( Figs. 2 View FIGURES 1 – 7 , 9 View FIGURES 8 – 11 )

Type material. Holotype: ɗ, CHINA: Mt. Baxian (Pahsien) [24°09'N, 121°01'E], Taizhong, Taiwan, 800– 900 m, 16.viii.2006, coll. Houhun Li and Xicui Du, genitalia slide no. FXM06124. Paratypes: 3 ɗ, 15– 16.viii.2006, other same data as holotype, 3 ɗ, Mt. Lala, Taoyuan County, Taiwan, 1800 m, 1.viii.2006, coll. Houhun Li and Xicui Du ( NSU).

Diagnosis. This species can be separated from other known species of the genus by the slender and obliquely-straight socius, and by the valva, in which the ventral half is naked in its basal half and the costa bears an oblong projection near middle.

Description. Adult ( Fig. 2 View FIGURES 1 – 7 ): Wing expanse 13.0–15.0 mm. Head white. Antenna with scape white, flagellum pale brown. Labial palpus white, tinged with pale yellow ventrally. Thorax and tegula white mottled pale yellow. Forewing with apex narrowly pointed, termen obliquely straight; white with scattered brown scales; costal margin with basal 1/6 dark brown; small brown spot at 2/5 of fold and at tornus respectively; cilia whitish yellow except distal 1/4 black. Hindwing greyish yellow; cilia silvery white except basal 1/4 grey. Legs white; tarsi pale yellow, black at apex.

Male genitalia ( Fig. 9 View FIGURES 8 – 11 ): Socius slender, with sclerotized and pointed apex, long horn shaped. Tuba analis membranous, truncate on caudal margin. Ventral plate of gnathos somewhat spade-shaped, narrowly rounded apically. Valva broad; basal half naked ventrally, greatly projecting outward and forming blunt angle at middle, distal half finely setose, gradually narrowed to rounded apex, with gently arched ventral margin; costa with an oblong projection near middle, greatly curved medially. Sacculus narrow, indistinct. Saccus with posterior 2/5 broadly U-shaped, anterior 2/5 triangular. Phallus slightly longer than saccus, slender, dentate distally.

Female: Unknown.

Distribution. China ( Taiwan).

Etymology. The specific name is derived from the Latin prefix parti -, and nudus, referring to the valva with ventral portion naked in basal half.
