The South Indian mouse ( Mus famulus ) is a little researched rodent from the genus of the mice ( Mus ). Their occurrence is limited to four fragmented areas in the Nilgiri Mountains in the Indian states of Kerala and Tamil Nadu .
features
The head-trunk length is 90 to 100 mm, the tail length 71 to 94 mm, the ear length 12 to 17 mm and the hind foot length 18.5 to 21 mm. The weight is 23 to 30.4 g. The upper side is colored dark brown, the underside medium brown. The tail length is approximately 90 percent of the head-trunk length. The fur is soft. The females have three pairs of teats .
habitat
The South Indian mouse inhabits the Shola. This is an indigenous, evergreen, tropical and subtropical mountain forest of the southern Western Ghats , which is dominated by pine, eucalyptus and acacia as well as fire and cold resistant grasses. The South Indian mouse occurs at altitudes between 1,540 and 2,400 m.
Way of life
The South Indian mouse is terrestrial and nocturnal. No further information is known about the way of life.
status
The South Indian mouse is in the IUCN (Red List in the "high risk" endangered ) listed.
Systematics
The South Indian mouse was placed in the subgenus Coelomys by Oldfield Thomas in 1915 . In 2003 Pascale Chevret, Paulina D. Jenkins and François Catzeflis published a phylogenetic study in which this species was transferred to the Mus subgenus on the basis of molecular genetic and morphological properties . The next related species are the Falbmaus ( Mus cervicolor ) and the Laos-mouse ( Mus fragilicauda ). In 1961, John Ellerman listed three subspecies: Mus famalus famulus , Mus famalus cooki and Mus famalus popaeus . Mus cookii is now considered an independent species. Mus famalus popaeus was classified as a subspecies of the fallow vole in 1992 by Gordon Barclay Corbet and John Edwards Hill . This taxon is currently considered a synonym for the fallow mouse.
