H. frontalis is known from forests in eastern R. D. Congo and south-western Uganda.

Life History, Abundance, Activity, and Special Behaviors
The call is a twice or thrice repeated brief, hard buzzing with an indistinct frequency-intensity maximum at about 3000 cps.

A clutch consists of approximately 24 light green eggs in a clear jelly, placed above water.

A number of large to medium-sized forest-living Hyperolius have been described or listed by Laurent 1950 and 1972 from Virunga National Park and its vicinity, R. D. Congo. The distinction between them is not well documented and the reference to older type material seems uncertain, and this may reflect on the validity of the current names. Further studies are therefore necessary. They have been treated here under the following names: H. frontalis/, H. diaphanus, H. alticola, H. chrysogaster, H. leucotaenius and H. xenorhinus.
