Abstract

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