The eyes are large. The tympanum is distinct. The finger and toe tips are enlarged into large discs; the webbing is well-developed in both hands and feet. Dorsal skin is granular and has a lichen-like pattern that grayish during the day and dark brown at night.

It is arboreal; males call from vegetation usually no less than above the ground. The eggs are laid on leaves above small ponds to which the tadpoles eventually fall. Hyperolius hypsiphonus is common in suitable habitat, but it is threatened by habitat loss. It is present in the Lopé National Park in Gabon, and probably in some other protected areas too.
