The cashmere long-footed bat ( Myotis longipes ) is a species of mouse ears ( Myotis ) within the bats (Chiroptera). It occurs in South Asia and has been found in India , Nepal , Afghanistan and the People's Republic of China .
features
The cashmere long-footed bat is a small species of bat. It reaches a head-torso length of 43 to 46 millimeters and a tail length of 37 to 42 millimeters. The hind feet are 9 to 10 millimeters long. The ears measure 10 to 15 millimeters, they are long and narrow with an equally long, narrow tragus that is about half the length of the ear. The fur is dense and soft, it is black-brown on the back with slightly lighter hair tips, the belly is brown with creamy white hair tips. The length of the hind feet is more than half the length of the shins (tibiae). The forearm length is 36 to 39 millimeters, the flight skin attaches to the rear end of the metatarsal bones . The third metacarpal is only slightly longer than the fourth and fifth.
The skull is strongly built, the cranial skull is rounded and has only a slight or no sagittal crest. The zygomatic arches are wide spreading. The upper premolar P3 is very small and overgrown by the rest of the teeth.
distribution
The Kashmiri long-footed bat is found in South Asia and has been recorded in several disjoint areas in India , western Nepal , Afghanistan and the People's Republic of China . In Afghanistan it occurs in the Lugar and Nangarhar regions , in India in Jammu and Kashmir and in Meghalaya . The altitude distribution ranges from about 300 to about 2000 meters. In China, it was found in the Guizhou Province , although this occurrence is doubted and requires verification. Evidence from Vietnam are considered defective and are probably on confusion with the Chinese water bat ( Myotis laniger ) or Annam long-fingered bat ( Myotis annamiticus ) traced. Descriptions of this kind for individuals originating from Indonesia are also considered to be incorrect.
Way of life
Very little data is available from the distribution areas on the way of life of the Kashmiri long-footed bat. They form large colonies of up to 2000 animals in caves and underground tunnels, crevices in the rock and in walls of empty buildings in the area of primary and secondary forests. They fly out early in the evening and primarily hunt over bodies of water.
Systematics
The cashmere long-footed bat is assigned to the mouse -eared bat (genus Myotis ) as an independent species . The first scientific description comes from the naturalist George Edward Dobson , who based it on individuals from the Bhima Devi Caves in the Kashmir region of India from an altitude of about 1800 meters (6,000 ft.) First as Vespertilio macropus in 1872 and as Vespertilio macropus in 1873 due to the Described in 1854 as Vespertilio longipes . Other synonyms are Vespertilio megalopus Dobson, 1875, and Myotis theobaldi Blyth, 1855. It was partially assigned to the long-footed bat ( Myotis capaccinii ) as a subspecies. Some animals belonging to this species formed the type series of the independent Csorba long-footed bat ( Myotis csorbai ), which is endemic to Nepal.
Apart from the nominate form, no subspecies are distinguished within the species .
Hazard and protection
The species is not classified in a hazard category by the International Union for Conservation of Nature and Natural Resources (IUCN) due to a lack of data on the population, the way of life and the distribution areas, but rather listed as data deficient . Potential threats to the continued existence of habitat stem from loss of habitat and disturbances in resting places, partly due to military conflicts in the distribution areas.
