Calomys tener Winge 1887

Calomys tener Winge 1887 , E Museo Lundii, Vol. 1, 3: 15.

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

Vernacular Names: Delicate Laucha.

Distribution: Atlantic Forest region and habitats bordering the Cerrado, SE Brazil (S Goiás, Minas Gerais, São Paulo), and in NE Argentina (Misiones Prov., Massoia, 1988) and E Bolivia ( Anderson, 1997); range limits need refinement.

Conservation: IUCN – Lower Risk (lc).

Discussion: Arranged as a subspecies of C. laucha by Hershkovitz (1962), but others have retained tener and C. laucha as distinct species (Cabrera, 1961; Mares et al., 1989 a; Moojen, 1952; Olds, 1988). Karyotypic identity (2n = 66, FN = 66) clarified by Bonvicino and Almeida (2000), who expanded upon its morphological and ecological separation from C. expulsus . Anderson (1997) considered identification of the Bolivian specimens as tentative and advised further review of series presently allocated to C. callosus .
