Oryzomys galapagoensis (Waterhouse 1839)

[Oryzomys] galapagoensis (Waterhouse 1839), Zool. Voy. H. M. S. "Beagle", Mammalia: 66.

Type Locality: Ecuador, Galápagos Isls, Chatham Isl.

Vernacular Names: Galapagos Oryzomys.

Synonyms: Oryzomys bauri J. A. Allen 1892 .

Distribution: San Cristobal (= Chatham) and Sante Fe (= Barrington) Isls.

Conservation: IUCN – Extinct as O. g. galapagoensis, Vulnerable as G. g. bauri .

Discussion: Cabrera (1961) assigned bauri as a synonym of O. galapagoensis, an action more fully documented by Patton and Hafner (1983). Related to Oryzomys xanthaeolus complex on mainland South America (Gardner and Patton, 1976; Patton and Hafner, 1983). Extirpated from San Cristobal Isl ( galapagoensis proper) but populations (O. g. bauri) still inhabit Sante Fe Isl (see Dowler et al., 2000; Patton and Hafner, 1983).
