CIS-6787 . Paratypes : 3 ♂ , same data as the holotype; genitalia (gen.). slide no. CIS-6790, -7181 . Diagnosis. The new species is characterized by the elongated forewing with light-orange basal fascia and a large, half-moon-shaped, light orange costal patch medially. Description. Adult ( Figs. 1A, B ). Wingspan 20.5–21.0 mm. Head : Light yellow dorsally. Antenna much longer than forewing, about 1.3 times length of forewing; scape elongated, slightly dilated apically, light yellow all around; flagellum light yellow, without annulations, not ciliate. Second segment of labial palpus slender, slightly thickened, about 3 times the length of diameter of compound eye; light yellow all around; 3 rd segment slightly longer than 2 nd segment, strongly upturned, sharply pointed apically, light yellow all around. Thorax : Tegula and thorax light yellow. Hind tibia light yellow, with dark-brown scale-tuft at middle and at end dorsally; tarsi light yellow. Forewing ground color yellowish brown, with light-orange, more or less triangular basal fascia; costal patch large, half-moon-shaped, light orange, occupied from 2/5 to 2/3 on costa, followed by narrow light orange band along costa beyond apex; apex obtuse; termen oblique, nearly straight; fringe light orange before tornus, yellowish brown around tornus; venation with R 1 arising from before middle; distance between R 2 and R 3 about half the length of R 1 and R 2 ; R 3 stalked with R 4+5 for about 1/3 length; R 4 and R 5 stalked for more than 2/3 length; R 5 to apex; M 2 and M 3 nearly connate at base; CuA 1 and CuA 2 stalked for basal 3/5; costa nearly straight from near base, then oblique after end of R 1 ; cell opened; apex obtuse; termen oblique, slightly sinuate. Hind wing ground color yellowish brown, with a broad, orange-white area along below costa; apex acute; termen extremely oblique, slightly sinuate; fringe concolorous with ground color, with narrow, yellowish-white basal line; venation with Rs and M 1 short stalked; M 2 close to CuA 1 at base; M 3 and CuA 1 stalked for about 1/3 length. Abdomen (Fig. F): Spinous zones broadly developed with fine spines; segment VIII not modified. Male genitalia ( Figs. 1C–E ): Uncus heavily sclerotized, stout, pointed apically. Median process of gnathos large basally, narrowed toward apex; bent downward pre-apically. Tegumen weakly sclerotized, concave on anterior margin. Valva broad at base; costa slightly expanded anteriorly in basal 1/4, slightly concave medially; cucullus slightly longer than basal part of valva, narrowed toward apex, dense setose; apex rounded; sacculus narrowly elongate to lower corner of cucullus. Vinculum banded, sclerotized. Juxta shield-shaped, weakly sclerotized, without caudal processes, emarginated at middle on anterior margin. Aedeagus stout, as long as valva; cornutus crescent plate with spine-like process. Female unknown. Distribution . Cambodia ( Pursat Prov. ). Etymology. The species name is derived from the Latin, helvus ( = yellow) and nota (= mark), with a Latin diminutive suffix, referring to the yellowish mark on the forewing.
