Type material.

Holotype ♂ (IZCAS-Ar34050): China: Guangxi Zhuang Autonomous Region: Guilin City: Ludi Cave, 25°18.551'N, 110°15.822'E, elevation: 200 m, 6.XII.2015, Z. Chen and X. Zhang leg. Paratypes: 1♀ (IZCAS-Ar34051, zz391, KY778823), same cave as holotype, 25°18.505'N, 110°15.793'E, elevation: 200 m, 9.XII.2012, Z. Chen and Z. Zhao leg.; 1♂3♀♀ (IZCAS-Ar34052-Ar34055), same data as holotype; 2♀♀ (IZCAS-Ar34056, Ar34057), same cave as the holotype, 25°18.237'N, 110°16.218'E, elevation: 150 ± 3 m, 5-6.I.2018, Z. Chen leg.

Etymology.

The specific name is an adjective and refers to the type locality, Ludi Cave.

Diagnosis.

Males of Guilotes ludiensis sp. n. can be distinguished from G. xingpingensis sp. n. with the long patellar apophysis, wide lateral tibial apophysis (Figs 1C, 5C) and narrow conductor (Figs 1A, 5A) with swollen OC and large LC (Figure 1C). Differ from G. qingshitanensis sp. n. by the straight and short conductor with a LC and embolus beginning at 5 o’clock position (Figure 1B). Females can be distinguished from G. xingpingensis sp. n. by the epigynal teeth located in the middle of the atrial lateral margins (Figure 2A), copulatory ducts concave laterally and narrow fertilization ducts (Figure 2B). Differ from G. qingshitanensis sp. n. by the presence of epigynal teeth (Figure 2A) and sac-like of copulatory ducts (Figs 2B, 4B). Differ from G. yandongensis sp. n. by locations of epigynal teeth near the atrial lateral margins, atrium twice wider than long (Figure 2A), copulatory ducts ending horizontally and narrow fertilization ducts (Figure 2B).
