[4] Djoko Iskandar, an Indonesian zoologist, first described the Bornean flat-headed frog based on a single specimen.

[3] This frog grows to a snout-to-vent length of 77 mm (3.0 in) for females and males are slightly smaller.

It has a dorsoventrally flattened body with a broad head with a rounded snout.

[6] This aquatic frog lives in cold, clear, and fast rivers in remote areas of the rain forests of Kalimantan, the Indonesian part of the island of Borneo.

It is threatened by habitat loss from severe degradation of the river habitats because of increased turbidity and toxic metals used in mining and other negative consequences of development on the island.
