First record of the subfamily Geracinae Brindle, 1971 and genus Pseudovostox Borelli, 1926 (Dermaptera, Spongiphoridae) in China, with a description of a new species.

The subfamily Geracinae Brindle, 1971, and the genus Pseudovostox Borelli, 1926, are recorded for the first time from China. These new records were confirmed by collections from Guiyang City in Guizhou Province, located in southwestern China. Pseudovostox guizhouensis sp. nov. is described and illustrated based on specimens from this region. Although the new species closely resembles the Oriental species Pseudovostox fasciatus (de Bormans, 1894), it can be distinguished by a combination of unique morphological characters. An updated key and distribution map for Pseudovostox species are provided to aid future research and species identification.
