Isabelle's ghost bat

Isabelle's ghost bat (Diclidurus isabella) is a pale bat of the family Emballonuridae found in northwestern Brazil, Guyana and Venezuela, and possibly Colombia. Emilie Snethlage discovered it in October 1916, and Oldfield Thomas described it in 1920 under the name Depanycteris isabella from a specimen collected at Manacapuru on the Rio Solimões in Amazonas, Brazil. Although the species name sounds like a personal name, Thomas's notes do not say it honours anyone, and it has been suggested that it refers instead to the color isabelline, in which case isabelline ghost bat would be the better common name. Spelling is also unsettled: the epithet is often written isabellus, but the Mammal Diversity Database uses the original isabella. The bats are pale brown, with the head and shoulders looking whitish, and the forearm is about 54 mm long. The Mammal Diversity Database lists the species as Least Concern.
