Description
Males measure 17–18 mm (0.67–0.71 in) and female(s) 18 mm (0.71 in) in snout–vent length; it is uncertain whether these are juveniles or adults. The snout is short and truncate. The tympanum is visible and about two-thirds of the eye diameter. The toes are one-third webbed and have bluntly pointed tips. The dorsum is light brown and has an elongated X-shaped mark, extending from the eyelids to the groin. The venter is yellowish with brown spots and speckles.[3]
Habitat and conservation
Its natural habitat is, presumably, primary rainforest. The type locality is within the Taman Negara National Park.[1]
