Euneomys fossor Thomas 1899

Euneomys fossor Thomas 1899, Ann. Mag. Nat. Hist., ser. 7, 4: 280.

Type Locality: Argentina, "Prov. Salta." .

Vernacular Names: Burrowing Euneomys.

Distribution: Known only from the type locality, which is questionable as Euneomys is otherwise unrecorded this far north in Argentina (see Mares et al., 1989 b).

Discussion: Holotype of Reithrodon fossor Thomas, 1899, type species of Chelemyscus Thomas, 1925, is a composite, the designated type skull referable to Euneomys (Osgood, 1943:164; Pearson, 1984:231). Status is doubtful —"the name Chelemyscus fossor should be attached to an appropriate species of Euneomys by some future revisor" (Pearson, 1984:231). Galliari et al. (1996) considered it a nomen dubium.
