SPECIES Oryzomys seuanezi
| Author: | Weksler, Geise, and Cerqueira, 1999. | | Citation: | Zool. Jour. Linnean Soc., 125: 454. | | Common Name: | Seuánez’s Oryzomys | | Type Locality: | Brazil, Rio de Janeiro State, Casimiro de Abreu Municipality, Fazenda União, 50 m; 22º25′S, 42º02′W. | | Distribution: | Atlantic Forest, SE Brazil. | | Comments: | Morphometric and karyological comparisons with other Brazilian members of the O. megacephalus complex provided by Weksler et al. (1999); a sister species to O. oniscus (or O. laticeps sensu Musser et al., 1998). The level of differentiation of this species from Lund’s (1840) laticeps, identified by Musser et al. (1998) as the senior synonym for the large megacephalus like form of the Atlantic Forest region, deserves further examination. |
