The species, named Vulcanops jennyworthyae, inhabited New Zealand around 16 million years ago.
Burrowing bats are a unique group of mammals only found in New Zealand.
These animals not only fly, but crawl along the ground too, and are equipped with specialised claws that enable them to do so.
Vulcanops is the biggest burrowing bat ever found – although it still only weighed around 40 grams.
The finding was described in the journal Scientific Reports.
“Burrowing bats are more closely related to bats living in South America than to others in the south-west Pacific,” said Professor Sue Hand, the first author of the study describing the new species, and a palaeontologist at the University of New South Wales.
Specifically, Prof Hand said burrowing bats such as Vulcanops are related to vampire bats.
However, unlike its blood-feeding cousins, the teeth of this new species suggest it consumed plant material as well as small creatures.
The scientists said the discovery served as a reminder of the diversity of life that has been lost from New Zealand.
Many bats used to inhabit New Zealand, but climate fluctuations are thought to have led to the ultimate demise of all but two species, which still survive today.
