Type material. Holotype ♂: CHINA, Guizhou Province, Rongjiang County, Shuiwei Township, Yueliang Mountain , Shanglali , 25.6535°N, 108.24666667°E, 902 m, 22.X.2014, T. Lu & H.M. Chen leg (SWUC-T-AG-54-01).

Etymology. The specific epithet refers to the type locality; adjective.

Diagnosis. The male of Tonsilla yueliangensis can be distinguished from all other congeners by the following characters: patellar apophysis originating from the dorso-lateral margin of patella; conductor apex robust, round, grooved and curved anticlockwise; conductor’s dorsal apophysis slightly curved with bifurcated tip; median apophysis inverted J-shaped.

Description. Male (holotype, Fig. 9M ). Total length 14.95. Carapace 8.07 long, 5.10 wide; opisthosoma 6.97 long, 4.54 wide. Eye sizes and interdistances: AME 0.27, ALE 0.34, PME 0.30, PLE 0.29; AME–AME 0.14, AME– ALE 0.11, PME–PME 0.15, PME–PLE 0.35, ALE–PLE 0.11. MOA 0.80 long, front width 0.63, back width 0.76. Clypeus height 0.18. Leg measurements: I 24.19 (6.26, 7.82, 5.98, 4.13); II 21.76 (5.92, 6.74, 5.45, 3.65); III 19.17 (5.28, 5.66, 5.12, 3.11); IV 25.08 (6.11, 7.94, 7.41, 3.62). Spination of legs: femur I-II 220, III 240, IV 210; patella I-II 000, III-IV 010; tibia I-II 026, III-IV 046; metatarsus I-II 046, III-IV 066.

Palp ( Fig. 8A–C ). Patella almost equal to the length of patellar apophysis; patellar apophysis long, curved, and originating from the dorso-lateral margin of patella. Retrolateral and lateral tibial apophysis distinct and with blunt end. Cymbium, approximately 3 times longer than wide; cymbial furrow extensively sclerotized, about half of the cymbial length. Median apophysis inverted J-shaped. Conductor apex robust, round, grooved and curved anticlockwise. Conductor’s dorsal apophysis slightly curved with bifurcated tip. Conductor lamella distinct. Embolus filiform, originating at the 6 o’clock position.

Female. Unknown.

Distribution. China (Guizhou) ( Fig. 10 ).
