Type material.

Holotype ♂ - China,Guangxi Zhuang Autonomous Region: Yinsha Protection Station (24°8'N, 110°11'E), Jinxiu County, 700 m, 27.IV.2008, leg. Hui Zhen and Li Zhang, genitalia slide No. SYL11094. Paratypes: 2 ♀, same data as for holotype.

Diagnosis.

This species is similarto Endotricha hoenei Whalley, 1963. It can be distinguished by the black or deep blackish brown body; the male genitalia with the sacculus squared basally; and the female genitalia with antrum as thick as ductus bursae and having the signum located at posterior 1/3 of corpus bursae. In Endotricha hoenei , the body is purplish red; the sacculus is triangular basally; and the antrum is narrower than the ductus bursae.

Description.

Adult (Fig. 3): Wing expanse 21.0 mm. Head yellow. Antenna yellowish brown, with blackish brown dorsal annuli. Labial palpus with basal and second segments blackish brown except second segment pale yellow at apex, third segment pale yellow. Thorax and tegula blackish brown. Forewing blackish brown in male, black in female; costal margin with creamy white dots interrupted by short black streaks along distal 2/3, with an ill-defined ocherous yellow patch at inner side of subterminal line; antemedian line yellow, widened to an inverted triangular spot on anterior 1/3, narrowed to beyond dorsal 1/3; discal spot black, small, placed on outer margin of antemedian line; subterminal line purplish reddish brown, sinuate, extending inward to tornus; terminal line black; fringe orange yellow except black at apex and from 1/2 to 3/4 of termen, with a distinct black line at base from anterior 1/4 to before tornus, reddish brown on dorsal margin. Hindwing black; median line yellow, broad, slightly widened medially, narrowed posteriorly; terminal line black; fringe yellow, with a distinct black basal line, pale yellow along dorsal margin. Legs yellow except fore- and midlegs blackish brown on ventral surface.

Male genitalia (Fig. 11). Uncus wide at base, narrowed to about middle, then widened to blunt apex; uncus arm triangular, blunt apically; uncus processes ciliiform, placed at about middle. Gnathos short, racket-shaped,rounded at apex. Valva elongately narrow, narrowed basally, rounded apically. Sacculus with basal half squared, distal half suddenly narrowed to a slender rod-shaped process. Vinculum broad, narrowed anteriorly; saccus short, rounded anteriorly. Juxta broad, slightly narrowed letaromedially, with fine satae posteriorly. Phallus slender, about 2/3 length of valva; ductus ejaculation from basal 1/4.

Female genitalia (Fig. 16). Ovipositor nearly triangular, narrowly rounded caudally. Apophysis posterioris two times length of apophysis anterioris.
