Description

A medium-sized Hyperolius (males 22–25 mm, females 29–33 mm) from Cameroun. Gular flap large. Phase J: dorsum yellow with fine light canthal and dorsolateral lines. Ventrum whitish, more or less transparent. Phase F: Dorsum yellow with violet to chocolate-brown, well-defined spots, sometimes so extensive that the ground colour is reduced to fragments. Sides of head and body brown with yellow points. The border between dorsal and lateral pattern always irregular. Underside of legs yellow, ventrum violet with rather small whitish or yellowish spots. Dorsal surface of tibia uniform yellow or with small spots.

This species is similar to H. bolifambae, from which it differs by the more numerous dorsal spots, and larger gular flap. It is also very close to H. steindachneri, of which it is often regarded as a subspecies.

The tadpole has the typical shape and tooth formula for the genus.

This 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.
