A new species, discovered when two bats were caught at an abandoned miners’ tunnel in western Africa, sports showy swathes of orange fur. Many of the 20 or so new bat species typically named every year are detected through genetic analyses of museum specimen lookalikes. The Nimba Mountains shoot up abruptly from lowland forests, creating little “sky islands” of isolated habitat on peaks, says coauthor Eric Moïse Bakwo Fils, a bat specialist at the University of Maroua in Cameroon.
