Taxonomy. Oryzomys auriventer nimbosus Anthony, 1926 , “San Antonio, on Rio Ulva, northeastern slope of Tunguragua, Ecuador, altitude 6700 feet [= 2042 m].”
Nephelomys nimbosus was originally considered a subspecies of Oryzomys auriventer . It is smaller than O. auriventer and differs in color and shape of incisive foramina, which resembles that of N. oerex. It was anticipated that O. auriventer would eventually be considered a subspecies of Oryzomys albigularis , which happened in the early 1960s. Subsequently, O. auriventer was reinstated as a species separate from, although related to, O. albigularis , and nimbosus was considered to belong to the same species. When members of the O. albigularis group, including O. auriventer , were transferred to the new genus Nephelomys in 2006, N. nimbosus was recognized as a distinct species. Monotypic.
Distribution. A few localities in E Andes Range of Ecuador. View Figure
Descriptive notes. Head-body 122-144 mm, tail 147-170 mm, ear 19 mm, hindfoot 33 mm; weight 84 g. The Lesser Golden-bellied Rice Rat is medium-sized, with tail longer than head-body length and bicolored or slightly bicolored.
