( Figs. 7–13 View FIGURES 1 – 8 View FIGURES 9 – 10 View FIGURES 11 – 17 )

Holotype Ƥ: China, Ningxia, Guyuan City, Liupanshan, Laolongtan Forestry Centre, 13. VII. 2009, Zhenhua Zu.

Paratypes: 4 3, China, Ningxia, Guyuan City, Liupanshan, Qiuqianjia Forestry Centre, 12. VII. 2009, Zhenhua Zu.

Etymology. The specific name liupanshanense is the Neolatin neuter adjective, with reference to the region from which the type –specimens were collected.

Recognition. This species can be distinguished from the similar P. ignavum Turner, 1908 and all other members of the genus by the combination of the following characters: propodeal dorsum without furrow and lateral carina; sternum VIII ( Fig. 13 View FIGURES 11 – 17 ) somewhat depressed basally and not depressed apically, somewhat protruding medially at the apex.

Description. Female body length 9.5 mm, male body length 7.0–8.5 mm. Body black; palpi, mandible apically, and outer margin of tegula dark brown; body with long silvery setae, those on clypeus and ventral frons comparatively denser and somewhat appressed, setae on apical band of each gastral tergum shorter than those on other portions and unobvious medially, setae erect on the vertex, scutum, and tergum I; fore wing ( Fig. 14 View FIGURES 11 – 17 ) with three submarginal cells.

Ƥ ( Figs. 9 View FIGURES 9 – 10 , 11 & 14 View FIGURES 11 – 17 ). Head: Frons coarse and with dense punctures, PD>PIS, interspaces between punctures dull and microcoriaceous, frons dorsally with medial longitudinal furrow, ventrally with long medial longitudinal carina, carina almost extending to antennal socket; vertex with sparse punctures, PD<PIS, interspaces between punctures somewhat smooth; eye incision shallow and pointed apically; clypeus ( Fig. 11 View FIGURES 11 – 17 ) protuberated medially, punctures on clypeus concealed by appressed setae, clypeal ventral margin almost transversely protruding in middle; apex of each antennal flagellomere slightly wider than its base; HW: HL: IOD V=149: 39: 63; IOD S =63: 56; OOD: OD: POD= 10: 10: 10; flagellomere I= 28; flagellomere I, II, III= 28: 21: 21.

Thorax: Thorax densely, almost uniformly punctate, PIS<PD, but punctures on middle portion of scutum, scutellum and metanotum comparatively sparser, PIS>PD, interspaces between punctures smooth; scutum basally with four short, shallow, and narrow medial longitudinal furrows; mesosternum with one thin and short longitudinal carina; punctures on mesopleuron similar to those on lateral portion of scutum; propodeum without lateral carina, propodeal dorsum punctate, with more or less curved oblique–longitudinal ridges from base to apex, medially with longitudinal carina, carina basally with a few minute and oblique offshoots, apically evanescent and with transversely curved ridges; interface between propodeal dorsum and pleuron not ditched; propodeal pleuron with dense punctures, interspaces between punctures smooth; propodeal hindface with narrow, deep medial furrow, laterally with curved transverse ridges.

Gaster: Each gastral segment dull, densely punctate, punctures comparatively smaller than those on head and thorax, interspaces between punctures smooth, translucent gastral apical bands inconspicuous.

3 ( Figs. 10 View FIGURES 9 – 10 , 12–13 & 15–17 View FIGURES 11 – 17 ). Similar to female; mainly differing from female as follows: ventral margin of clypeus ( Fig. 12 View FIGURES 11 – 17 ) toothed somewhat bluntly in the middle; medial longitudinal carina on propodeal dorsum longer than that in female, and with more oblique offshoots; HW: HL: IOD V= 135: 38: 55, IOD S= 55: 50, OOD: OD: POD= 10: 9: 10; flagellomere I= 23; flagellomere I, II, III= 23: 19: 19; sternum VIII ( Fig. 13 View FIGURES 11 – 17 ) somewhat depressed basally and not depressed apically, somewhat protruding medially at the apex, genitalia: Figs. 11–13 View FIGURES 11 – 17 .
