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).

Description.

Male (holotype, IZCAS-Ar34050): Total length 5.94. Carapace 3.56 long, 2.77 wide. Abdomen 2.38 long, 1.78 wide. Eye diameters and interdistances: AME: 0.08, ALE: 0.16, PME: 0.15, PLE: 0.15; AME–AME: 0.04, AME–ALE: 0.03, AME–PME: 0.10, ALE–PLE: 0.02, PME–PME: 0.05, PME–PLE: 0.05. Leg measurements: I: 11.22 (3.96, 3.26, 2.60, 1.40); II: 10.51 (3.61, 3.36, 2.18, 1.36); III: 10.01 (3.39, 3.05, 2.38, 1.19); IV: 12.41 (4.17, 3.68, 3.17, 1.39). Chelicerae with five promarginal and five retromarginal teeth. Palp: patellar apophysis finger-shaped, its length shorter than width of patella (Figure 1C); RTA narrow, pointed tip (Figure 1C); LTA short, approximately 1/2 length of RTA (Figure 1C); cymbial furrow long, subequal to 2/3 length of cymbium (Figure 1C); embolus filiform, beginning at 5 o’clock position (Figure 1B); conductor short, horizontally directed (Figure 1 A–B); OC located at the base of the conductor (Figure 1A) and LC located behind the outgrowth (Figure 1C); median apophysis small, spoon-like (Figure 1 B–C).

Female (one of the paratypes, IZCAS-Ar34053): Total length 5.54. Carapace 2.57 long, 1.44 wide. Abdomen 2.97 long, 2.08 wide. Eye diameters and interdistances: AME: 0.05, ALE: 0.12, PME: 0.10, PLE: 0.11; AME–AME: 0.06, AME–ALE: 0.03, AME–PME: 0.08, ALE–PLE: 0.05, PME–PME: 0.08, PME–PLE: 0.07. Leg measurements: I: 7.08 (2.59, 2.21, 1.42, 0.86); II: 6.13 (2.06, 1.80, 1.46, 0.81); III: 5.52 (2.01, 1.61, 1.21, 0.69); IV: 7.66 (2.79, 2.41, 1.61, 0.85). Chelicerae with six promarginal and five or six retromarginal teeth. Epigyne: teeth short, less than 1/2 atrial length, located near the atrial lateral margins (Figure 2A); atrium small, occupying 1/7 epigynal plate (Figure 2A); copulatory ducts broad, occupying 3/4 epigynal plate (Figure 2B); spermathecae cylindrical, elongated and posterior, stay away from each other (Figure 2B); spermathecal heads long, stretched to the back (Figure 2B).

Variation.

Total length: males 5.94-6.53 (n = 2); females 5.54-7.13 (n = 6).

Distribution.

Males and females of this species were collected from Ludi Cave, Guilin City, Guangxi Zhuang Autonomous Region, China (Figure 8).
