Satrapanus is a monotypic genus of pseudoscorpions in the Chernetidae family. It is endemic to Australia's Lord Howe Island in the Tasman Sea. It was described in 2007 by Australian arachnologists Mark Harvey and Erich Volschenk. The generic epithet comes from the Latin satrapa ('provincial governor') with reference to the pseudoscorpion being the only known species of the genus on the island.

Distribution and habitat The species is known only from Lord Howe Island, where it inhabits plant litter and other ground habitats.
