Diagnosis.

Pinelema pacchanensis resembles P. daguaiwan sp. nov. but can be distinguished by the following: the ventrally concave part of the bulb is weaker (Fig. 3B, and cf. Zhao et al. 2018a: fig. 11A, B) (vs. stronger), the larger length ratio of the embolus/bulb (0.71, Fig. 3B, and cf. Zhao et al. 2018a: fig. 11A, B) (vs. 0.48), and the triangular embolus (cf. Zhao et al. 2018a: fig. 11 A-D) (vs. tube-shaped); the diameter ratio of the receptacle tip/neck is 2.0 (cf. Zhao et al. 2018a: fig. 12C) (vs. 7.0).
