[3] This relatively common frog is a diurnal species living at the borders of slow-flowing streams in high montane tepui habitats, from 1000–1500 metres elevation.

Males call near streams, hiding in leaf-litter, between trunks, or in crevices between rocks.

The tadpoles live in the bottom substrate of small ponds adjacent to streams.

dorsum and limbs are black or dark grey with irregular, variable yellow spots.

There is a yellow line from tip of snout across eyelid to groin, continuing onto anterior thigh and sometimes onto shank.
