The mustache flying squirrel ( Petinomys genibarbis ) is a flying squirrel from the genus of the dwarf flying squirrel ( Petinomys ). It occurs in the southern area of ​​the peninsula Malaysia as well as on the islands Sumatra , Java and the northern Borneo .

features

The mustache-flying squirrel reaches a head-torso length of about 15.7 to 18 centimeters and a tail length of about 17 to 19 centimeters. The weight is around 70 to 100 grams. The back color is chestnut brown in the area of ​​the shoulders - in some animals also more gray - and changes over the trunk into a reddish brown and to the tail into a grayish brown. The top of the skins is darker brown. The construction side varies from white and creamy white in the area of ​​the throat to a salmon-colored tone on the abdomen and the hind legs.

Like all dwarf gliding squirrels, it has a hairy skin that connects the wrists and ankles and is enlarged by a fold of skin between the hind legs and the base of the tail. The sliding skin is muscular and reinforced at the edge, it can be tensed and relaxed accordingly in order to control the direction of the gliding flight.

distribution

The mustache-flying squirrel lives in the southern area of ​​the peninsula Malaysia as well as on the islands Sumatra , Java and the northern Borneo in the Malaysian states Sarawak and Sabah . It occurs on parts of the national territory of Malaysia, Indonesia and the Sultanate of Brunei .

Way of life

The mustache flying squirrel lives in tropical primary and older secondary forests as well as in the adjacent plantations. Almost no data or observations are available about the way of life of the flying squirrel. In its way of life it probably corresponds to other flying squirrels and is tree-living, largely nocturnal and it feeds on plants.

Systematics

The mustache flying squirrel is classified as an independent species within the genus of the dwarf flying squirrel ( Petinomys ), which contains a total of nine species. The first scientific description comes from Thomas Walker Horsfield from 1822 using an individual from the east of the island of Java , Indonesia. No subspecies are distinguished within the species, but the originally independent species P. sagitta has been integrated into this species.

Existence, endangerment and protection

The mustache squirrel is listed by the International Union for Conservation of Nature and Natural Resources (IUCN) as endangered ("vulnerable"). This status is justified by the significant decline in the past and foreseeable future, which is greater than 30% of the total. This is attributed to the loss of habitat due to the conversion of forests into agricultural areas and logging.
