Zhang and Z. Chen leg. Paratypes: 1♀ (IZCAS-Ar34059, zz892, KY778825), same cave as holotype, 25°31.137'N, 110°14.908'E, elevation: 173 m, 21.XII.2013, H. Zhao leg.; 1♂2♀♀ (IZCAS-Ar34060-Ar34062), same data as holotype; 2♂♂2♀♀ (IZCAS-Ar34063-Ar34066), same cave as holotype, 25°31.607'N, 110°14.967'E, elevation: 201 ± 4 m, 3.I.2018, Z. Chen leg.

Etymology.

The specific name is an adjective and refers to the type locality, Qingshitan Town.

Diagnosis.

Males of Guilotes qingshitanensis sp. n. differ from G. ludiensis sp. n. and G. xingpingensis sp. n. by long and bent conductor and OC (Figure 3 A–B), LC with saw-shaped margin (Figure 3C), embolus beginning at 4 o’clock position (Figure 3B), small median apophysis with needle-shaped top and spoon-shaped end (Figure 3 B–C). Females differ from G. ludiensis sp. n., G. xingpingensis sp. n. and G. yandongensis sp. n. by the absence of epigynal teeth (Figure 4A) and spiral copulatory ducts (Figure 4B).
