New Species of Bat, Hipposideros griffini Discovered in Vietnam

ScienceDaily (Feb. 20, 2012) — A distinctive echolocation frequency led to the discovery of a new species of bat within the genus Hipposideros. Although this bat is similar to the speciesHipposideros armiger, differences in acoustics, size, and DNA between these bats led to the identification of the new species. This new member of the bat community, which has been found in two locations in Vietnam, has been given the scientific name Hipposideros griffini.



The current article of the Journal of Mammalogy reports on findings from a survey of bats in Vietnam over a span of three years. Eleven of 308 bats of the Hipposideros genus that were captured and handled for study displayed differing characteristics from all known taxa of Hipposideros and represent a new species.
Captured bats were measured for features such as forearm length, ear height, nose-leaf width, tooth row length, and body mass. Tissue samples were taken for genetic analysis. Recordings were made inside a flight tent, in front of caves, and under forest canopies, identifying calls of bats when they left their roosts and when they were foraging. Researchers used software for bat call analysis that can display color sonograms and measure frequencies.
