Type material.

Holotype ♂: China: Xinjiang, Ili Kazakh Autonomous Prefecture: Xinyuan County, N43°21'58", E84°21'34", 2010 m, 12.VIII.2013, J. Liu. Paratype: 1♀, same data as holotype.

Etymology.

The specific name is a patronym in honor of the collector Jincheng Liu; noun (name) in genitive case.

Diagnosis.

The male can be easily distinguished from all the other Pireneitega species, except Pireneitega luniformis , by having a long and narrow conductor, and can be distinguished from this species by the blunt tip of the patellar apophysis (the tapering tip of conductor and the patellar apophysis in Pireneitega luniformis ) (cf. Fig. 10; Zhu and Wang 1994: figs 7-8). The female can be distinguished from all other Pireneitega species, except Pireneitega major (Kroneberg, 1875) by having the nearly trapezoidal epigynal atrium, and can be distinguished from this species by the abrupt tip of epigynal teeth (the pointed tip of teeth in Pireneitega major ) (cf. Fig. 11 A–B; Kroneberg 1875: fig. 6).
