Figs 14A, B , 18C , 19C , 20E, F , 30 Type material. Holotype : ♀ (IZCAS-Ar44683), China, Yunnan: Baoshan City, Shidian County, Bailang Town, Xianren Cave, 24.6536°N , 99.2645°E , ca 1987 m, 29.VII.2010, C. Wang, Q. Zhao and Y. Lin leg. Paratype : 1♀ (IZCAS-Ar44684), same data as holotype. Diagnosis. Troglohnia shidian sp. nov. can be distinguished from those of T. dafang sp. nov. by the ratio of diameter of secondary spermathecae to length of branched shorter copulatory ducts almost 1:1 (Fig. 14B ) [vs 1:2 (Fig. 11B )], primary spermathecae oval, separated by more than 2 x diameters (Fig. 14B ) [vs elongate bean-shaped, separated by less than one diameter (Fig. 11B )], diameter of primary spermathecae ~ 1.2 x diameters of secondary spermathecae (Fig. 14B ) [vs 2 x (Fig. 11B )], distance between primary spermathecae and secondary spermathecae ~ 1 x diameter of secondary spermathecae (Fig. 14B ) [vs 2 x (Fig. 11B )] and secondary spermathecae separated by ~ 3 x diameters (Fig. 14B ) [vs 4 x (Fig. 11B )]. Description. Female (holotype; Figs 14A, B , 18C , 19C , 20E, F ). Total body length 3.75. Carapace 1.74 long, 1.33 wide; opisthosoma 2.01 long, 1.44 wide. AER straight and PER procurved slightly. Eye sizes and interdistances: AME 0.04, ALE 0.08, PME 0.07, PLE 0.09; AME-AME 0.03, AME-ALE 0.03, PME-PME 0.11, PME-PLE 0.06, ALE-PLE 0.02. MOA 0.17 long, front width 0.10, back width 0.24.

Coloration (Fig. 20E, F ). Carapace yellow, with indistinct dark yellow radial grooves, middle region with shield-shaped brown band, margin with brown pattern. Fovea longitudinal, reddish-brown. Chelicerae, labium, gnathocoxae, and sternum yellow. Sternum with brown marking. Legs yellow. Opisthosoma oval, grey, middle of anteriorly and laterally with rod-shaped brown patterns, middle of posteriorly with inverted V-shaped brown patterns; venter with brown patterns and brown ring around spinnerets. Spinnerets base brown and tip white. Epigyne (Figs 14A, B , 18C , 19C ). Epigynal plate 1.3 x wider than long. Hoods 5 x depth than width. The posterior edge of copulatory openings touching, slightly curved. The width of thick copulatory ducts base 3 x wider than the thinner part. The branched shorter copulatory ducts connected to secondary spermathecae, the other connected to the primary spermathecae. Primary spermathecae oval, longer than the width of the secondary spermathecae. Fertilization ducts directed at 9:00 o'clock position from spermathecae. Variation. Second paratype female: total body length 3.47, carapace 1.35 long, 1.01 wide, opisthosoma 2.12 long, 1.42 wide. Etymology. The specific epithet refers to the type locality; noun in apposition. Distribution. Known only from the type locality (Fig. 30 ).
