"The holotype of the Colombian Oryzomys villosus is shown to be a composite: the skull is an example of Oryzomys albigularis, the skin from an Oryzomys talamancae. The latter, usually included within the species definition of O. capito, appears to be distinct biological species with a geographic range extending from eastern Costa Rica through Panama to the valleys and lower Andean slopes of Ecuador, Colombia, and western Venezuela; its habitat is evergreen and deciduous tropical forest from near sea level up to about 5000 ft. Identifying villosus and talamancae is part of systematically revising the genus Oryzomys, a task that can now be accomplished by study of the many specimens now housed in collections of natural history museums"--P.
