Etymology.

The specific name refers to the type locality; adjective.

Diagnosis.

The male can be distinguished from all other Pireneitega species, except Pireneitega tianchiensis, by having narrow tibia and tarsus. From Pireneitega tianchiensis, it can be distinguished by the nearly trapezoidal embolic base (while Pireneitega tianchiensis has the nearly fingernail-shaped embolic base) (cf. Figs 1 and 12; Wang et al. 1990: figs 81-83). The female can be distinguished from all other Pireneitega species, except Pireneitega tianchiensis, by having the weakly sclerotized tip of septum and the closely spaced copulatory opening. From Pireneitega tianchiensis, it can be distinguished by the sharply narrowed epigynal teeth (while in Pireneitega tianchiensis the epigynal teeth are broad and nearly horn-shaped) (cf. Figs 2 A–B and 13 A–B; Wang et al. 1990: figs 84-85).
