A new camaenid land snail species: Coccoglypta limenghuai Chen, Xie, Dai & Wu, n. sp. is described from Yaan City, Sichuan Province, China based on morphology and phylogenetic analysis. Coccoglypta ellenstrongae Thach & Huber, 2021 is treated as a junior synonym of Acusta toyenmongaiensis Rolle, 1911. Coccoglypta limenghuai is morphologically different from the congeneric species by the depressed conical shell, strongly keeled and almost flat whorls and a shallow groove-like depression below the keel of the body whorl. The habitat of the species has been severely damaged and it survives only within an area of a few hundred square metres. Further attention and protection should be given to it in the future. .
