A medium-sized Hyperolius (males 23–30 mm, females 31 mm) from the forest in the Akwapim-Togo range in easternmost Ghana and adjacent part of Togo, with an almost uniform brown dorsum and a broad light dorsolateral stripe. Pupil horizontal. This form is very similar to H. picturatus, and should possibly be regarded as an eastern subspecies of it. This is not done here because the status of H. picturatus is so uncertain. H. baumanni differs from picturatus, however, in having a larger gular flap, a great constancy in colour-pattern and a different voice.
Distribution and Habitat
Country distribution from AmphibiaWeb's database: Ghana, Togo
A bushland form apparently confined to the forested “peninsula” stretching from the savannas of south-eastern Ghana into Togo. The known localities are within a few miles of each other in Ghana and Togo.
Life History, Abundance, Activity, and Special Behaviors
The call is characteristic, a slow, coarse initial sound followed by a long, accelerating series of clicks. This acceleration is only heard in a few other species such as H. pseudargus. There is a distinct frequency-intensity maximum at about 3000 cps.
The eggs have a black and a white pole, the jelly is clear.
