The Udzungwa lamellar tooth rat ( Otomys uzungwensis ) is a little researched rodent from the genus of the lamellar tooth rat ( Otomys ). It occurs in Tanzania , Malawi and Zambia .

features

The Udzungwa lamellar tooth rat reaches a head-trunk length of 15.5 to 19 cm, a tail length of 8 to 9 cm, a hind foot length of 2.5 to 2.6 cm and an ear length of 2.0 to 2.5 cm . It is a large, sturdy species with a large, blunt head, short tail, and shaggy fur that is pale reddish yellowish-brown on the top and gray on the underside. The two-tone, short tail makes up about 51 percent of the head-torso length. The upper incisors have a single furrow and the lower two deep furrows. The first molar has three lamellae and the third has seven lamellae.

distribution

The Udzungwa lamellar tooth rat occurs in the Udzungwa Mountains and in the Poroto Mountains in southern Tanzania, on the Nyika Plateau in Malawi and in neighboring Zambia.

Habitat and way of life

The Udzungwa lamellar tooth rat lives in montane grasslands at altitudes between 1,800 and 2,750 m. It is probably active during the day or at dusk and is likely to have a purely vegetarian diet. No further information is known about the way of life.

status

The Udzungwa lamellar tooth rat is currently not on the IUCN Red List. In 2006, she was (there in the "high risk" endangered ) listed.

Systematics

The Udzungwa lamellar tooth rat was described as a separate species by Barbara Lawrence and Arthur Loveridge in 1953 . In 1974 it was listed by Xavier Misonne as a synonym and in 1978 by William Frank Harding Ansell as a subspecies of the Ethiopian lamellar tooth rat ( Otomys typus ). Michael D. Carleton and Ellen Schaefer Byrne clarified the validity of this taxon in 2006 and raised it to species status again.
