Type material. Holotype 6 GoogleMaps (IZCAS-Ar34091): Qixian Cave   GoogleMaps (N25°12.225’, E106°07.085’, 934 m), Wangmo County, Southwest   GoogleMaps Guizhou Autonomous Prefecture, Guizhou, China, 14. IV. 2018, Z. Chen and J. Liu leg. Paratype: 1♀ (IZCAS-Ar34092): same data as holotype GoogleMaps .

Etymology. The specific name refers to the type locality, Qixian Cave; adjective.

Diagnosis. The male can be distinguished from the similar T. yumiganensis sp. n. by the lack of any lamella on conductor vs. having a lamella and without spine next to RTA. From the similar T. liangensis sp. n. by the patellar apophysis longer than patellar length vs. less than 1/2 the patellar length, tip of the conductor pointed to anteriorly vs. posteriorly. From the similar T. tortus by the tip of the patellar apophysis pointed vs. blunt, and cymbial furrow length 1/2 the length of the cymbium vs. 2/3 the length of the cymbium ( Fig. 8 View FIGURE 8 B–C). Females can be distinguished from the similar T. liangensis sp. n. by the posterior margin of epigynal atrium rectangular vs. oval, epigynal teeth located next to atrium lateral margins while in other congeners located above atrium ( Fig. 9 View FIGURE 9 A–B).

Description. Male (holotype, IZCAS-Ar34091): Total length 3.83. Carapace 1.95 long, 1.13 wide. Abdomen 1.88 long, 1.26 wide. All eyes absent. Leg pale. Leg measurements: I: 8.14 (2.26, 2.74, 1.88, 1.26); II: 7.35 (2.19, 2.34, 1.56, 1.26); III: 7.11 (2.03, 2.03, 1.79, 1.26); IV: 9.09 (2.51, 2.81, 2.51, 1.26). Abdomen and spinnerets brown. Palp: patellar apophysis longer than patellar length, blunt tip; VTA extending beyond tibia, with blunt tip; length of RTA about 1.5 times shorter than VTA; cymbial furrow about 1/2 the length of the cymbium; embolus beginning at 6 o’clock position; conductor ducts 3 times wider than spermathecal width ( Fig. 8 View FIGURE 8 A–C).

Female (paratype, IZCAS-Ar34092): Total length 5.15. Carapace 2.34 long, 1.41 wide. Abdomen 2.81 long, 1.88 wide. Leg measurements: I: 8.46 (2.59, 2.81, 1.72, 1.34); II: 7.83 (2.50, 2.34, 1.71, 1.28); III: 7.42 (2.19, 2.42, 1.56, 1.25); IV: 9.85 (2.97, 2.97, 2.50, 1.41). Epigyne: atrium occupying less than 1/5 of the epigynal plate, situated at the posteriorly; the posterior margin of epigynal atrium rectangular; teeth 6 times shorter than atrial width, 2 times longer than width, located medio-laterally, spaced of each other by about 5 lengths; the widest parts of copulatory ducts 3 times wider than spermathecal width ( Fig. 9 View FIGURE 9 A–B).
