The Gobi broad-winged bat ( Eptesicus gobiensis ) is a species of bat from the genus of the broad-winged bat ( Eptesicus ), which belongs to the smooth-nosed family (Vespertilionidae). It lives in desert areas and is spread over large parts of Asia from Iran to Mongolia , the People's Republic of China and Russia .

features

The Gobi broad-winged bat reaches a head-trunk length of about 5.7 to 6.5 centimeters, the tail is about 4.0 to 4.5 millimeters long. The ear length is 10 to 15 millimeters, the rear foot length 9 to 10 millimeters. The forearm has a length of 38 to 42 millimeters. It is a small species of the genus with a dark brown back fur with reddish washings. The ventral side is brownish white.

The skull has a length of 16 millimeters. It is comparatively flat with a flattened supraorbital ridge. The bony snout, the palate and the zygomatic arches are narrow. The outer incisor in the upper jaw is smaller than the inner one.

distribution

The Gobi broad-winged bat is distributed over large parts of Asia from the Alborz region in Iran via Pakistan and northern India , Afghanistan , Nepal , Turkmenistan , the east of Kazakhstan in the Tarbagatai Mountains to Mongolia , the northwest of the People's Republic of China and Russia . In China the species lives in the provinces of Xinjiang and probably also in Xizang , in Russia in the autonomous republic of Tuva . In Mongolia, the species is distributed across all regions of the Gobi and the adjacent Altai Mountains.

Way of life

The Gobi broad-winged bat occurs as a desert species in dry areas and mountain regions. It lives mostly in caves and abandoned buildings. Like other species of the genus, the bat feeds primarily on insects, which it prey on in flight.

Systematics

The Gobi broad-winged bat is classified as an independent species within the genus of the broad-winged bat ( Eptesicus ), which consists of over 30 species. The first scientific description comes from the Russian zoologist Nikolai Alexejewitsch Bobrinski from 1926, who introduced the species on the basis of individuals from the Gobi-Altai in Mongolia. Some of the Gobi Serotine was the Northern bat ( Eptesicus nilssonii assigned), the own species status but has since been validated.

Within the species, together with the nominate form, three subspecies are distinguished:

  • Eptesicus gobiensis gobiensis
  • Eptesicus gobiensis centrasiaticus
  • Eptesicus gobiensis kashgaricus

Hazard and protection

The species is listed as not endangered ( least concern ) by the International Union for Conservation of Nature and Natural Resources (IUCN) due to its large distribution area and large population . The species is not common but is common and no decline in populations is known. There are no existential risks.

Drying water and drought are problematic for the Gobi broad-winged bat, although it is not known whether these changes occur naturally or through human influence in parts of the range.
