Type material.
Holotype: ♂ (IZCAS), China, Guizhou Province, Qianxinan Buyi and Miao Autonomous Prefecture, Wangmo County, Sanglang Town, Xinghe Village, Daguaiwan Cave. 25.2706N, 106.4328E, elevation ca. 886 m, 29.XII.2010, Z. Zha and Z. Chen leg. Paratypes: 1♂ and 5♀ (IZCAS), same data as holotype.
Etymology.
The species name refers to the type locality; noun in apposition.
Diagnosis.
Pinelema daguaiwan sp. nov. resembles P. pacchanensis by the bulb being concave ventrally but can be distinguished by the following: the bulb is more deeply concave (arrow in Fig. 4C, D View Figure 4 ) (vs. weaker), the smaller length ratio of the embolus/bulb (0.48, Figs 3B View Figure 3 , 4C, D View Figure 4 ) (vs. 0.71), the triangular embolus (Figs 3B View Figure 3 , 4C, D View Figure 4 ) (vs. tube-shaped); the diameter ratio of the receptacle tip/neck is 7.0 (Fig. 5A View Figure 5 ) (vs. 2.0).
