Achalinus yangdatongi Hou, Wang, Guo, Chen, Yuan & Che, 2021 was described based on single specimen. After morphological examination of recently collected specimens from the type locality and close region, several specimens (3 females and 1 male) were identified as this species. Genetic distances (p-distance) calculated from a fragment of the mtDNA gene, cytochrome c oxidase subunit I (COI) were less than 1.8% between the newly collected specimens and the type specimen. Achalinus yangdatongi is redescribed and several of its diagnostics are revised accordingly: dorsal body scales 23 rows throughout; ventrals 155–171; subcaudals 59–76, unpaired; maxillary teeth 24–26.
