Type material.

Holotype: ♂ (IZCAS-Ar44685), China, Yunnan: Chuxiong City, Wuding County, Mao Street, Xianren Cave, 25.4655°N, 102.1740°E, ca 2066 m, 18.VI.2010, C. Wang, Q. Zhao and Y. Lin leg. Paratypes: 10♀ (IZCAS-Ar44686-Ar44695), same data as holotype.

Diagnosis.

Troglohnia wuding sp. nov. can be distinguished from T. qiubei sp. nov. by the male ventral retrolateral tibial apophysis strongly curved and wider than dorsal retrolateral tibial apophysis (Fig. 15B) [vs almost straight and as wide as dorsal retrolateral tibial apophysis (Fig. 12B)], embolic tooth terminal terminal finger-shaped (Fig. 15A) [vs flat (Fig. 12A)], process on anterior 3/5 of tegulum (arrowed in Fig. 15A) [vs on anterior 1/3 (arrowed in Fig. 12A)] and female can be distinguished by the diameter of secondary spermathecae almost as same as diameter of primary spermathecae (Fig. 16B) [vs less than diameter of primary spermathecae (Fig. 13B)], distance between primary spermathecae and secondary spermathecae less than half of diameter of secondary spermathecae (Fig. 16B) [vs more than half of diameter (Fig. 13B)], secondary spermathecae separated by ~ 1 × diameter (Fig. 16B) [vs 1.5 × (Fig. 13B)] and fertilization ducts pointing to 9:00 o’clock position (Fig. 16B) [vs 7:30 o’clock position (Fig. 13B)].

Ventral opisthosoma grey, anterior and middle part with brown patterns. Spinnerets surrounded by brown rings. Spinnerets base brown and tip white.

Palp (Figs 15A, B, 17C). Patellar apophysis with wide base and narrowed tip, the narrowed tip as long as the wide base. Ventral retrolateral tibial apophysis curved, almost 1/2 × longer than dorsal retrolateral tibial apophysis and 2 × wider than the dorsal retrolateral tibial apophysis. Cymbium 1.5 × longer than wide. Cymbial furrow almost as long as cymbium. Bulb almost oval. A triangle process presents at the prolateral edge of tegulum. Medium of tegulum with oval membranous area. Length of stalk of conductor almost half of total conductor length. Embolic tooth terminal blunt. Embolus slender and whip-shaped.

Female (paratype IZCAS-Ar44695; Figs 16A, B, 18D, 19D, 20H). Total body length 2.26. Carapace 0.93 long, 0.72 wide; opisthosoma 1.33 long, 0.90 wide.
