English Names
Fraser's Clawed Frog (Frank and Ramus, 1995, Compl. Guide Scient. Common Names Amph. Rept. World: 97).
Fraser's Platanna (Channing, 2001, Amph. Cent. S. Afr.: 237-249).
Distribution
Forested West Africa from Cameroon and Bioko (Equatorial Guinea) eastward throughout the Congo River Basin to the Zaire-Uganda border, and southward to northern Angola.
Comment
Xenopus fraseri forms part of a diploid-polyploid cryptic species group with chromosome numbers of 2n = 36 (Xenopus fraseri ), 2n = 72 (Xenopus amieti, Xenopus andrei, Xenopus boumbaensis), and 2n = 108 (Xenopus ruwenzoriensis) ( Kobel, du Pasquier, Fischberg, and Gloor, 1980, Rev. Suisse Zool., 87: 924; Loumont, 1983, Rev. Suisse Zool., 90: 169). Existing literature records assigned to Xenopus fraseri therefore require reevaluation. De la Riva, 1994, Rev. Esp. Herpetol., 8: 131-132, provided a record for Equatorial Guinea. Frétey and Blanc, 2001, Bull. Soc. Zool. France, 126: 379, reported this species from Gabon. Lasso, Rial, Castroviejo, and De la Riva, 2002, Graellsia, 58: 21-34, provided notes on ecological distribution in Equatorial Guinea. Jacobsen, 2009, Afr. Herp News, 47: 2-20, reported this species from east-north-central Central African Republic.
