Hyperolius chrysogaster Laurent 1950

A medium-sized Hyperolius (female type 29 mm). Males with green dorsum with light dorsolateral lines. Females green, grey or olive. Red-brown canthal area and upper eyelid. Ventrum blue-green, yellow medially. Legs yellow. Dorsum in females green to olive. Ventrum bright green, central part of ventrum and throat yellow. Dorsum and ventrum separated by an irregular greenish-white lateral line. Pupil horizontal (Schiøtz 1999).First described by Laurent (1950).This account was taken primarily from "Treefrogs of Africa" by Arne Schiøtz with kind permission from Edition Chimaira (http://www.chimaira.de/) publishers, Frankfurt am Main.

From transition forests at medium altitudes in eastern R. D. Congo. Kivu from Mount Ruwenzori to Itombwe (Schiøtz 1999). The type locality is at 1,750 m asl (Stuart et al. 2008).

Presumably has larval development in water (Stuart et al. 2008).

This species has a restricted range and its forest habitat is increasingly being lost to agriculture, logging, and encroachment by human settlements (Stuart et al. 2008). Although the population trend is unknown, it is thought to be decreasing. It has not been seen since the 1950s, when it was described by Laurent (1950) and a single subsequent specimen was collected in 1954 within Virunga National Park (Laurent 1972).

Hyperolius chrysogaster is a species of frog in the family Hyperoliidae. It is endemic to the Rwenzori and northern Itombwe Mountains in the eastern Democratic Republic of the Congo. There are also unconfirmed records from Rwanda.

Its natural habitats are high-altitude montane forests. It is threatened by habitat loss caused by logging, agriculture and human settlements. It occurs in the Virunga National Park, possibly also in the Kahuzi-Biéga National Park and Nyungwe Forest National Park (Rwanda).
