Type material.

Holotype: ♂ (IZCAS-Ar44672), China, Yunnan: Wenshan Zhuang and Miao Autonomous Pref., Qiubei County, Shuanglongying Town, Puzhehei Villiage, Dongjiadashi Cave, 24.1422°N, 104.0990°E, ca 1455 m, 19.VIII.2010, Z. Yao, X. Wang and C. Wu leg. Paratypes: 5♂ 5♀ (IZCAS-Ar44673-Ar44682), same data as holotype.

Diagnosis.

Troglohnia qiubei sp. nov. can be distinguished from T. wuding sp. nov. by the male ventral retrolateral tibial apophysis almost straight and as wide as dorsal retrolateral tibial apophysis (Fig. 12B View Figure 12 ) [vs strongly curved and wider than dorsal retrolateral tibial apophysis (Fig. 15B View Figure 15 )], embolic tooth terminal flat (Fig. 12A View Figure 12 ) [vs terminal finger-shaped (Fig. 15A View Figure 15 )], process on anterior 1/3 of tegulum (arrowed in Fig. 12A View Figure 12 ) [vs on anterior 3/5 (arrowed in Fig. 15A View Figure 15 )] and female can be distinguished by the diameter of secondary spermathecae less than diameter of primary spermathecae (Fig. 13B View Figure 13 ) [vs almost same diameter (Fig. 16B View Figure 16 )], distance between primary spermathecae and secondary spermathecae more than half of diameter of secondary spermathecae (Fig. 13B View Figure 13 ) [vs less than half of diameter (Fig. 16B View Figure 16 )], secondary spermathecae separated by ~ 1.5 × diameters (Fig. 13B View Figure 13 ) [vs 1 × (Fig. 16B View Figure 16 )] and fertilization ducts pointing to 7:30 o’clock position (Fig. 13B View Figure 13 ) [vs 9:00 o’clock position (Fig. 16B View Figure 16 )]. T. qiubei sp. nov. also resembles T. dafang sp. nov., but can be distinguished by the tip of patellar apophysis pointed to 10:30 o’clock position (Fig. 17B View Figure 17 ) [vs 9:30 o’clock position (Fig. 17A View Figure 17 )], ventral retrolateral tibial apophysis shorter than dorsal retrolateral tibial apophysis (Fig. 12B View Figure 12 ) [vs almost as long as dorsal retrolateral tibial apophysis (Fig. 10B View Figure 10 )], conductor stalk makes up 1/2 of total conductor length (Fig. 12A View Figure 12 ) [vs 1/3 (Fig. 10A View Figure 10 )], process on tegulum present (Fig. 12A View Figure 12 ) [vs absent (Fig. 10A View Figure 10 )], copulatory openings facing each other (Fig. 13A View Figure 13 ) [vs touching each other (Fig. 11A View Figure 11 )], diameter of primary spermathecae ~ 1.5 × diameters of secondary spermathecae (Fig. 13B View Figure 13 ) [vs 2 × (Fig. 11B View Figure 11 )], distance between primary spermathecae and secondary spermathecae ~ 1 × diameter of secondary spermathecae (Fig. 13B View Figure 13 ) [vs 2 × (Fig. 11B View Figure 11 )], secondary spermathecae separated by ~ 1.5 × diameters (Fig. 13B View Figure 13 ) [vs 4 × (Fig. 11B View Figure 11 )], and fertilization ducts pointing to 7:30 o’clock position (Fig. 13B View Figure 13 ) [vs 9:00 o’clock position (Fig. 11B View Figure 11 )].
