SPECIES Necromys lasiurus

Author:Lund, 1840.
Citation:K. Dansk. Vid. Selsk. Naturv. Math. Afhandl., 8: 50.
Common Name:Hairy-tailed Akodont
Type Locality:Brazil, Minas Gerais State, Rio das Velhas, Lagoa Santa.
Distribution:C Brazil south of the Amazon River, extreme SE Perú (as per Pacheco et al., 1995), and perhaps NE Argentina (see Galliari et al., 1996); limits uncertain.
Status:IUCN – Lower Risk (lc) as Bolomys lasiurus.
Comments:Revised as part of Zygodontomys (Hershkovitz, 1962); inclusion of lasiurus within Bolomys (or Akodon), not Zygodontomys, supported by karyological and morphological information (see Gardner and Patton, 1976; Maia and Langguth, 1981; Voss and Linzey, 1981). Geographic variation assessed, as Bolomys lasiurus, by Macêdo and Mares (1987), who retained only fuscinus and lasiurus as subspecies. The validity of listed synonyms very much needs confirmation: e.g., the taxon arviculoides is considered a species by some (Cabrera, 1961; Gyldenstolpe, 1932; Ximénez & Langguth, 1970), or reallocated to lasiurus by others (Macêdo and Mares, 1987; Reig, 1978, 1987), while Galliari and Pardiñas (2000) passingly mention it as another species related to N. obscurus. Also see following account of N. lenguarum, included by some (e.g., Macêdo and Mares, 1987) as another junior synonym; morphological discrimination and distributional limits of the two forms require refinement.
