( Figs 11 View FIGURES 6‒11 , 28 View FIGURES 24‒29 )
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 View FIGURES 6‒11 ). 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 View FIGURES 24‒29 ). 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.
