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) (vs. weaker), the smaller length ratio of the embolus/bulb (0.48, Figs 3B, 4C, D) (vs. 0.71), the triangular embolus (Figs 3B, 4C, D) (vs. tube-shaped); the diameter ratio of the receptacle tip/neck is 7.0 (Fig. 5A) (vs. 2.0).
