Hyperolius picturatus Peters, 1875
EOL Text
A medium-sized Hyperolius (males 21–31 mm, females 26–34 mm) from the forest belt in the western and central part of West Africa. Males with an hourglass pattern and/or broad dorsolateral stripes, females with a uniform dorsum and often with broad light dorsolateral stripes and dark flanks. Pupil horizontal.
Hyperolius picturatus is a very variable species, especially from population to population. Perhaps two sympatric species are involved, one of which is large with an ill-defined gular flap, known from eastern Sierra Leone to eastern Côte d’Ivoire, and a smaller form known from eastern Sierra Leone to Ghana. In morphology this latter form seems to point towards the western H. occidentalis and the eastern H. baumanni as subspecies.
In the field Hyperolius picturatus can be distinguished from H. concolor by its smaller size and shorter snout. H. fusciventris is smaller with different colours. H. v. nitidulus from the savanna has a shorter snout and a much larger gular flap.

This species ranges from northern and eastern Sierra Leone and southern Guinea to southwestern Ghana. It possibly occurs further east than mapped in Ghana in the forests along the Ghana-Togo border. It occurs at low and high altitudes.

Distributed from eastern Sierra Leone to central Ghana in the forest belt. If two species are involved, the one may be restricted to the western part, from Sierra Leone to eastern Côte dIvoire.

The males call from well-concealed positions in bushes, so although not uncommon tracing them can be very difficult. The voice consists of an initial sound followed by a series of clicks. It has a frequency-intensity maximum of 3500-4200 cps, the pitch depending on the size of the calling male.
The eggs have a black and a white pole; the jelly is clear.
