404D879CFF8AFF82FDE4CB450B02FCBE.taxon	biology_ecology	Habitat The cave was about 5 – 20 m high, 15 – 80 m wide, and its length was unknown. The new species were collected from under damp, shaded gravel about 80 m from the cave entrance. At the same time, some species of spiders, millipedes and neobisiid pseudoscorpions were also collected.	en	Yun-Chun LI (2023): Three new species of pseudoscorpions (Arachnida: Pseudoscorpiones: Pseudotyrannochthoniidae) from caves in Yunnan and Guizhou Provinces, China.
