Type material.

Holotype: ♂ (IZCAS-Ar44666), China, Guizhou: Dafang County, Sanhe Villiage, Yelaoda Cave, 27.1817°N, 105.4713°E, ca 1438 m, 03.V.2007, Y. Li and J. Liu leg. Paratypes: 1♂ 4♀ (IZCAS-Ar44667-Ar44671), same data as holotype.

Diagnosis.

Troglohnia dafang sp. nov. can be distinguished from T. qiubei sp. nov. by the tip of patellar apophysis pointed to 9:30 o’clock position (Fig. 17A) [vs 10:30 o’clock position (Fig. 17B)], ventral retrolateral tibial apophysis almost as long as dorsal retrolateral tibial apophysis (Fig. 10B) [vs 1:2 (Fig. 12B)], conductor stalk makes up 1/3 of total conductor length (Fig. 10A) [vs 1/2 (Fig. 12A)], process on tegulum absent (Fig. 10A) [vs present (arrowed in Fig. 12A)], copulatory openings touching each other (Fig. 11A) [vs facing each other (Fig. 13A)], diameter of primary spermathecae ~ 2 × diameters of secondary spermathecae (Fig. 11B) [vs 1.5 × (Fig. 13B)], distance between primary spermathecae and secondary spermathecae ~ 2 × diameters of secondary spermathecae (Fig. 11B) [vs 1 × (Fig. 13B)], secondary spermathecae separated by ~ 4 × diameters (Fig. 11B) [vs 1.5 × (Fig. 13B)], and fertilization ducts pointing to 9:00 o’clock position (Fig. 11B) [vs 7:30 o’clock position (Fig. 13B)]. Females of T. dafang sp. nov. can be distinguished from those of T. shidian sp. nov. by the ratio of diameter of secondary spermathecae to length of branched shorter copulatory ducts almost 1:2 (Fig. 11B) [vs 1:1 (Fig. 14B)], primary spermathecae elongate bean-shaped, separated by less than one diameter (Fig. 11B) [vs oval, separated by more than 2 × diameters (Fig. 14B)], diameter of primary spermathecae ~ 2 × diameters of secondary spermathecae (Fig. 11B) [vs 1.2 × (Fig. 14B)], distance between primary spermathecae and secondary spermathecae ~ 2 × diameters of secondary spermathecae (Fig. 11B) [vs 1 × (Fig. 14B)] and secondary spermathecae separated by ~ 4 × diameters (Fig. 11B) [vs 3 × (Fig. 14B)].
