Comment

Distinguished by chromosome number (2n = 108), hexaploid with respect to Xenopus laevis, by Tymowska and Fischberg, 1973, Chromosoma, Berlin, 44: 337. Morphology described by Fischberg and Kobel, 1978, Experientia, 34: 1012. Further karyotype description by Tymowska and Fischberg, 1980, Cytogenet. Cell Genet., 27: 39, who cited the authorities for the name Xenopus ruwenzoriensis as Fischberg and Kobel, 1978. No type material was noted in either account. Channing and Howell, 2006, Amph. E. Afr.: 243-244, provided an account. Greenbaum and Chifundera, 2010, Herpetol. Rev., 41: 376, provided records for North Kivu and Oriental provinces of Dem. Rep. Congo. Channing, Rödel, and Channing, 2012, Tadpoles of Africa: 298, provided information on comparative larval morphology. In the Xenopus amieti group of Evans, Carter, Greenbaum, Gvoždík, Kelley, McLaughlin, Pauwels, Portik, Stanley, Tinsley, Tobias, and Blackburn, 2015, PLoS One, 10(12): e0142823: 29.
