Bibimys labiosus (Winge, 1887) . E Museo Lundii, 1 (3):25.

TYPE LOCALITY: Brazil, Minas Gerais, Pleistocene cave deposits near Lagoa Santa .

DISTRIBUTION: Minas Gerais, Brazil.

COMMENTS: Described as a species of Scapteromys, referred to Akodon by Hershkovitz (1966c), and reidentified as a species of Bibimys by Massoia (1980a). As with other sigmodontine species described by Winge (1887) from the Lagoa Santa caves, the relationship of B. labiosus to species named later warrants critical investigation (see Voss and Myers, 1991).
