Polypedates macrotis, commonly known as the dark-eared treefrog, sometimes also Bongao tree frog, Bongao bubble-nest frog, Baram whipping frog, or brown-striped tree frog, is a species of frog in the Rhacophoridae family. It is found in the central peninsular Thailand (requiring confirmation), Sumatra, Borneo, and Sulu Archipelago as well as a range of other Philippine islands (Palawan, Busuanga, Calauit, Jolo, and Dumaran).

"Bongao" in the common name refers to Bongao Island, the type locality of Philautus montanus, now synonymized with Polypedates macrotis. On the other hand, "Baram", a district in Sarawak, is the type locality of Polypedates macrotis.


Male Polypedates macrotis grow to a snout–vent length of about 60 mm and females to 85 mm. Tadpoles are up to 60 mm in length. Dorsum is brown with a darker band behind the eye that covers the tympanum, tapering along the side.

Polypedates macrotis is similar to Polypedates leucomystax but differs from it slightly in colouration and body proportions.


Polypedates macrotis deposit their eggs in foam nests attached to leaves or twigs overhanging standing water, such as ponds and ditches.


It is a locally abundant species inhabiting primary forests and edge areas. Adults can be found near small streams, swaps, ponds, puddles, or small pools.
