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).
