The gray-bellied brushtail tree mouse ( Chiropodomys muroides ) is a rodent in the subfamily of Old World mice (Murinae), which is endemic to Borneo .
features
With a head-to-trunk length of 66 to 88 mm and a tail length of 85 to 91 mm, the species is the smallest representative of the brush-tail tree mice genus . It has hind feet 15 to 17 mm long and ears 14 to 19 mm long. Weight information is missing. The head and trunk are covered on the top with light brown to orange-brown fur, while the eponymous gray fur occurs on the underside, occasionally with a brownish tint. The border between the color areas is quite clear, but there is no separating light brown line that various other members of the genus have. On the well-haired brown tail, about 6 mm long hair forms a brush at the tip of the tail. On the short and wide feet, the big toe is equipped with a toenail , while the other toes have slightly curved claws . Females have two teats on each side of the body in the groin area . Deviating from other representatives of the brush-tail tree mice, which have orange-colored tooth enamel on their incisors , the species has light yellow enamel. The ears are covered with fine, almost invisible hair, the eyes are large and the vibrissae are narrow.
Distribution and way of life
Specimens of the gray-bellied brushtail tree mouse were registered in the vicinity of Mount Kinabalu and in the south of the Indonesian province of Kalimantan Utara until 2017 . Presumably the species has a wide distribution area in central and northern areas of Borneo. She lives in forests in the middle of mountains and climbs trees. Typical trees belong to the beech family and wing fruit family .
The structure of the teeth suggests that they are used to open the lignified or thick pericarp of fruit in order to get to the seeds. Further information on the way of life is not available.
Danger
Like other brushtail tree mice, the species can adapt to moderate changes in the landscape. Intensive forestry continues to exist mostly in deeper areas of the mountains. The gray-bellied brushtail tree mouse is found in Kinabalu National Park . However, it is rare and little explored. The IUCN lists the species with insufficient data (data deficient) .
