Paratachycines (Hemitachycines) xiai sp. n.

( Figs. 5–7 )

Type material. Holotype ɗ, Shandong (Jinan longdong), alt. 500–700m; Paratype 1ɗ,1Ψ, Henan (Songxian Baiyunshan), 9–20.VIII.1996, leg. Liu, Zu-Yao et al.; 1Ψ, HenanFuniushanalt. 1400–1700m 2-VIII-2004, Tang et al.

Diagnosis. Male. Head with fastigium of vertex divided into two conical tubercles. Legs long and slender; Fore femora about 1.6–1.7 times as long as the pronotum, beneath unarmed, the internal knee lobe with a short spine, external knee lobe with 1 long movable spur; fore tibiae beneath with 2 internal and 2 external spurs, a small median spine between the paired apical spurs. Mid femora with a spur on the internal and external knee lobe; mid tibiae beneath with 2 external and 1–2 internal spurs, a small median spine between the paired apical spurs. Hind femora beneath on inside armed with 3–4 spines, hind tibiae above on the each side with 60–68 spines, which grouped in series, super internal spur of hind tibiae shorter than the metatarsus, tarsus with bristles beneath (fig.5). Male genitalia as figs. 5–6.

Female. Subgenital plate as fig.7, ovipositor as long as the pronotum.

Measurements (in mm): length of body 12.0, pronotum 4.5–4.8, fore femora 7.5–8.0, hind femora 14.0–15.5, ovipositor 9.0mm.
