Necromys lasiurus (Lund 1840)

[Necromys] lasiurus (Lund 1840) , K. Dansk. Vid. Selsk. Naturv. Math. Afhandl., 8: 50.

Type Locality: Brazil, Minas Gerais State, Rio das Velhas, Lagoa Santa.

Vernacular Names: Hairy-tailed Akodont.

Synonyms: Necromys arviculoides (Wagner 1842) ; Necromys brachyurus (Wagner 1845) ; Necromys fuscinus (Thomas 1897) ; Necromys lasiotus (Lund 1838) ; Necromys orobinus (Wagner 1842) ; Necromys pixuna (Moojen 1943) ; Necromys renggeri (Pictet 1844) .

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.

Conservation: IUCN – Lower Risk (lc) as Bolomys lasiurus .

Discussion: 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.
