Hoses small flying squirrel ( Petaurillus hosei ) is a flying squirrel from the genus of the small flying squirrel ( Petaurillus ). It occurs exclusively in the northern part of the island of Borneo .
features
Hose's smallest flying squirrel belongs together with the other species of the genus to the smallest species of flying squirrel, but is about twice as large as Emilia's tiny flying squirrel ( Petaurillus emiliae ). It reaches a head-torso length of about eight to nine centimeters and has a tail about as long. The weight is around 30 grams. The back color is dark brown, the belly side white and the tail gray to dark gray, sometimes with a white tip.
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
Hose's tiny flying squirrel occurs exclusively on the island of Borneo and has been detected there in the Malay states of Sarawak and Sabah as well as in the Sultanate of Brunei .
Way of life
As for the other two species of the genus, almost no data are available on the way of life of the flying squirrel. It is strictly arboreal and nocturnal, sightings are rare. The species probably prefers high, lowland primary forests formed from two-winged fruit trees ( Dipterocarpus ) . Due to their small size and light weight, the animals of the genus are likely to be able to glide more slowly and more deliberately than other flying squirrels.
Systematics
Hoses Kleinstleitörnchen is classified as an independent species within the genus of the Kleinstleitörnchen ( Petaurillus ), which contains a total of three species. The first scientific description comes from Oldfield Thomas from 1900 using an individual from the Toyut River in Baram District in the Malay state of Sarawak.
No subspecies are distinguished within the species.
Existence, endangerment and protection
Because of the limited amount of data available, the International Union for Conservation of Nature and Natural Resources (IUCN) does not classify Hose's tiny sliding squirrel into a hazard category and list it as "data deficient". The species has only been detected in very few places and there are no statements about the distribution area and the population of the animals, concrete surveys have not taken place.
Loss of habitat due to the conversion of forests into agricultural areas and logging is considered to be the main source of risk.
