Mystacina and Craseonycteris

Mystacina tuberculata (Gray 1843; 6-7cm snout-vent length) is the extant New Zealand lesser short-tailed bat. Distinct from other bats, this one spends a lot of time on the forest floor in deep leaf litter on all fours. The tail extends beyong the uropatagia. It sometimes feeds on nectar with a long hairy tongue, but can be considered omnivorous. The sharp incisor teeth are used to chew out soft tree interiors to create arboreal burrows. The propatagium is small to aid in terrestrial locomotion.
