SPECIES Necromys lactens

Author:Thomas, 1918.
Citation:Ann. Mag. Nat. Hist., ser. 9, 1: 188.
Common Name:White-chinned Akodont
Type Locality:Argentina, Jujuy Prov., León, about 1500 m.
Distribution:E Andean highlands, about 2100-4000 m, of SC Bolivia (see Anderson and Olds, 1989) and NW Argentina (Jujuy, Salta, Catamarca, and Tucumán Provs.; see Ortiz et al., 2000a).
Status:IUCN – Lower Risk (lc) as Bolomys lactens.
Comments:Galliari and Pardiñas (1995) reidentified leucolimnaeus, previously considered a subspecies of lactens (Cabrera, 1961; Gyldenstolpe, 1932), as a species of Akodon and questioned (2000:226) the synonymy of negrito and orbus, as attributed by Cabrera (1961), as "dubious." Capllonch et al. (1997) had resurrected N. orbus based on a single specimen from Tucumán Prov., but Pardiñas and Galliari (1998b) considered the action to be inadequately documented.
