Female. Unknown. Holotype male, Hebei: Yuxian, Xiaowutai National Nature Reserve, Chiyanbaogou, 2004. V. 29, Xingyue Liu (CAU). Etymology. The species is named after the region of its origin, Hebei. Remarks. The new species is similar to P. henanensis Yang, An and Gao from Henan, but can be separated from the latter by the mid tibia with 1 long spine­like apical spur and vertex with 1 vt.

Male genitalia (Figs. 5 – 7): Left and right epandrial lamellae narrowly connected basally; left epandrial lamella narrow, surstylus not distinctly separated, nearly acute apically with 4 long lateral hairs; right epandrial lamella wide with separated surstylus short and nearly acute apically; left cercus slightly longer than right cercus, right cercus with wide base. Female. Unknown. Holotype male, Hebei: Yuxian, Xiaowutai National Nature Reserve, Huichuan, 2004. V. 31, Xingyue Liu (CAU). Paratypes 2 males, same data as holotype (CAU). Etymology. The species is named for the acute surstyli. Remarks. The new species is similar to P. acuminatus Saigusa and Yang from Henan, but can be distinguished from the latter by the femora without the dark apical portions and the mid tibia without the distinct apical spur. In P. acuminatus, the mid and hind femora have the black apical portions, and the mid tibia has the short obtuse spur (Yang & Saigusa, 2002). The new species belongs to the P. pallipes species group.	en	Yang, Ding, Li, Weihai (2005): New species of Platypalpus from Hebei province, China (Diptera: Empididae).

Female. Body length 2.4 – 3.2 mm, wing length 4.5 – 4.6 mm. Holotype male, Hebei: Yuxian, Xiaowutai National Nature Reserve, Huichuan, 2004. V. 31, Xingyue Liu (CAU). Paratypes 2 females, same data as holotype (CAU). Etymology. The species is named after the region of its origin, Xiaowutai. Remarks. The new species is similar to P. hui Yang, An and Gao from Henan, but can be separated from the latter by the mid femur slightly thickened (1.4 times as wide as hind femur) and mid tibia without distinct apical spur.
