Class: Amphibia > Order: Anura > Family: Pipidae > Genus: Xenopus > Species: Xenopus fraseri

Xenopus fraseri Boulenger, 1905, Proc. Zool. Soc. London, 1905: 250. Syntypes: 2 specimens in the BMNH, by original designation; BMNH 1947.2.24.78-79 (formerly 1852.2.22.23-24) recorded as syntypes by museum records; BMNH 1947.2.24.78 designated lectotype by  Evans, Carter, Greenbaum, Gvoždík, Kelley, McLaughlin, Pauwels, Portik, Stanley, Tinsley, Tobias, and Blackburn, 2015, PLoS One, 10(12): e0142823: 34. Type locality: "West Africa . . . therefore probably from Nigeria or Fernando Po [= Bioko, Equatorial Guinea]". See  Evans, Carter, Greenbaum, Gvoždík, Kelley, McLaughlin, Pauwels, Portik, Stanley, Tinsley, Tobias, and Blackburn, 2015, PLoS One, 10(12): e0142823: 35, for discussion of type localities and resolution that the specimens most likely came from Benin or southwestern Nigeria, and not from Bioko I, Ecuatorial Guinea.

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

Comment

 Evans, Carter, Greenbaum, Gvoždík, Kelley, McLaughlin, Pauwels, Portik, Stanley, Tinsley, Tobias, and Blackburn, 2015, PLoS One, 10(12): e0142823: 34, provided an account and restricted the name to the type series from an imprecise type locality and another population in northern Ghana. All previous literature is therefore reasonably assumed to apply to other species in the Xenopus amieti group. The ploidy level of this species is not know, previous reports having been conflated with the tetraploid Xenopus parafraseri (B. Evans, personal commun.). The reports from Equatorial Guinea by De la Riva, 1994, Rev. Esp. Herpetol., 8: 131-132, and  Lasso, Rial, Castroviejo, and De la Riva, 2002, Graellsia, 58: 21-34 (who provided notes on ecological distribution), presumably apply to the newly named Xenopus parafaseri or Xenopus allofraseri. The record from Gabon by Frétey and Blanc, 2001, Bull. Soc. Zool. France, 126: 379, preseumably applies to the newly named Xenopus parafraseri.  Channing, Rödel, and Channing, 2012, Tadpoles of Africa: 295–296, provided information on comparative larval morphology, under this name, but the identification likely corresponds to either Xenopus allofraseri or Xenopus parafaseri, recently named.  Ernst, Schmitz, Wagner, Branquima, and Hölting, 2015, Salamandra, 51: 147–155, discussed the range of nominal Xenopus fraseri (at the time, now partitioned into a number of species), previous records that are questionable due to the great morphological similarity to Xenopus andrei
