Type material.

Holotype ♀ ( HBU-WM-24-004 ), 1 ♀ paratype ( HBU-WM- 24-005 ): China: Yunnan Province, Zhaotong City, Weixin County, Houshan mountain , 27.8147 ° N, 104.8050 ° E, elevation: 1363 m, 1. X. 2018, C. F. Tao and H. Y. Chen leg. GoogleMaps

Etymology.

The specific name is dedicated to Ms Qiqi Wang, at the desire of Caifu Tao, who provided the holotype; a noun (name) in genitive case.

Diagnosis.

The females of Yunguirius wangqiqiae sp. nov. resemble those of Y. subterebratus and Y. terebratus in that they have long blind sacs of the copulatory ducts, approximately equal to the length of the openings of the copulatory ducts, while the copulatory ducts are ventrally connected with the spermathecae (Figs 1 B View Figure 1 , 6 B View Figure 6 ; fig. 245 B in Zhu et al. 2017). In contrast, other species such as Y. duoge , Y. parvus sp. nov., Y. trigonus sp. nov. and Y. xiangding have short blind sacs, shorter than the length of the openings of the copulatory ducts (Fig. 2 B View Figure 2 , 4 B View Figure 4 ; figs 2 B, 4 B in Li et al. 2023), or have long blind sacs but the copulatory ducts are dorsally connected with the spermathecae such as Y. ornatus and Y. xiannushanensis sp. nov. (Fig. 8 View Figure 8 ; fig. 3 B in Li et al. 2023). However, Y. wangqiqiae sp. nov. can be distinguished from the latter by the following characteristics: 1) the atrium is bowl-shaped, wider than long, and lacks the fold (Fig. 6 A View Figure 6 ), versus being trapezoidal in Y. subterebratus (fig. 245 A in Zhu et al. 2017) or being subrounded, with the width roughly equal to the length, and presenting the fold in Y. terebratus (Fig. 1 A View Figure 1 ); 2) the copulatory ducts featuring only the prototype of the secondary layers (Fig. 6 B View Figure 6 ), versus possessing advanced secondary layers in Y. terebratus (Fig. 1 B View Figure 1 ); 3) the spermathecal stalks are long and extend laterally with conch-shaped distal ends (Fig. 6 B View Figure 6 ), versus being extremely short in Y. subterebratus (fig. 245 B in Zhu et al. 2017), and in Y. terebratus , they are long but extend obliquely upward, with large and round distal ends (Fig. 1 B View Figure 1 ).

Description.

Female (holotype) (Fig. 7 View Figure 7 ). Carapace reddish brown. Cervical and radial groove distinct. Cephalic region moderately raised and wide, lateral margin with distinct furrows. Chelicerae with 3 promarginal teeth and 2 retromarginal teeth, condyle red. Sternum longer than wide. Abdomen pale yellow, with 5 chevron-shaped patterns, covered by hairs. Legs red. Total length 14.48. Carapace 7.51 long, 5.03 wide, cephalic region 4.28 wide. Abdomen 7.95 long, 4.80 wide. Eye size and interdistance: AME 0.22, ALE 0.31, PME 0.32, PLE 0.38; AME – AME 0.16, AME – ALE 0.20, AME – PME 0.19, ALE – PLE 0.11, PME – PME 0.09, PME – PLE 0.45. Leg measurements: Leg I 19.71 (2.53, 0.93, 4.98, 2.11, 4.08, 3.47, 1.96), leg II 17.82 (2.21, 0.86, 4.44, 1.93, 3.23, 3.28, 2.11), leg III 14.82 (2.00, 0.92, 3.67, 1.73, 2.44, 2.85, 1.61), leg IV 19.73 (2.31, 1.11, 4.87, 1.87, 3.84, 4.13, 1.84). Epigyne (Fig. 6 View Figure 6 ). Epigynal teeth absent. Atrium large, bowl-shaped, anterior margin incomplete. Posterior epigynal sclerite weakly sclerotized and opalescent. Hoods weak, situated laterally. Fold absent. Copulatory ducts broad, laterally originated, slightly folded, with the prototype of the secondary layers; blind sacs long and with distal tips overlapped. Spermathecal base small; spermathecal stalk long, with distal tip conch-shaped and extended laterally; spermathecal head only remaining a sclerotized end. Fertilization ducts posteriorly situated.
