Lundomys molitor (Winge 1887)

[Hesperomys] molitor Winge 1887, E Museo Lundii, Vol. 1, 3: 14.

Type Locality: Brazil, Minas Gerais State, cave chamber ("Lapa da Escrivania Nr. 5") near Lagoa Santa.

Vernacular Names: Lund's Amphibious Rat.

Synonyms: Lundomys magnus Hershkovitz 1955 .

Distribution: SE Brazil and Uruguay.

Conservation: IUCN – Lower Risk (lc) as Holochilus magnus .

Discussion: Species originally described based on fossils from Recent cave deposits in Minas Gerais, Brazil. Extant populations (described as Holochilus magnus Hershkovitz, 1955) apparently restricted to Rio Grande do Sul, Brazil, and Uruguay (González, 2000 b; Olrog and Lucero, 1981), but Pleistocene fossils known from EC Argentina (Pardiñas, 2000 b). Banded karyotypic comparisons with H. brasiliensis presented by Freitas et al. (1983 a, as H. magnus); synonymy of magnus demonstrated by Voss and Carleton (1993); González (2000 b) recognized magnus as a subspecies for Uruguayan populations.
