Comment

In the Hyperolius cinnamomeoventris species complex according to the original publication, formerly confused with Hyperolius molleri. Gilbert and Bell, 2017 "2018", Biol. J. Linn. Soc., 123: 1–11, compared call structure of the Hyperolius thomenssi/Hyperolius moleri/Hyperolius drewesi/Hyperolius olivaceus group in Sao Tome and Principe and Central Africa. Channing and Rödel, 2019, Field Guide Frogs & Other Amph. Afr.: 190–191, provided a brief account, photograph, and range map. Bell, Ceríaco, Scheinberg, and Drewes, 2022, in Ceríaco et al. (eds.), Biodiversity Gulf Guinea Islands: 491–494, summarized the literature and systematics of the species.
