Anoura aequatoris

Anoura aequatoris, also called the equatorial tailless bat, is a microbat of South America recorded in Bolivia, Colombia, Ecuador and Peru, at high elevations of about 600 to 1,500 metres in montane forest. Einar Lönnberg first described it in 1921 as a subspecies of Anoura caudifer, and in 2006 Mantilla-Meluk and Baker argued that it differs enough to be a full species, a view that is contested. A 2008 study held that splitting it overstated the diversity of the genus and that it should stay a subspecies, so its status is unsettled. It can be told from the related form by a densely furred uropatagium with a fringe of long hairs along its edge, and it is smaller, with a skull about 22.5 millimetres long and forearms of 34.3 to 35.9 millimetres.
