Types. Holotype ♀, China, Yunnan, Tengchong County, Qushui Township, Gaoshidong Village , 25.39859°N, 98.30531°E, alt. 2583m, 27 May 2006, Xin-ping Wang and Peng Hu leg. (Wang060527–1).

Etymology. This epithet derives from the type locality.

Diagnosis. The new species resembles Linyphia triangularoides Schenkel, 1936 ( Tanasevitch, 1989, fig. 226) in having the similar scape, but can be distinguished by the spiral folds with two and half turns in L. gaoshidongensis sp. nov. ( Fig. 175B, C ), whereas with three and half turns in L. triangularoides ( Tanasevitch, 1989, fig. 226).

Description. Female (holotype, Fig. 176A, B ): Total length: 4.77. Carapace 1.67 long, 1.20 wide, yellow– brown; fovea, cervical and radial grooves distinct. Clypeus 0.23 high. Sternum longer than wide, brown. Labium wider than long. Maxillae long, distal end broad with scopulae. Chelicerae with two promarginal and three retromarginal teeth. AER recurved, PER procurved, slightly wider. Eye sizes and interdistances: AME 0.10, ALE 0.12, PME 0.08, PLE 0.09, AME–AME 0.05, PME–PME 0.12, AME–ALE, 0.10, PME–PLE 0.13, AME–PME 0.16, ALE–ALE 0.59, PLE–PLE 0.64, ALE–PLE contiguous. Length of legs: I 9.89 (2.66, 3.04, 2.86, 1.33), II 7.24 (2.13, 2.06, 2.04, 1.01), III 5.58 (1.97, 1.37, 1.49, 0.75), IV 6 (1.90, 1.70, 1.42, 0.98). Leg formula I-II-IV-III. Tm I 0.69. Tibial spine formula: 2-2-2-2. Abdomen 2.78 long, 1.77 wide, oval, gray, middorsally with a large distinct longitudinal black pattern with serrated margins, lateral sides with white patches; ventral side light brown, median area with a wide langitudinal gray band, lateral area with two inclined dark striae.
