SPECIES Oligoryzomys fulvescens

Author:Saussure, 1860.
Citation:Revue Mag. Zool. Paris, ser. 2, 12: 102.
Common Name:Fulvous Colilargo
Type Locality:México, Veracruz State, Orizaba (as restricted by Merriam, 1901a:295).
Distribution:W and E versants of S México, through Central America, to Ecuador, N and C Venezuela, Guianas, and northernmost Brazil in South America.
Status:IUCN – Lower Risk (lc).
Comments:All Middle American forms retained as subspecies by some (see Hall, 1981; Jones and Engstrom, 1986). Morphometric variation among Middle American forms evaluated by Carleton and Musser (1995) and their morphology contrasted with O. vegetus. Reported karyotypic variation intimates that more than one species occurs among the listed synonyms (Andrades-Miranda et al., 2001a; Gardner and Patton, 1976; Haiduk et al., 1979), whose status, particularly the South American taxa provisionally associated by Carleton and Musser (1995), warrants additional study. Linares (1998), e.g., recognized all Venezuelan populations (except O. griseolus) as O. fulvescens; whereas, Andrades-Miranda et al. (2001a) listed specimens from Roraima, Brazil, as O. cf. messorius, a form described from Guyana; and see Voss et al. (2001) for another regional perspective regarding discrimination and specific assignment of Guianan samples vis a vis lowland populations in Middle America (O. fulvescens) and N Brazil (O. microtis).
