Abstract Two Microcreagris species belonging to the family Neobisiidae are described from China: Microcreagris gigas Balzan, 1892 from Fanjing Mountain in Guizhou Province, and Microcreagris xikangensis sp. nov. from the Xikang-Tibet Plateau in Sichuan Province. Detailed diagnosis, descriptions and illustrations of the two species are presented. Key words: taxonomy, pseudoscorpion, Microcreagris, new species, China. Introduction The pseudoscorpion genus Microcreagris was established by Balzan (1892) with the Chinese type species M. gigas Balzan, 1892. Many species were later described and placed in this genus, but Mahnert (1974, 1979) and Ćurčić (2001) emended the diagnosis of Microcreagris and presented modern, detailed redescriptions of M. gigas based on the type specimens. Most of these species have been subsequently transferred to different genera, and 22 species were recorded in Microcreagris by Harvey (2013). However, only two species can be unequivocally placed in the genus Microcreagris: M. gigas from China and M. herculea Beier, 1959 from Afghanistan, according to Ćurčić (2001). During examination of pseudoscorpion specimens collected by sieving leaf litter from the Xikang- Tibet Plateau in Sichuan Province, China, we found a third species which definitely belongs to the genus Microcreagris: M.
