Monticolomys koopmani Carleton & Goodman, 1996 , “ Madagascar , Antananarivo Province , Manjakatompo , 1800 m , ca. 19°20’S , 47°26’E .” This species is monotypic. Distribution. Endemic to the Central Highlands and N & E Madagascar. Descriptive notes. Head-body 94-101 mm, tail 134-143 mm; weight 25-27 g. Fur of Koopman’s Forest Mouse is relatively thick, soft, and fine, brownish gray dorsally and lighter gray ventrally. Ears are fairly short. Tail has sparse blackish fur at base, and hairs are progressively more numerous toward tip and sometimes with some white; it does not have distinct tail tuft. Legs are fairly long, with white cream fur, and feet and toes are flesh-pink. Habitat. Eastern humid lowland and montane forest at elevations of 900-2030 m. Food and Feeding. Koopman’s Forest Mouse is presumed to be largely granivorous but may also eat fruits and invertebrates. Breeding. Breeding period of Koopman’s Forest Mouse appears to occur during the rainy season. Females have three pairs of mammae, and largest known litter size is three young. Activity patterns. Koopman'’s Forest Mouse is nocturnal and largely arboreal, but because some individuals have been captured on the ground,it is best considered scansorial. Movements, Home range and Social organization. No information. Status and Conservation. Classified as Least Concern on The IUCN Red List. Koopman’s Forest Mouse is forest-dwelling and is known from a few widely separate sites in the eastern humid forests of Madagascar, mostly from montane forests. Given continued declines in natural forests of this region, particularly those at the lower end ofits elevational range, its mediumand long-term future is uncertain. Bibliography.
