Etymology.

The specific name refers to the type locality; adjective.

Diagnosis.

The male can be distinguished from all other Pireneitega species except P. involuta , P. liansui and P. triglochinata by having a broad conductor, the width of the conductor about 1/5 of loop diameter. From P. involuta it can be distinguished by the bifurcate tip of the patellar apophysis (vs a tapering tip in P. involuta and P. triglochinata ). From P. liansui it can be distinguished by the short cymbial furrow, about 0.3 times the length of the cymbium (vs a long cymbial furrow in P. liansui , more than half the length of the cymbium) (Figs 3, 7, 9; Wang et al. 1990: figs 13-15, 18-19). The female can be distinguished from all other Pireneitega species except P. xinping Zhang, Zhu & Song, 2002 by having bent and narrow epigynal teeth, a broad atrium and sclerotized tip of the septum. From P. xinping it can be distinguished by a long receptacle, about four times longer than wide (vs a straight and short receptacle in P. xinping , about two times longer than wide) (Fig. 10; Zhang et al. 2002: figs 7-8).
