Type material.

Holotype ♀: China: Xinjiang, Ili Kazakh Autonomous Prefecture: Tacheng (Tarbagatay) Prefecture, Hoboksar Mongol Autonomous County, Songshugou, N46°59'21", E85°57'20", 1858 m, 29.VII.2013, Z. Yao and Z. Zhao. Paratype: 1♀, same data as holotype.

Etymology.

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

Diagnosis.

The female can be distinguished from all other Pireneitega species, except Pireneitega burqinensis sp. n., Pireneitega fuyunensis sp. n. and Pireneitega tianchiensis , by having the weakly sclerotized tip of septum. It can be distinguished from these three species by the nearly rectangular epigynal atrium (while Pireneitega burqinensis sp. n. has a nearly triangular atrium; and Pireneitega tianchiensis and Pireneitega fuyunensis sp. n., large and nearly square-shaped atrium) (cf. Figs 2 A–B, 4 A–B, 6 A–B and 16 A–B; Wang et al. 1990: figs 84-85).

Female (holotype): Total length 12.25. Carapace 5.00 long, 4.25 wide. Abdomen 7.25 long, 4.50 wide. Eye sizes and interdistances: AME 0.23, ALE 0.27, PME 0.23, PLE 0.25; AME-AME 0.12, AME-ALE 0.08, PME-PME 0.13, PME-PLE 0.25.
