Taxonomy. Peromyscus (Megadontomys) nelsoni Merriam, 1898 , Jico, 6000 ft (= 1830 m), Veracruz, Mexico .
Megadontomys nelsoni was recognized as subspecies of M. thomasi but elevated to species status. The validity of the genus Megadontomys 1s still much debated. Monotypic.
Distribution. Restricted to high-elevations of Sierra Madre Oriental in CW Veracruz, E Puebla, and N Oaxaca , Mexico. View Figure
Descriptive notes. Head-body 132-146 mm, tail 170-172 mm, ear 20-21 mm, hindfoot 32-35 mm; weight 57 g. Nelson’s Big-toothed Deermouse is large, approaching a medium-sized woodrat ( Neotoma ). It is similar in most characteristics to the Oaxacan Big-toothed Deermouse (M. cryophilus ) and Thomas’s Big-toothed Deermouse ( M. thomasi ), but there are relatively strong genetic differences among the three species. Morphologically, Nelson's Big-toothed Deermouse bridges the gap between the Oaxacan Big-toothed Deermouse and Thomas’s Big-toothed Deermouse, butit is considered closer to the latter.
Habitat. Known only from cloud forests and pine ( Pinus , Pinaceae ) and oak ( Quercus , Fagaceae ) forests, with thickly vegetated areas and dense understories of vines and shrubs, at elevations of 2000-3500 m.
Food and Feeding. Diet probably consists of seeds and other vegetation.
Breeding. Reproduction occurs in March-November, with litters of 2-3 young.
Activity patterns. Nelson's Big-toothed Deermouse is presumably nocturnal.
Movements, Home range and Social organization. No information.
Status and Conservation. Classified as Endangered on The IUCN Red List. Endemic Nelson’s Big-toothed Deermouse has decreasing populations.
