Biogeography and diversification reported on by Bell, Drewes, Channing, Gvoždík, Kielgast, Lötters, Stuart, and Zamudio, 2015, J. Biogeograph., 42: 65–75, and Bell, Drewes, and Zamudio, 2015, Evolution, 69: 904–915, suggesting that Hyperolius thomensis is the sister taxon of this species, and together the sister taxon of Hyperolius cinnamomeoventris. Records from the island of Principe are now referred to Hyperolius drewesiDrewes and Stoelting, 2004, Proc. California Acad. Sci., Ser. 4, 55: 577–578, discussed (in the sense of including Hyperolius drewesi) habitat and collection localities. Gilbert and Bell, 2017 "2018", Biol. J. Linn. Soc., 123: 1–11, compared call structure of the Hyperolius thomesnsi/Hyperolius moleri/Hyperolius drewesi/Hyperolius olivaceus group in Sao Tome and Principe and Central Africa. Dehling and Sinsch, 2019, Zool. Anz., 280: 65–77, considered this species to be in the Hyperolius cinnamomeoventris group. Bell and Irian, 2019, Biol. J. Linn. Soc., 128: 672–680, reported on a hybrid zone with Hyperolius thomensis. Channing and Rödel, 2019, Field Guide Frogs & Other Amph. Afr.: 192–193, 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. Ceríaco, Marques, Sousa, Veríssimo, Beja, and Ferreira, 2023, ZooKeys, 1168: 41–75, included this species in a report, key, and DNA barcode reference library for the amphibians of São Tomé and Príncipe.
