Description
A rather large Hyperolius (males 28-32 mm, females 30-36 mm) from the central forest. Dorsum warty with hour-glass pattern. Pupil horizontal. No distinct phase F, but females are often uniformly coloured. Belongs to a group together with Hyperolius hutsebauti and H. nimbae, occurring in clearings in the forest belt. Hyperolius tuberculatus is probably closely related to the savanna-living Hyperolius viridiflavus species complex.

Bushland from Cameroun, Gabon, R. Congo? to eastern R. D. Congo south of the Congo River, according to Laurent. Occurs in clearings in the forest belt, as do the other members in its group, H. hutsebauti and H. nimbae.

Comments

Some Hyperolius species shows developmental changes in patterning, with two phases, J (juveniles and many mature males) and F (mature females and some mature males). All newly metamorphosed individuals are phase J, which is normally brownish to green with paired light dorsolateral lines, or an hourglass pattern. All females, and some males, develop into phase F before the first breeding season. Phase F is often colorful and variable, showing the diagnostic color characteristics for the species or subspecies. Either well-defined morphs may be present, or graded variation.

The sample treated by Largen and Dowsett-Lemaire (1991) from R. Congo under the name H. tuberculatus seems to differ in many respects from this treatment of tuberculatus.
