The Margareta rats ( Margaretamys ) are a rodent genus from the group of old world mice (Murinae). The genus includes three types.
Margareta rats reach a head body length of 10 to 20 centimeters and a tail length of 15 to 29 centimeters. The fur is brown or gray-brown on the top and white-gray on the underside.
These rodents live on the Indonesian island of Sulawesi . Their habitat are forests from sea level up to 2300 meters above sea level. They are tree dwellers, otherwise little is known about their way of life.
Systematics
The Margareta rats are classified within the Old World mice in the Pithecheir group .
There are three types:
- Margaretamys beccarii in northeastern and central Sulawesi,
- Margaretamys elegans in mountainous countries in Central Sulawesi and
- Margaretamys parvus , also in highlands in Central Sulawesi.
The habitat destruction provides for Margareta rats, the main threat. The IUCN lists M. beccarii as "endangered" ( vulnerable ) and M. elegans as "low risk" ( near threatened ), for M. parvus there is too little data.
