Metaphrynella pollicaris

Metaphrynella pollicaris is a species of frog in the family Microhylidae. It is endemic to Peninsular Malaysia.

Description

Males measure and females in snout–vent length. Dorsum is dark olive-brown above, with a variable patterning. Tympanum is hidden. Finger tips are expanded into large disks.

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. Based on the calls, it is abundant where it occurs. It abundance seems to be limited by the availability of tree holes. It can occur as low as asl, but is more common from about upwards.
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. It is known from several protected areas.
