Incan little mastiff bat

It was described as a new species by American zoologist Charles O. Handley.
Although the holotype had been collected in 1915 by Edmund Heller, it was not scientifically described until 1956.
Its species name "phrudus" comes from Ancient Greek "phroudos," meaning "gone" or "disappeared."
Handley chose this name "with allusion to their type locality, the 'Lost City' of Machu Picchu..."
