Three new cave-adapted chthoniid pseudoscorpions from four karst caves of Yunnan Province (China) are described, including detailed diagnosis and illustrations: Tyrannochthonius calvatus sp. nov. from an unnamed cave and Dongtianfu Cave (Fuyuan County), T. capito sp. nov. from Xianren Cave (Xichou County), and Lagynochthonius daidaiensis sp. nov. from Daidai Cave (Qiubei County). All three species are endemic to Yunnan. Tyrannochthonius calvatus sp. nov., lacking the carapaceal antero-median setae and having intercalary teeth on the movable chelal finger only, is a peculiar chthoniid species.
