Perizoma is a genus in the geometer moth family (Geometridae). It is the type genus of tribe Perizomini in subfamily Larentiinae. The tribe is considered monotypic by those who include the genera Gagitodes, Martania and Mesotype in Perizoma. Some other less closely related species formerly placed here are now elsewhere in the Larentiinae, e.g. in Entephria of the tribe Larentiini.
