Mystacina is the sole surviving genus of the family Mystacinidae. The New Zealand lesser short-tailed bat is the only member of this group confirmed to survive today, since the closely related New Zealand greater short-tailed bat possibly went extinct as recently as 1965. A third species, Mystacina miocenalis, is known from the Middle Miocene some 19-16 million years ago.
