Metaphrynella pollicaris (common name: Malaysian treefrog or Malaysian tree-hole frog) is a species of frog in the family Microhylidae.

[3] The species' natural habitats are evergreen rainforest and forest edges.

It lives in hollows in tree trunks and bamboo, where it also reproduces.

While it is secretive, the male call is distinctive and makes it surveyable.

[1] It could be locally threatened by habitat loss, although it may benefit from habitat clearing that encourages the growth of giant bamboos, providing it with its microhabitat.
