Type material.

Holotype ♂: China: Shaanxi: Huayin Prefecture: Mt. Huashan, Duyukou Village, 34°31'42"N, 110°07'22"E, 530 m, 30.IX.2013, Y. Li and J. Liu. Paratypes: 1♂, same data as holotype; 4♀1♂, same area, 34°32'46"N, 110°07'06"E, 536 m, 2.X.2016, Z. Zhao and X. Zhang.

Etymology.

The specific name refers to the type locality; adjective.

Diagnosis.

The male can be distinguished from all other Pireneitega species except P. luniformis (Zhu & Wang, 1994) by having a tapering conductor tip and longer cymbial furrow. From P. luniformis , it can be distinguished by the elongate embolus base and the larger diameter of the conductor’s loop, approximately six times the width of the conductor (vs the small embolus base and the small diameter of the conductor’s loop in P. luniformis ) (Fig. 1; Zhu and Wang 1994: figs 7-8). The female can be distinguished from all other Pireneitega species except P. luniformis by having short copulatory ducts and long epigynal teeth, subequal to the length of the atrium. From P. luniformis , it can be distinguished by the longer septum (vs the short septum in P. luniformis ) (Fig. 2; Zhu and Wang 1994: figs 5-6).

Leg measurements: I: 10.25 (3.00, 3.50, 2.25, 1.50); II: 8.30 (2.50, 3.00, 1.80, 1.00); III: 8.00 (2.40, 2.75, 1.85, 1.00); IV: 11.55 (3.50, 3.75, 3.00, 1.30). Carapace brown. Abdomen black with yellow spots and herringbone pattern. Epigyne as in Fig. 2 A–B: epigynal teeth long; septum long with weakly sclerotized tip; atrium with well delimited posterior margin, about 0.6 times longer than wide, about two times longer and wider than septum; copulatory opening distinct; receptacle long, about three times longer than wide, separated by two diameters; copulatory ducts with three parts, the basal part running from receptacle posteriorly (Bd), median part running anteriorly (Md), and terminal part (Td) running posteriorly and leading to copulatory opening; median part as wide as terminal and two times longer than basal part; median part separated; hoods indistinct.
