Order Rodentia - Family Nesomyidae 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 2 930 955 book chapter 0-8018-8221-4 10.5281/zenodo.7316535 Steatomys parvus Rhoads 1896 Steatomys parvus Rhoads 1896 , Proc. Acad. Nat. Sci. Philadelphia: 529 . Type Locality: Ethiopia , northern shore Lake Turkana, Rusia (see Yalden et al., 1996 ). Vernacular Names: Tiny African Fat Mouse . Synonyms: Steatomys aquilo Thomas and Hinton 1923 ; Steatomys athi Heller 1910 ; Steatomys kalaharicus Roberts 1932 ; Steatomys loveridgei Thomas 1919 ; Steatomys minutus Thomas and Wroughton 1905 ; Steatomys muanzae Kershaw 1923 ; Steatomys swalius Thomas 1926 ; Steatomys thomasi Setzer 1956 ; Steatomys umbratus Thomas 1926 . Distribution: East and Southern Africa—S and EC Sudan ( holotypes of aquilo and thomasi ; USNM specimens), S Ethiopia , and Somalia ; south through Kenya ( Hollister, 1919 ; specimens in AMNH ), Uganda ( Delany, 1975 ; AMNH 119143), and Tanzania ( Swynnerton and Hayman, 1951 ); to SW Angola ( Coetzee, 1977 a ; Crawford-Cabral, 1998 ; AMNH 81949), NE Namibia , NW Botswana ( Smithers, 1971 ), W Zambia ( Ansell, 1978 ), and W Zimbabwe ( Smithers and Wilson, 1979 ). Conservation: IUCN – Lower Risk (lc). Discussion: Distribution and conservation status discussed as a savanna woodland species by Mugo et al. (1995) . The single Ethiopian record was first listed as S. pratensis ( Yalden et al., 1976 ) and later reidentified as S. parvus ( Yalden et al., 1996 ) . Coetzee (1977 a ) omitted thomasi from his review; Setzer’s (1956) large type series matches the range of variation in what is now regarded as S. parvus . Coetzee (1977 a ) included the holotype and only specimen of aquilo ( EC Sudan , Jebel Marra) in S. parvus , although Thomas and Hinton (1923 a ) believed it to be related to West African S. cuppedius . Southern African records reviewed and mapped by de Graaff (1997 gg ), who included an isolate in KwaZulu-Natal, but Taylor (1998) reallocated those specimens to S. krebsii . Steatomys parvus has not been found south of NE Namibia and NW Botswana , nor have we located any samples between S Sudan and the eastern range limits of West African S. cuppedius (see account).
