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 View Figure 15 ) [vs almost straight and as wide as dorsal retrolateral tibial apophysis (Fig. 12B View Figure 12 )], embolic tooth terminal terminal finger-shaped (Fig. 15A View Figure 15 ) [vs flat (Fig. 12A View Figure 12 )], process on anterior 3/5 of tegulum (arrowed in Fig. 15A View Figure 15 ) [vs on anterior 1/3 (arrowed in Fig. 12A View Figure 12 )] and female can be distinguished by the diameter of secondary spermathecae almost as same as diameter of primary spermathecae (Fig. 16B View Figure 16 ) [vs less than diameter of primary spermathecae (Fig. 13B View Figure 13 )], distance between primary spermathecae and secondary spermathecae less than half of diameter of secondary spermathecae (Fig. 16B View Figure 16 ) [vs more than half of diameter (Fig. 13B View Figure 13 )], secondary spermathecae separated by ~ 1 × diameter (Fig. 16B View Figure 16 ) [vs 1.5 × (Fig. 13B View Figure 13 )] and fertilization ducts pointing to 9:00 o’clock position (Fig. 16B View Figure 16 ) [vs 7:30 o’clock position (Fig. 13B View Figure 13 )].

Palp (Figs 15A, B View Figure 15 , 17C View Figure 17 ). 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.
