Types. Holotype ♀, CHINA, Yunnan, Tengchong County, Bawan Township, Sanchahe, Luoshuidong area, 24.94755°N, 98.75564°E, alt. 2300m, night collecting in broadleaf forest, 3 June 2005, Heng-mei Yan, Ke-ji Guo and Hong-bin Liang leg. (GKJ039).

Etymology. This epithet derives from the type locality.

Diagnosis. This new species resembles Auricula triangulara sp. nov. in having the globular spermathecae present on lateral side of dorsal plate (Fig. 22A–C; Fig. 27A–C), but can be distinguished by posterior margin of the dorsal plate wave-shaped, protruding distinctly beyond the epigastric groove in A. sanchaheensis sp. nov. (Fig. 22A), whereas straight, and not distinctly beyond the epigastric groove in A. triangulara sp. nov. (Fig. 27A). Copulatory duct of the new species two times longer than that of A. triangulara sp. nov. (Fig. 22C; Fig. 27C).

Description. Female (holotype, Fig. 23A, B): Total length: 2.68. Carapace 1.29 long, 0.99 wide, brown, mid dorsally slightly elevated; fovea, cervical and radial grooves distinct. Clypeus 0.27 high. Sternum longer than wide, brown, sparsely covered with microsetae. Labium wider than longer. Maxillae long, distal end broad with scopulae. Chelicerae with four promarginal and five retromarginal teeth. Eye region narrow, AER straight, PER procurved slightly wider than AER. Eye sizes and interdistances:AME 0.06, ALE 0.10, PME 0.07, PLE 0.08, AME–AME 0.03, PME–PME 0.08, AME–ALE, 0.03, PME–PLE 0.07, AME–PME 0.07, ALE–ALE 0.36, PLE– PLE 0.42, ALE–PLE contiguous. Legs lost. Abdomen 1.39 long, 0.89 wide, oval, greenish-grey, dorsally with two longitudinal black bands; ventral side dusky gray.

Epigyne (Fig. 22A–C): wider than long, sclerotized; ventral plate connected with dorsal plate by septum to form shallow atrium with copulatory openings; dorsal plate sclerotized, with round wave-like margin protruding distinctly beyond the epigastric groove, mid ventrally with a shallow depression; copulatory openings narrow, present at the base of septum posteriorly. Vulva with long copulatory ducts, forming pairs of round broad loops anteriorly, extending above the spermathecae; spermathecae globular, on lateral side of dorsal plate, pointing away from each other.

Male. Unknown.

Distribution. Known only from the type locality (Fig. 29).

Remarks. Auricula sanchaheensis sp. nov. has been described with the only holotype female that was dried out. But the epigyne is undamaged, so it is used to describe this species.
