A medium-sized Hyperolius (24–27 mm) from the Cameroun forests. Dorsum dark olive brown with no more than four light areas, one on the snout, two on the shoulders and a larger one in the middle of the back. Often small white pearl-like spots on dorsum. A small gular flap, often light, surrounded by pigmented skin. Ventral surfaces bright yellow with much black pigmentation especially on hands and feet. Toes and discs yellow. Canthus rostralis indistinct, rounded. Pupil horizontal.Tadpoles are dark, with a tooth formula of 1/1+1,2.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.

Distributed in the eastern part of southern Cameroun and possibly further to the east.

The call consists of clicks very similar to that of H. endjami and H. acutirostris.Like the similar H. acutirostris it breeds in small bodies of water in trees. Batches of eggs, 10–20 in number, are deposited just above water in the gelatinous jelly. After 13 to 20 days the tadpoles drop into the water.

Hyperolius mosaicus is a species of frog in the family Hyperoliidae. It is found in Cameroon and Gabon, presumably also in the Republic of the Congo and Equatorial Guinea, and possibly in the western Central African Republic. Its natural habitat is tropical moist lowland forests. It is an uncommon, strictly arboreal species that breeds using water in tree holes. Presumably, it is threatened by habitat loss caused by logging, agriculture, and human settlements.
