A forest Hyperolius, males 21–28 mm, females 25–32 mm. No light triangle on the snout. Dorsum greyish green. Ventrum white, femur and extremities bright yellow. Throat intense green (female holotype). Phase J with light yellow-green dorsolateral lines. Pupil horizontal. According to Laurent H. diaphanus is very similar to H. frontalis but lacks the light triangle on the snout. The extremities of H. diaphanus are yellow rather than orange-red. H. diaphanus is also somewhat smaller.
Distribution and Habitat
Country distribution from AmphibiaWeb's database: Congo, the Democratic Republic of the
Only known from the forests of eastern R. D. Congo, from medium altitudes (650-1700 m).
Life History, Abundance, Activity, and Special Behaviors
The males call from trees at some height, in the same way as frontalis and chrysogaster.
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.
