Guadeloupe big-eyed bat

The Guadeloupe big-eyed bat (Chiroderma improvisum) is a species of bat in the family Phyllostomidae, found on the Lesser Antilles islands of Guadeloupe and Montserrat and documented on Saint Kitts in 2016, which extended its known range by 80 kilometres. It is the largest member of its genus, with a body length of 85 to 88 millimetres, a forearm of 57.5 millimetres and woolly fur that is pale brownish-gray with dark brown tips; some individuals have a white stripe down the back. It was described in 1976 from a holotype collected in 1974 on Basse-Terre, and its species name, Latin for unforeseen, reflects that its describers did not expect a Chiroderma so far from Trinidad and Tobago. A 1994 mitochondrial DNA study found its closest relative to be the hairy big-eyed bat. It is frugivorous, and little is known of its reproduction. The IUCN evaluates it as endangered, uplisted in 2016 from vulnerable; Hurricane Hugo destroyed 90 percent of its population in 1989, and hurricanes and volcanic eruptions remain threats.
