A small to medium-sized Hyperolius frog (males 19–28 mm, females 19–27 mm). Males brownish to green, usually with a white dorsolateral line and rather small gular flap. Male vocal sac may have a pigmented central spot. The females have a uniform green dorsum delimited from the white ventrum by an irregular black lateral line. Pupil horizontal.

H. cinnamomeoventris is among the very few Hyperolius to be found both in forest (although in clearings) and savanna localities. There might be small morphological differences between the bushland and savanna populations and in Cameroun. Amiet has noted differences in the voice between such populations. It is thus not unlikely that two very similar, cryptic species are involved.

H. cinnamomeoventris is very similar to the sympatric H. kivuensis, and some specimens may be impossible to identify. H. cinnamomeoventris is generally smaller, with a shorter snout, smaller gular flap and more distinct light dorsolateral stripe in males. In H. kivuensis both sexes have the same pattern, while in H. cinnamomeoventris the females are green. H. cinnamomeoventris is also very similar to some populations of H. lateralis. The best distinguishing character is the entirely different voice. Finally, it resembles the poorly known H. schoutedeni. The males may be inseparable, but the female of schoutedeni has the same colour-pattern as the male.

Found in both bushland and savanna localities from Cameroun to Uganda and westernmost Kenya, including the Democratic Republic of the Congo southwards to Angola. An older specimen from 1926 may have been from Burundi but its occurrence in that country is not yet confirmed.

Life History, Abundance, Activity, and Special Behaviors
The call is a succession of brief, rather high-pitched distinct clicks, sometimes double, with an indistinct frequency-intensity maximum at about 3500–4000 cps.

The eggs are unpigmented, the jelly milky.

Hyperolius fimbriolatus is a synonym for H. cinnamomeoventris (Lötters et al. 2001).

Wetlands provide fundamental ecosystem services and important habitat for many species, including amphibians. However, for much of the world, we lack basic information on how wetlands are being impacted by human activities, or on policy that protects them from degradation. Mind'je and colleagues (2021) assessed land use change from 2000 to 2018 in an urban wetland in Kigala, Rwanda, by surveying plant and frog diversity to understand the implications of land use change for biological communities, and by surveying local residents with a questionnaire. They found about two-thirds of wetlands that existed in 2000 had been lost by 2018 – urban development, which was just beginning to impinge on the wetland at the beginning of the study, rapidly expanded to cover three-quarters of the study area by the end. A quarter of local residents had moved there within the last 6 years and, beyond new settlements, this wetland is largely impacted by agriculture, irrigation, and waste dumping. Along the development of the wetland, the authors found that the wetland plant and frog communities were now dominated by disturbance-tolerant, generalist species (e.g., Phrynobatrachus natalensis, Kassina senegalensis, Ptychadena spp., Hyperolius kivuensis, H. viridiflavus). More sensitive or specialized amphibians (e.g., Hyperolius lateralis and H. cinnamomeoventris) were no longer present. The authors point to the urgent need for local conservation, education, and restoration work. (Emma Steigerwald)
