Afri. Centr. Angola: 1–232, provided a key for identification. Mezzasalma, Glaw, Odierna, Petraccioli, and Guarino, 2015, Zool. Anz., 258: 47–53, reported on the karyology of Pseudhymenochirus merlini and Hymenochirus boettgeri as part of a general discussion of karyological evolution in the family. Dewynter, Chirio, Melki, Cordier, and Frétey, 2017, Cah. Fondation Biotope, 11: 14, provided a brief account and photographs of Hymenochirus cf. boettgeri from the Mount Koumouna-Bouali area of Gabon.  Dewynter and Frétey, 2019, Cah.
