Comprehensive DescriptionRead full entry
A medium-sized Hyperolius (males 21-29 mm, females 30-37 mm). Voice consists of rather atonal clicks. Pattern very variable, but often with yellow dorsum with conspicuous irregular light black-lined canthal and dorsolateral stripes. No white spot on heel. The males have a medium-sized gular flap. Dorsum in males densely beset with very fine asperities, females smooth. Pupil horizontal.
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.
