Kunsia Hershkovitz, 1966 . Z. Säugetierk., 31 (2):112.

TYPE SPECIES: Mus tomentosus Lichtenstein, 1830 .

COMMENTS: Species formerly included in Scapteromys until set apart in Kunsia by Hershkovitz (1966c), who arranged both genera in the scapteromyine "group," which he viewed as closely related to oxymycterines. Formal tribal segregation of the two genera affirmed by Reig (1980). Karyology summarized by Gardner and Patton (1976).
