Behn's bat

Behn's bat (Glyphonycteris behnii), also called Behn's big-eared bat or Behn's graybeard bat, is a species of bat in the family Phyllostomidae found in Brazil and Peru. It is known from only six specimens and is considered rare. German naturalist Wilhelm Peters described it in 1865 under the now-defunct genus Schizostoma, from a holotype collected in Cuiaba, Brazil. Gerrit Smith Miller Jr. moved it to Micronycteris in 1898 and Knud Andersen placed it in Glyphonycteris in 1906. The species name honours the German zoologist Wilhelm Friedrich Georg Behn. Its forearm is 44 to 50 millimetres long and the lancet of its nose-leaf is about one and a half times longer than wide. In Brazil it is found in the Cerrado. Judging by the diets of close relatives it feeds on insects and small fruits. The IUCN rated it data deficient in 2016 because so few individuals have been documented, and habitat loss to farmland is a possible threat.
