Halter yellow.

Abdomen ( Fig. 27 View FIGURES 23 – 29 ) yellow; tergites 2–5 with brownish posterior margin. Male genitalia ( Figs. 28–33 View FIGURES 23 – 29 View FIGURES 30 – 33 ): Protandrium circular; surstylus very broad in both lateral and posterior view, with a ventrally oriented sharp process subapically, with long hairs; hypandrium W-shaped, or H-shaped with lateral arms divergent distally, hypandrial apodemes small; gonopod with an inward curved triangular process and a subuliform process; aedeagus columniform with a deep apical incision in ventral view, and with a blunt dentation dorsally in lateral view; aedeagal apodeme slightly shorter than aedeagus.

Type material. Holotype male ( CAU), CHINA, Guizhou Province: Suiyang, Kuankuoshui Nature Reserve (N 28°14ʹ, E 107°11ʹ, 1400 m), 15. VIII. 2010, Guoquan Wang. Paratypes: CHINA, Guizhou Province: 4 males ( CAU), same data as holotype; 1 male ( CAU), same place as holotype, 13. VIII. 2010, Sipei Liu.

Distribution. China (Guizhou).

Remarks. This species is somewhat similar to H. ( H.) bispinalis from Zhejiang. But it can be separated from the latter by the surstylus very broad and the hypandrium H-shaped. In bispinalis , the surstylus is finger-like, the hypandrium is nearly Y-shaped ( Yang, Hu and Zhu, 2001).

Etymology. The species is named after the type locality Kuankuoshui Nature Reserve.
