A very large fully-webbed Leptopelis (females 81-110 mm) from Ihlo du Principe with a large tympanum. Dorsum most often dark green to black, sometimes with many light spots that may give the frog a marbled appearance. Ventrum dark with a granular surface.
Perret demonstrated in 1973 that L. palmatus is confined to Ihlo de Principe in the Guinea Gulf, since the very similar Leptopelis occurring on the mainland is so distinct that it deserves its own name, Leptopelis rufus. Leptopelis palmatus has a comparatively larger tympanum, larger choanae, and differences in the skin texture.

It generally inhabits wet forest along the edges of creeks and streams. It can also be found in forest remnants and possibly in towns. It presumably buries its eggs close to water, with the tadpoles moving into pools or streams where they develop further.
