ground color grayish orange, more or less yellowish brown in basal half, with an obscure, short, white line arising from near middle of costa and clear, oblique creamy-white line arising from 3/4 of costa, running toward 1/3 of termen; a small black spot near apex, boarded with white scales below; no distinct black dots presented along termen; apex more or less acute; termen very oblique, slightly concave before middle; fringe concolorous with ground color. Abdomen ( Fig. 5F ): Spinous zones on tergite narrowly arranged into two rows along posterior margin. Female genitalia ( Fig. 6D–F ): Apophyses anteriores separated into two arms in basal half. Antrum membraneous, funnel-shaped; lateral margins boarded by sclerotized, rounded line. Ductus bursae very narrow in distal 1/8, then inflated in 1/3 length, narrowed in anterior half; ductus seminalis arising from between narrowed distal part and inflated part of ductus bursae. Corpus bursae more or less elongated, semi-ovate; signum plate large, width about 2x longer than length, bearing numerous conic spines. Male unknown. Distribution. Cambodia ( Mondulkiri ). Etymology. The species name is derived from the Latin, cupri (= copper), with a Latin diminutive suffix, -ella, referring to the forewing ground color.
