A new species of Coccoglypta Pilsbry, 1895 from China (Gastropoda, Camaenidae)

ABSTRACTA 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.urn:lsid:zoobank.org:pub:DC52A2B4-096C-4CC8-B986-29C789696F3C.KEYWORDS: Conchologyland snailsphylogenetic analysisSichuan Provincetaxonomy AcknowledgementsWe thank Mr Menghua Li (Sichuan Agricultural University) and Mr Jinsheng Mou (Sichuan Agricultural University) for assistance in collecting specimens and providing type specimens; Mr Zhengping Liu (Chengdu) for providing specimens of Coccoglypta pinchoniana and comments on the species identification; Dr Shijun Yang (Sichuan Agricultural University) for assistance in photo editing; Dr Frank Köhler (Australian Museum), Dr Barna Páll-Gergely (Plant Protection Institute, Hungary), Dr Sakboworn Tumpeesuwan (Mahasarakham University) and Dr Chung-Chi Hwang (National University of Kaohsiung) for their helpful comments on the manuscript.Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingThis work was supported by National Natural Science Foundation of China [grant number 31772412, 32360132].
