Type material.

Holotype China • ♂ ( SYNU -1172 ); Anhui, Xuancheng City, Jingde County, Tu’er Mountain ; 30°18'23"N, 118°32'15"E, 240 m; 7.I.2022; W. Cheng, H. Fu & K. Yang leg. Paratype: China • 4 ♂ 1 ♀ ( SYNU -1173 –1177), same data as holotype .

Etymology.

The specific name refers to the type locality and is a noun in apposition.

Diagnosis.

This new species is similar to Leptonetela microdonta ( Wang and Li 2011: figs 28–31) in the long setae on palpal tibia, but can be distinguished by the chelicerae with seven promarginal teeth (Fig. 13 B ) vs. eight, palpal tibia with four long setae retrolaterally, the basal two thick (Fig. 7 D ) vs. six long setae, with the basal one thinner and the distal three thick, the prolateral sclerite spine-like (Fig. 8 D ) vs. fork-shaped, with five teeth distally and the abdomen with four dark chevron-shaped stripes (Figs 7 A , 9 A ) vs. lacking.

Description.

Male (holotype). Habitus as in Fig. 7 A, B . Total length 1.25. Carapace 0.61 long, 0.59 wide. Abdomen 0.89 long, 0.73 wide. Eye sizes and interdistances: ALE 0.08, PLE 0.08, PME 0.07; ALE – PME 0.08, PLE – PLE 0.08, PLE – PME 0.03; AER 0.14, PER 0.17. Carapace light yellow. Median groove, cervical grooves and radial furrows distinct. Chelicerae with seven large promarginal and four small retromarginal teeth, with stridulatory file on the lateral margin. Labium rectangular; endites with serrula anterolaterally; sternum brown, shield shaped, smooth. Abdomen whitish, ovoid, with four dark chevron-shaped stripes. Leg measurements: I 2.66 (0.72, 0.17, 0.73, 0.57, 0.47); II 2.20 (0.62, 0.17, 0.55, 0.46, 0.40); III 1.97 (0.58, 0.18, 0.46, 0.46, 0.29); IV 2.45 (0.72, 0.17, 0.62, 0.54, 0.40). Palp (Figs 7 C, D , 8 A – E ): femur without long setae retrolaterally; tibia with four long setae retrolaterally, the basal two thick; cymbium constricted medially, attached to a large earlobe-shaped process retrolaterally; tip of bulb with a short spine-like prolateral sclerite and leaf-shaped median apophysis.

Female (paratype). Similar to male in general features. Habitus as in Fig. 9 A, B . Total length 1.36. Carapace 0.64 long, 0.58 wide. Abdomen 0.96 long, 0.80 wide. Eye sizes and interdistances: ALE 0.08, PLE 0.07, PME 0.07; ALE – PME 0.12, PLE – PLE 0.08, PLE – PME 0.02; AER 0.14, PER 0.17. Leg measurements: I - (0.73, 0.20, 0.67, 0.56, -); II 2.19 (0.62, 0.20, 0.52, 0.45, 0.40); III 1.97 (0.58, 0.18, 0.44, 0.45, 0.32); IV - (0.73, 0.21, 0.62, -, -). Internal genitalia (Fig. 9 C, D ) with sub-trapezoidal atrium, slightly swollen spermathecae, and convoluted spermathecal stalk including six coils.
