 In 1996, a team led by biologist David Burney collected breccias containing bats and other animals from the cave of Anjohibe in northwestern Madagascar.The bats in the sample were described by Karen Samonds (previously Irwin) in her 2006 Ph.D. dissertation and a 2007 paper.She found several living species in addition to two extinct ones, "Triaenops goodmani" and "Hipposideros besaoka", that she described as new.
