TheBeijing barbastelle (Barbastella beijingensis), also known as theBeijing wide-eared bat, is a species ofvesper batendemic toBeijing Municipality,China.[3][4] The species was discovered by Chinese zoology students in 2001 in caves ofFangshan District in southwestern Beijing and was identified as a distinct species by zoologists Zhang Shuyi, Gareth Jones, Zhang Jingshuo and Han Naijian in 2007.[5][6][7]
Phylogenetic evidence supports it not being closely related to other eastern Asian barbastelle species, and instead being the sister species to theArabian barbastelle (B. leucomelas) of northern Africa and the Levant. The clade containing both is the sister group to thewestern barbastelle (B. barbastella).[5]
The Beijing barbastelle is a relatively large member of the genusBarbastella with forearm length of 41.1-46.4 mm and body mass of 10.5-13.9 g.[3] It has dark black dorsal fur with brown-gray tips and lighter ventral fur.[3] The shape of its ear and the frequency of its echolocation calls are distinct from those of its closest relatives, theAsian barbastelle andwestern barbastelle.[7]
The Beijing barbastelle has only been found in caves and one abandoned tunnel inFangshan District, near Yunxiaoling, in a mountainous region with riparian woodland.[3]
As of 2021, it is evaluated asdata deficient by theIUCN.[1]
