The Sichuan long-eared bat ( Plecotus ariel ) is a little researched bat species in the genus of long-eared bats ( Plecotus ). It is in the region of Kangding in western Sichuan endemic .
features
The Sichuan long ear is similar to the Ward long ear ( Plecotus wardi ), but its back hair is darker gray-brown and the peritoneum is slightly lighter. Only holotype , a female killed in June 1910, is documented. The head-trunk length is 53 mm, the tail length 57 mm, the ear length 43 mm and the forearm length 44 mm. The length of the hair on the back is approximately 9 mm and that of the abdominal hair is 8 mm. Compared to related species, the coat is of medium length. The face and muzzle are almost black. Along with body size, the dark fur is the most telling characteristic that distinguishes this species from related species. The wings are remarkably large. With a length of 7.5 mm, the thumbs of the Sichuan long-eared bat are among the longest in the long-eared bat genus. The skin , the tail and the feet are almost hairless. The brownish toes are not hairy and much stronger than those of Ward's long-eared ear. The medium-sized skull is 17 mm long and is similar to that of the Ognev long -eared ear ( Plecotus ognevi ). The cerebral shell is swollen and the wide process between the eye sockets has no bulge in the frontal bone area. The tympanic membrane is strikingly large.
Habitat and way of life
The holotype was discovered in a tree protection zone. Nothing is known about the way of life of the species.
Systematics
The Sichuan long-eared long-eared species was described by Oldfield Thomas in 1911 as a separate species. In 1938 it was classified by Glover M. Allen as a subspecies Plecotus auritus ariel of the brown long-eared ear . While George Henry Hamilton Tate recognized the taxon again as a species in 1942, John R. Ellerman and Terence Charles Stuart Morrison-Scott regarded the genus Plecotus as monospecific and again classified the Sichuan long-eared as a subspecies of Plecotus auritus . In 2006, Friederike Spitzenberger and her colleagues submitted a revision of the long-eared bats, in which 19 taxa , including Plecotus ariel , were recognized as species.
status
The Sichuan long-eared species is not yet on the IUCN Red List of Threatened Species .
