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 View Figure 14 ) [vs 1:2 (Fig. 11B View Figure 11 )], primary spermathecae oval, separated by more than 2 × diameters (Fig. 14B View Figure 14 ) [vs elongate bean-shaped, separated by less than one diameter (Fig. 11B View Figure 11 )], diameter of primary spermathecae ~ 1.2 × diameters of secondary spermathecae (Fig. 14B View Figure 14 ) [vs 2 × (Fig. 11B View Figure 11 )], distance between primary spermathecae and secondary spermathecae ~ 1 × diameter of secondary spermathecae (Fig. 14B View Figure 14 ) [vs 2 × (Fig. 11B View Figure 11 )] and secondary spermathecae separated by ~ 3 × diameters (Fig. 14B View Figure 14 ) [vs 4 × (Fig. 11B View Figure 11 )].

Description.

Female (holotype; Figs 14A, B View Figure 14 , 18C View Figure 18 , 19C View Figure 19 , 20E, F View Figure 20 ). 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. Clypeus 0.15 high. Chelicerae with three promarginal and four retromarginal teeth. Leg measurements: I 3.72 (1.08, 0.40, 0.86, 0.78, 0.60); II 3.61 (1.07, 0.38, 0.83, 0.76, 0.57); III 3.39 (0.98, 0.37, 0.71, 0.78, 0.55); IV 4.23 (1.19, 0.40, 1.01, 1.00, 0.63). Leg supination: femora I p1, II-III d1; patellae III-III d1; tibiae I-II p1 d1, III p1 d2 r1 v2, IV p1 d1 r1 v2; metatarsi III p1 d1 v2, IV p1 d2 r1 v2.

Coloration (Fig. 20E, F View Figure 20 ). 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 View Figure 14 , 18C View Figure 18 , 19C View Figure 19 ). Epigynal plate 1.3 × wider than long. Hoods 5 × depth than width. The posterior edge of copulatory openings touching, slightly curved. The width of thick copulatory ducts base 3 × 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.
