Hyperolius nienokouensis Rödel 1998

A small, compact Hyperolius (males 19–21 mm, females 23 mm) from south-western Côte d’Ivoire. Dorsum translucent green, sometimes with fine black points. Ventrum in both sexes translucent greyish white. Discs green. No canthal stripe. Pupil horizontal.This species is very similar to H. fusciventris lamtoensis and H. wermuthi. It differs from the former by its translucent ventrum without traces of red marbling and the absence of dark lateral pigmentation. It differs from H. wermuthi by its white, not green ventral pigmentation, but should be compared critically with that species since the differences between them seem very small.This account was taken from "Treefrogs of Africa" by Arne Schiøtz with kind permission from Edition Chimaira (http://www.chimaira.de/) publishers, Frankfurt am Main.

Known from a single forest locality in Tai N. P., Côte d’Ivoire.

The males call from leaves and twigs. The voice is a high, shrill insect-like sound, shorter and lower that that of H. f. lamtoensis. The voice is very similar or identical to that of H. wermuthi.
