The Bartels flying squirrel ( Hylopetes bartelsi ) is a flying squirrel from the genus of the horseshoe flying squirrel ( Hylopetes ). The species is so far only known from Mount Pangrango on the Indonesian island of Java .

features

The Bartels flying squirrel reaches a head-torso length of about 14 to 20 centimeters. The back color is brown and it resembles the flying squirrel in front of me ( Petinomys vorermanni ). This external similarity was already noted by the first describer Frederick N. Chasen. Today, however, the Bartels flying squirrel is no longer included in the Petinomys genus because of a number of different anatomical features . Special features of the Bartels flying squirrel are the long mustache hair and the ears with tufts of hair. The tail is two-colored at the base.

Like all flying 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 Bartels flying squirrel is endemic to the Indonesian island of Java and so far only known as a type locality from Mount Pangrango in the west of the island . The type specimen comes from a height of 900 meters above sea level.

Way of life

Very little data is available on the way of life of the flying squirrel. The habitat is in the tropical primary forest . Like other species, it is likely to be strictly arboreal and nocturnal. The two specimens present in the first description were caught during clearing work.

Systematics

The Bartels flying squirrel is classified as an independent species within the genus of the horseshoe flying squirrel ( Hylopetes ), which contains a total of nine species. The first scientific description comes from Frederick Nutter Chasen in 1939 using two individuals from Mount Pangrango on the island of Java. Originally the Bartels flying squirrel was assigned to the dwarf flying squirrel ( Petinomys ). It was named after the Dutch zoologist Max Bartels junior , from whose collection the type specimen comes.

No subspecies are distinguished within the species.

Existence, endangerment and protection

The International Union for Conservation of Nature and Natural Resources (IUCN) does not classify the Bartels flying squirrel into a hazard category and list it as "data deficient" due to the limited amount of data available. The species was only detected in one place and there are no current statements about the range, potential sources of danger and the population of the animals.
