Description of the female ( Figs. 1–2 ). Forewing length 7.0– 7.5 mm. Posterior margin of sternum 7 produced in bidentate subgenital plate, apices are claw-like in lateral view; the posterior portion is black, contrasting with the rest of the plate that is pale brown. Sternum 8 with two very small, rounded sclerites laterally to the genital opening, and a transverse band that occupies the posterior third of the segment.

Remarks. This species was described from Zhejiang Province, previously known only from the male holotype (Yang & Li 2016). New for Guangxi, our male specimens agree with the original description but with some variation. The epiproct apex has a shallow anterior indentation which is not indicated in Sivec et al. (2008), and the down projecting spine is stouter ( Figs. 3–4 ) than illustrated for the holotype. In addition, scales of the tergum 10 central plate are relatively indistinct ( Fig. 5 ).
