Material examined.

Holotype: ♂, China, Sichuan Province, Chongzhou City, Anzihe Nature Reserve , 1595 m, 30 July 2016, coll. Bin Yan. Paratypes: 6♂♂ 4♀♀, same data as holotype ; 1♂, same data as holotype except, 1687 m, 31 July 2016, at light. All type species deposited in Institute of Entomology , Guizhou University, Guiyang, China (GUGC) and one male paratype in BMNH .

Description.

Length. Male: 5.5-6.0 mm; female: 5.6-6.0 mm.

Color pale yellow. Ocelli red or orange-yellow; eyes reddish brown laterally. Thorax with a brown band extending from behind each eye on pronotum, onto mesonotum and continued onto inner margin of clavus and diagonally across wing to costal margin. Forewing brownish hyaline distally. Legs with fore tibiae and tarsi black.

Male genitalia. Genitalia as in generic description with aedeagus (Fig. 2g-i ) broad in lateral view with shaft constricted and narrowed distally, with a short ventral process arising medially from ventral surface and a pair of short slightly more elongate processes arising subapically from dorsal surface and apically, all densely covered with micro-spines, lamellate medial lobe from dorsal surface basally.

Female genitalia. Sternite VII, in ventral view, with length approximately equal to width; posterior margin convex medially.
