Miotopus is a monotypic genus of medium sized cave weta. The one species was originally placed in Pleioplectron by Hutton but he later moved it to the new genus Miotopus when additional specimens became available. Richards (1959) suggested it be returned to Pleioplectron, however unpublished genetic data do not support this treatment.
