This is a squat, burrowing frog, likely more widespread than currently assumed. Only a few specimens have been collected, primarily from Bau and nearby areas, including Kuching, in western Sarawak. The images show specimens from Kubah National Park, Sarawak. It is known from heath forests but may also occur in other forest types.

The dorsum is granulate, and the body is robust. The head is short and wide; limbs are short and thick; nostrils are located at the tip of the snout. The toes are basally webbed, with skin fringes visible along their length. The dorsum is tan to brown with a complex dark brown pattern, while the belly is cream or yellow.

The largest known female measured 72 mm. Its life history is poorly understood, except that it inhabits the leaf litter and calls during the day, especially during heavy rainfall. We found some larvae (identified by DNA) at Kubah National Park in a stagnant pool of a small, intermittent forest stream. The tadpole gut did not exhibit the typical coiling seen in other species but was filled with a yellow mass, which we identified as yolk. This suggests that the tadpoles are endotrophic, deriving nutrition from the yolk in their gut. Development in endotrophic species is typically rapid (around 3 weeks), reducing the likelihood of encountering larval stages in the wild.
