Pireneitega tianchiensis : 1♀1♂ (Figs 12-13): China: Xinjiang, Changji Hui Autonomous Prefecture: Fukang City, Crater Lake Scenic Spot (in Chinese: Tianchi), N43°54'05", E88°07'29", 1878 m, 16.VII.2013, Z. Yao and Z. Zhao.

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).
