Descriptive notes. Head-body 120-170 mm, tail 144-180 mm, ear 17-20 mm, hindfoot 23-30 mm; weight 48-120 g. The Mamore Arboreal Rice Rat is characterized by large size, relatively long tail, and moderately long pelage (7-9 mm). Dorsum is generally medium buffy brown, dominated by gray hues in some specimens that range from gray to grayish buff; venter appears dull white from chin to inguinal areas in most specimens, although some have encroachment of gray-based hairs over mid-abdomen. Dorsal and ventral pelage tendsto be sharply demarcated, in most specimens accentuated by buff to bright ocherous lateral strip that demarcates upperparts from underparts. Tail is 115-118% of head-body length and brown to dusky brown for most ofits length; proximal section is slightly paler beneath; and short caudal hairs weakly obscure scale rows, without expression of terminal pencil.
Habitat. Humid lower and montane forest mostly at elevations of 200-500 m.
Food and Feeding. The Mamore Arboreal Rice Rat eats fruit and green seeds.
Breeding. No information.
Activity patterns. Mamore Arboreal Rice Rats are nocturnal and arboreal. They nest in tree holes, in dense masses of vines or epiphytes, and among palm leaves; they often invade houses in the forest and seem particularly fond of thatched roofs.
Movements, Home range and Social organization. Mamore Arboreal Rice Rats are solitary.
Status and Conservation. Classified as Least Concern on The IUCN Red List.
