They are light to dark brown on the dorsal surface with varying patterns and camouflage very well with the forest floor.

The upper eyelids and snout are drawn out into long triangular projections, forming what looks like "horns", giving them their common name.

Arms and legs are barred with skin folds and are mottled cream and different shades of brown.

This species lives in permanently damp and cool lowland and submontane rainforests among leaf litter.

Breeding takes place in streams, female frogs attach the eggs to the underside of partially or full submerged rocks or logs.
