Vampyrius
So far, people have only found R. vampyrus in southern Vietnam. The first specimens were found in Bidoup Núi Bà National Park, but scientists think they may also live in many parts of the Langbian Plateau (specifically in Chư Yang Sin National Park and Phước Bình National Park). Later, scientists found them in Ta Dung Nature reserve, Dak Glong District. The area that R. vampyrus extends is approximately 2,082 km2.  The two places where R. vampyrus lives are far apart. The space in between has low elevation, which would make it hard for the frog to live there or travel. Scientists think it used to live in more places, but human beings changed the places where it lives.
