Madagascar's Rodentia
Madagascar has fewer rodent species than might be expected because the islands slightly larger than Madagascar like Borneo and New Guine support 55 to 60 species.
31 species in two families (Nesomyidae and Muridae) have been described from Madagascar.
The endemic rodents of Madagascar belong to the subfamily Nesomyinae with 8 genera.
- Brachytarsomys
- Eliurus
- Gymnuromys
- Hypogeomys
- Macrotarsomys
- Monticolomys
- Nesomys
- and Voalavo
These genera are spread within 28 species.
The second subfamily Murinae is represented by the three introduced species :
- Rattus rattus
- Rattus norvegicus
- and Mus musculus.
According of the IUCN Red List of Species (2015):
- 07 species are threatened
- 06 Endangered
- and 01 Vulnerable.
