( Figs 11 , 28 ) Type material. CHINA , Guangdong : Holotype ♁, Mt. Dadong , Lianzhou County , 650 m , 25.VI.2004 , leg. DD Zhang , slide No. ZD 21315. Diagnosis. The new species can be distinguished from its congeners by the yellow subbasal fascia of the forewing with posterior 1/3 twice as wide as the anterior 2/3, and the costal margin having two small yellowish-white spots; in the male genitalia by the tegumen with a triangular process on the right margin. Description. Adult ( Fig. 11 ). Wingspan 16.0 mm. Head with frons and vertex yellow, mixed with brown scales. Antenna: scape dark brown mixed with yellow dorsally, pale yellow ventrally; flagellum dark brown alternated with light yellow dorsally and yellowish brown ventrally. Labial palpus: second palpomere yellow; third palpomere dark brown except basal 3/4 yellow dorsally, with a pale yellow streak running from base to apex on ventral surface. Thorax and tegula tawny, with yellow scales on outer margin. Forewing tawny; subbasal fascia yellow, inner margin nearly straight, outer margin from 1/5 of costal margin oblique to fold, then straight to dorsum, posterior 1/3 twice as wide as anterior 2/3, edged with dark brown scales; costal margin with small yellowish-white spot at 1/2 and 1/5 respectively; fringe yellowish brown. Hindwing and fringe yellowish brown. Fore- and midlegs yellowish brown on ventral surface, yellowish white on dorsal surface, tarsus with dark brown scales; hindleg yellowish white, tibia and tarsus with dark brown scales on outer surface. Male genitalia ( Fig. 28 ). Socius symmetrical, slender, gradually narrowed to pointed apex. Tegumen with a shallow anterior emargination, with a triangular process near right anterolateral corner. Vinculum narrowly banded. Valva asymmetrical: left valva with ventral margin produced semicircularly between 1/6 and 1/3, with short setae, basal 1/3 to 3/4 slender, distal 1/4 expanded ovally, with short spines at apex; valvella slender, rounded at apex, as long as 3/4 length of left valva. Right valva much stronger, broadened towards apex, apex with sparse setae, concave at middle, dorsoapical corner produced and narrowed to rounded apex, ventral corner obtusely rounded; valvella with basal half wide, sharply narrowed from beyond middle to pointed apex, with sparse setae. Anellus with a long clubbed posterior process, longer than socius, rounded at apex. Aedeagus stout; cornuti consisting of a bunch of fine spines running from middle to distal 1/4 and a cluster of strong spines at apex. Female unknown. Distribution. China ( Guangdong ). Etymology. The specific epithet of the new species is derived from the Latin bipunciatus , referring to the two yellowish-white spots on the costal margin of the forewing.
