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) [vs strongly curved and wider than dorsal retrolateral tibial apophysis (Fig. 15B)], embolic tooth terminal flat (Fig. 12A) [vs terminal finger-shaped (Fig. 15A)], process on anterior 1/3 of tegulum (arrowed in Fig. 12A) [vs on anterior 3/5 (arrowed in Fig. 15A)] and female can be distinguished by the diameter of secondary spermathecae less than diameter of primary spermathecae (Fig. 13B) [vs almost same diameter (Fig. 16B)], distance between primary spermathecae and secondary spermathecae more than half of diameter of secondary spermathecae (Fig. 13B) [vs less than half of diameter (Fig. 16B)], secondary spermathecae separated by ~ 1.5 × diameters (Fig. 13B) [vs 1 × (Fig. 16B)] and fertilization ducts pointing to 7:30 o’clock position (Fig. 13B) [vs 9:00 o’clock position (Fig. 16B)]. 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) [vs 9:30 o’clock position (Fig. 17A)], ventral retrolateral tibial apophysis shorter than dorsal retrolateral tibial apophysis (Fig. 12B) [vs almost as long as dorsal retrolateral tibial apophysis (Fig. 10B)], conductor stalk makes up 1/2 of total conductor length (Fig. 12A) [vs 1/3 (Fig. 10A)], process on tegulum present (Fig. 12A) [vs absent (Fig. 10A)], copulatory openings facing each other (Fig. 13A) [vs touching each other (Fig. 11A)], diameter of primary spermathecae ~ 1.5 × diameters of secondary spermathecae (Fig. 13B) [vs 2 × (Fig. 11B)], distance between primary spermathecae and secondary spermathecae ~ 1 × diameter of secondary spermathecae (Fig. 13B) [vs 2 × (Fig. 11B)], secondary spermathecae separated by ~ 1.5 × diameters (Fig. 13B) [vs 4 × (Fig. 11B)], and fertilization ducts pointing to 7:30 o’clock position (Fig. 13B) [vs 9:00 o’clock position (Fig. 11B)].
