A large Hyperolius (33–37 mm) from the forest in western West Africa. Dorsum green or olive brown with a broad light canthal stripe, or a light triangle on the snout and broad light dorsolateral stripes of varying length, sometimes terminating just behind the eye but sometimes continuing to the groin. The dorsolateral stripe is not connected to the frontal triangle or canthal stripe. Ventrum bluish green. No light spot on heel. Gular sac of males yellow, limbs and toes green. There is very little difference in size between the sexes and there does not seem to be a juvenile and female phase. Pupil horizontal.

The tadpole has the usual dentition for the genus and has long labial papillae. The tail is long and the eyes are rather large.

Found widely scattered in the dense forest but quite difficult to track, therefore rare in collections although heard whenever suitable localities were visited. Western West Africa from Sierra Leone to central Côte d’Ivoire.

Life History, Abundance, Activity, and Special Behaviors
The males call singly and far from each other from branches in the dense forest, often from high up and rarely below 2–3 metres. The voice is a loud, hard, rather low-pitched click, uttered singly or in series with long intervals.
