Order Peramelemorphia Author Wilson, Don E. Author Reeder, DeeAnn text 2005 The Johns Hopkins University Press Baltimore Mammal Species of the World: a Taxonomic and Geographic Reference (3 rd Edition), Volume 1 38 42 book chapter 0-8018-8221-4 10.5281/zenodo.7316519 Peramelidae Gray 1825 Peramelidae Gray 1825 , Ann. Philos., n. s., 10: 336 . Genera: 6 genera with 18 species in 3 subfamilies: Subfamily Peramelinae Gray 1825 Genus Isoodon Desmarest 1817 (3 species with 7 subspecies) Genus Perameles E. Geoffroy 1804 (4 species) Subfamily Peroryctinae Groves and Flannery 1990 Genus Peroryctes Thomas 1906 (2 species with 2 subspecies) Subfamily Echymiperinae McKenna and Bell 1997 Genus Echymipera Lesson 1842 (5 species with 6 subspecies) Genus Microperoryctes Stein 1932 (3 species with 3 subspecies) Genus Rhynchomeles Thomas 1920 (1 species) Discussion: Formerly considered to include the family Thylacomyidae ; see Vaughan (1978:39) and Groves and Flannery (1990) ; but also see Archer and Kirsch (1977) . Revised by Tate (1948 b ) . Divided by McKenna and Bell (1997) into two families: Peramelidae , with two subfamilies, Chaeropodinae (for Chaeropus and Macrotis ) and Peramelinae ; and Peroryctidae , with two subfamilies, Peroryctinae and Echymiperinae . Molecular data ( Westerman et al., 1999 , 2001) do not support the monophyly of Chaeropodinae in the sense of McKenna and Bell (1997) , show that Chaeropus is very distinct from other bandicoots, and do not support the monophyly of Peroryctidae .
