SPECIES Oryzomys russatus
| Author: | Wagner, 1848. | | Citation: | Abh. Math.-Phys. Classe K. B. Akad. Wiss. (Munchen), 5: 312. | | Common Name: | Russet Oryzomys | | Type Locality: | Brazil, São Paulo State, Ipanema. | | Distribution: | E Paraguay, SE Brazil (Bahia to Rio Grande do Sul), and NE Argentina (as per Massoia, 1975; Musser et al., 1998). | | Status: | IUCN – Lower Risk (lc) as O. intermedius and O. kelloggi. | | Comments: | The oldest available name for the form conventionally identified in the literature as intermedius, either used as a subspecies of O. capito (= O. megacephalus) (Cabrera, 1961) or as a distinct species (Gardner and Patton, 1976; Moojen, 1952; Musser and Carleton, 1993). Nomenclatural priority of russatus Wagner, lectotype designation, morphological definition, and distribution presented by Musser et al. (1998). A member of the O. nitidus group sensu Musser et al. (1998); most closely related to O. emmonsae and O. macconnelli based on evaluations of cytochrome b sequence data (Bonvicino and Martin Moreira, 2001; Patton et al., 2000). Extensive karyotypic variation advises that other species remain to be identified among the populations referred to russatus (see Silva et al., 2000). |
