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 )].

MOA 0.18 long, front width 0.12, back width 0.17. Clypeus 0.16 high. Chelicerae with two promarginal and three retromarginal teeth. Leg measurements: I 4.36 (1.27, 0.43, 1.00, 0.93, 0.73); II 4.19 (1.25, 0.41, 0.94, 0.89, 0.70); III 3.81 (1.11, 0.40, 0.81, 0.86, 0.63); IV 4.73 (1.30, 0.41, 1.14, 1.12, 0.76). Leg spination: femora I-III d1; tibiae I p1 d1, II d2, III p1 d2 r1 v2, IV r1 v2; metatarsi III-IV p1 r1 v2.
Coloration (Fig. 20G View Figure 20 ). Carapace yellowish, middle region with elongated brown band, margin with brown pattern. Fovea longitudinal, reddish-brown. Chelicerae, labium, gnathocoxae, and sternum yellow. Sternum with brown marginal marking. Legs yellow. Dorsal opisthosoma oval, grey, middle of anteriorly and laterally with rod-shaped brown patterns, middle of posteriorly with dotted brown patterns. 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 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. 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 View Figure 16 , 18D View Figure 18 , 19D View Figure 19 , 20H View Figure 20 ). Total body length 2.26. Carapace 0.93 long, 0.72 wide; opisthosoma 1.33 long, 0.90 wide. Eye sizes and interdistances: AME 0.05, ALE 0.07, PME 0.07, PLE 0.08; AME-AME 0.02, AME-ALE 0.03, PME-PME 0.08, PME-PLE 0.04, ALE-PLE 0.02. MOA 0.18 long, front width 0.07, back width 0.19. Clypeus 0.13 high. Chelicerae with three promarginal and four retromarginal teeth. Leg measurements: I 3.55 (1.03, 0.37, 0.81, 0.77, 0.57); II 3.45 (1.02, 0.36, 0.76, 0.75, 0.56); III 3.15 (0.84, 0.35, 0.70, 0.74, 0.52); IV 4.03 (1.09, 0.39, 0.95, 0.99, 0.61).

Coloration (Fig. 20H View Figure 20 ). As in male but carapace with shield-shaped brown band at middle.
Epigyne (Figs 16A, B View Figure 16 , 18D View Figure 18 , 19D View Figure 19 ). Epigynal plate 1.35 × wider than long. Hoods 3 × depth than width. Copulatory openings arc-shaped, facing each other, circular. The width of thick copulatory ducts base 2 × wider than the thinner part. The branched shorter copulatory ducts connected to the secondary spermathecae, the other connected to the primary spermathecae. Primary spermathecae bean-shaped, almost as wide as the secondary spermathecae. Fertilization ducts directed at 9:00 o’clock position from spermathecae.
