| There is very little specific information about Chapman's Oryzomys, one of the rice rats, which lives in Mexican cloud forests of the Sierra Madre Oriental (Tamaulipas to Veracruz), sistema montañosa (Northern Oaxaca), and Sierra Madre del Sur (Southern Oaxaca and Guerrero), at fairly high elevations.
Please see the Alfaro's Oryzomys (Oryzomys (Handleyomys) alfaroi) and Coues's Rice Rat (Oryzomys couesi) accounts for information about some of the better-known Oryzomys and Handleyomys species.
Recent publications suggest that several species in the Oryzomys group are distinctly different from others and merit a new genus. Handleyomys is the genus preferred by IUCN; MSW3 and ITIS continue to use Oryzomys.
Head and Body: 86-118 mm; Tail 100-140 mm
