Comment

Loumont, 1983, Rev. Suisse Zool., 90: 176, restricted Xenopus tropicalis to the west of tropical Africa only, and considered that records to the south and east (including the Congo Basin) belong to Xenopus epitropicalis. Synonymy includes Xenopus calcaratus. Most primitive of the Xenopus species, set apart from the rest of the genus by chromosome number (2n=20) (Tymowska, 1973, Cytogenet. Cell Genet., 12: 298), osteology (Estes, 1975, Herpetologica, 31: 269), serum albumins (Bisbee, Baker, Wilson, Hadji-Azimi, and Fischberg, 1977, Science, 195: 785-787), and other characters (Tinsley, 1981, Monit. Zool. Ital., N.S., Suppl., 15: 140). Rödel, 2000, Herpetofauna W. Afr., 1: 36-41, provided an account. Rödel and Branch, 2002, Salamandra, 38: 251, reported the species in Ivory Coast. Schiøtz, 1963, Vidensk. Medd. Dansk Naturhist. Foren., 125: 14, provided records for Nigeria. Emms, Jambang, Bah, Mankali, Rödel, and Barnett, 2005, Herpetol. Bull., London, 94: 6-16, provided records for Gambia. Channing, Rödel, and Channing, 2012, Tadpoles of Africa: 290, provided information on comparative larval morphology (as Silurana tropicalis).
