Habitat. Indomalayan Pencil-tailed Tree Mice are found in numerous habitat types, including lowland evergreen, semi-evergreen and deciduous tropical forests, and hill to lower montane tropical forests. They occur in both primary and secondary forests and plantations, and are sometimes captured in close proximity to human habitations, sometimes inside dwellings. Many captures have been made in areas of secondary forest with bamboo understory. Occurs at elevations from sea level to more than 1615 m.

Movements, Home range and Social organization. Movements of Indomalayan Penciltailed Tree Mice were studied in Selangor, Malaysia, by means of mark-recapture trapping methods. Most captures were associated with bamboo clumps, and mean distance traveled for all individuals captured twice or more was 12 - 1 m (range 3 - 28 m). It was concluded thatthis speciesis “ behaviorally confined to a spatial area not exceeding twice its specialized niche requirements ” (i. e. the bamboo clumps), but dispersal capacity of a species that relies on such a narrow and ephemeral microhabitat was questioned. Although this observation remains valid locally, the wider records for the Indomalayan Pencil-tailed Tree Mouse clearly demonstrate its capacity to exist within and disperse across a much wider range of habitats. Solitary lifestyle inferred from capture records in nests of single adults or females with dependent young. Violent behavior when “ unfriendly ” individuals were housed together, often resulting in deaths, was also reported.

Deskripsieng
Descriptive notes. Head — body 69 - 102 mm, tail 94 - 143 mm, ear 13 - 19 mm, hindfoot 15 - 22 mm; weight 15 - 32 g. A medium-sized species of Chiropodomys, with typical body form for this arboreal genus — short head with large eyes, moderately large ears, and elongate, narrow vibrissae; slender body clothed in short, soft, dense fur with inconspicuous scattered guard hairs; short broad hindfoot with nailed hallux and short, recurved claws on second to fourth digits; elongate, well-furred tail with distinct terminal tuft; and two mammae on each side, both inguinal. All populations of the Indomalayan Pencil-tailed Tree Mouse have brown to reddish-brown fur on upperparts, either white or cream fur on underparts, white to tan foreand hindfeet, and tufted tail that is evenly colored above and below, and lacks any pale tipping. Facial patterning includes buffy fur on cheeks and dark eye-ring. Malay and Sundaic populations are brightly colored, reddish-brown above, pure white below, with intervening ocherousstrip, and tail uniformly brown to dark brown; compared with mainland Asian populations, they are generally smaller but have longer skull with proportionally smaller molar rows and smaller auditory bullae. Populations north of Isthmus of Kra are usually larger-bodied, with longer feet but proportionally shorter tail that is paler brown; upperparts are duller brown to tan, and underparts usually cream rather than white, with no or weakly developed intervening ocherous strip. An individual from Doi Khun Tan in Thailand has prominent black tail brush that terminates in distinct white tip. Juveniles have shorter and finer pelage, dorsum grayish brown andventer white or cream. Karyotypes of individuals from Peninsular Malaysia with 2 n = 42, with 18 acrocentric pairs, one metacentric pair, and one submetacentric pair; and metacentric X and submetacentric Y chromosomes that are both unusually large; FN = 48; nucleolar organizer regions occur on one acrocentric pair and one metacentric pair. Specimens from Thailand with 42 telocentric chromosomes; FN = 42; Y chromosome entirely heterochromatic. In both chromosomaltypes, pericentromeric regions of most autosomes with C-banding heterochromatin. Spermatozoa measure 102 pm in total length, head short with 5 pm hook, midpiece relatively short (22 pm); overall, resemble spermatozoa of Mus species.
