Vampyrius
The first specimen was discovered in 2008 by Jodi Rowley of the Australian Museum at Sydney, Australia, and her student Le Thi Thuy Duong from Ho Chi Minh City University of Science. They found more in 2009 and 2010, and their team wrote the first paper about the species in the journal Zootaxa in 2010. They called it Rhacophorus vampyrus. In 2012, scientists said this species should be called Rhacophorus calcaneus because of the shapes of the adult frogs' bodies; however, in 2014 the species was reclassified as R. vampyrus through phylogenic research. In 2021, a phylogenetic study found the species to fall far outside Rhacophorus, and instead be the sister genus to Gracixalus, so scientists gave it its own genus, Vampyrius.
