Type material. Holotype ♂ (IZCAS-Ar34096): Yumigan Cave (N24°38.965’, E105°09.754’, 1549 m), Tianyakou Village, Longlin County, Baise City, Guangxi Zhuang Autonomous Region, China, 19. IV. 2018, Z. Chen and J. Liu leg. Paratypes: 1♀ (IZCAS-Ar34097): same data as in holotype; 1♀ (IZCAS-Ar34098): same cave, 14–15. XII. 2012, Z. Zhao and Z. Chen leg.; 3♀♀ (IZCAS-Ar34099-Ar34101): same cave, 5. XII. 2017, Z. Chen leg.
Etymology. The specific name refers to the type locality, Yumigan Cave; adjective.
Diagnosis. The male can be distinguished from T. qixianensis sp. n. by having a large lamella on conductor, small RTA, and a black spine next to RTA. From the similar T. tortus by the blunt tip of the patellar apophysis and a short cymbial furrow (1/2 the length of the cymbium vs. 2/3 the length of the cymbium). From the similar T. liangensis sp. n. by the long patellar apophysis and a narrow conductor (Fig. 12 B–C). Females can be distinguished from T. nongchiensis sp. n. by the posterior margin of epigynal atrium belt-shaped vs. triangular (Fig. 13 A–B).
Description. Male (holotype, IZCAS-Ar34096): Total length 5.51. Carapace 2.69 long, 1.97 wide. Abdomen 2.82 long, 1.72 wide. Cervical groove and radial furrows pronounced. Eyes reduced, with 6 spots; anterior lateral spots and posterior lateral spots large than other spots. Legs pale. Leg measurements: I: 11.09 (2.97, 3.59, 2.81, 1.72); II: 10.63 (2.81, 3.44, 2.66, 1.72); III: 9.49 (2.51, 2.66, 2.65, 1.67); IV: 13.15 (3.13, 4.22, 3.91, 1.89). Abdomen milky white. Spinnerets milky white. Palp: patellar apophysis shorter than length of patella and with a blunt tip; VTA wide; RTA about 1/3 the length of the cymbium; distal part with black spine next to RTA; cymbial furrow 1/2 the length of the cymbium; embolus beginning at 7 o’clock position; conductor pointed to obliquely up with a large lamella (Fig. 12 A–C).
Female (paratype, IZCAS-Ar34097): Total length 6.01. Carapace 3.25 long, 1.76 wide. Abdomen 2.76 long,
2.01 wide. Leg measurements: I: 10.41 (2.96, 3.41, 2.40, 1.64); II: 9.99 (2.81, 3.13, 2.49, 1.56); III: 9.31 (2.49, 2.84, 2.48, 1.50); IV: 12.40 (3.21, 3.79, 3.61, 1.79). Epigyne: atrium located posteriorly, occupying about 1/4 of the epigynal plate; epigynal teeth short, located anteriorly, with the width as its length, spaced of each other by 12 lengths; copulatory duct like 2 folded sacs and copulatory ducts overlapped of each other at their tips; spermathecae brown (Fig. 13 A–B).
Distribution. China (Guangxi) (Fig. 14).
