Sokol, 1977, J. Morphol., 154: 357, considered Pseudhymenochirus a primitive Hymenochirus, rather than an intermediate between Hymenochirus and Xenopus as proposed by Dunn, 1948, Am. Mus. Novit., 1384: 5. Geographically, Pseudhymenochirus merlini is separated by 2000 km from the westernmost Hymenochirus (in Nigeria) (Menzies, 1967, J. West Afr. Sci. Assoc., 12: 23). Not addressed by Pyron and Wiens, 2011, Mol. Phylogenet. Evol., 61: 543-583. Channing, Rödel, and Channing, 2012, Tadpoles of Africa: 288–290, provided information on comparative larval morphology. 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. Channing and Rödel, 2019, Field Guide Frogs & Other Amph. Afr.: 40–41, provided a brief account, photograph, and range map. Klinger-Strobel, Olsson, Glaw, and Müller, 2020, Vert. Zool., Senckenberg, 70: 435 – 446, reported on the development of the skeleton.
