The bastard big-footed mouse (Macrotarsomys bastardi) is a species of rodent in the family Nesomyidae. It is found only in Madagascar. Macrotarsomys bastardi is the smallest-bodied of the three species recognized within the genus Macrotarsomys.[1] Two subspecies have been recognized (M. b. occidentalis and M. b. bastardi) however 2004 studies did not find consistent differences between the subspecies and recommended "subspecific epithets be abandoned for this species".[1]
This is a terrestrial species, found primarily in xeric habitats such as dry deciduous forests in the northwest and spiny forests in the south.[1]
