Reported total length is 210–285 mm, placing it among the larger Habromys species. Members of the genus are small mice, with some variation in form and color among species.
Habromys are described as arboreal mice of humid montane forests, including cloud and humid pine-oak forests. The study suggests that the larger species, including H. lepturus, are less arboreal than the smaller species.
