Xenopus muelleri (Peters, 1844)

Relatively arid savanna from Burkina Faso eastward across Sudan-Guinea zone to northeastern Dem. Rep. Congo, then south along the East African coastal belt from extreme southern Kenya through Tanzania into northwestern border areas of Rep. South Africa, Botswana and Caprivi region of Nambiia; isolated record in the Ennedi (northeastern Chad).

Comment

Chromosome number 2n = 36 ( Tymowska and Kobel, 1972, Cytogenetics, 11: 271). A savanna species, like Xenopus laevis, but distinguished throughout extensive range by preference for hotter, more lowland regions ( Tinsley, 1981, Monit. Zool. Ital., N.S., Suppl., 15: 135). Poynton and Broadley, 1985, Ann. Natal Mus., 26: 507-508, noted specimens that they regarded as intermediate between Xenopus muelleri and Xenopus laevis laevis, although they did not doubt the species status of the taxa. See account by Inger, 1968, Explor. Parc Natl. Garamba, Miss. H. de Saeger, 52: 18, and also brief accounts by Lambiris, 1988, Lammergeyer, 39: 43-44, Pickersgill, 2007, Frog Search: 55-56, and Du Preez and Carruthers, 2009, Compl. Guide Frogs S. Afr.: 334-335. Rödel, 2000, Herpetofauna W. Afr., 1: 42-46, provided an account and countries within its range. Channing and Howell, 2006, Amph. E. Afr.: 241-243, provided an account as did Measey, 2004, in Minter et al. (eds.), Atlas Frogs S. Afr. Lesotho and Swaziland: 266-267. Padial and De la Riva, 2004, Rev. Esp. Herpetol., 18: 96, suggested that this species will be found in southern Mauritania. Schiøtz, 1963, Vidensk. Medd. Dansk Naturhist. Foren., 125: 14-15, provided records for Nigeria. Mercurio, 2011, Amph. Malawi: 243-244, provided an account for Malawi.
