Pyxicephalus cordofanus, also known as Rana cordofana, is a possible species of frog. It is a nomen dubium, a name of unknown application. Franz Steindachner, who described the species in 1867, specified neither a holotype nor syntypes. The syntypes are believed to be at the Natural History Museum, Vienna (NHMW), possibly including the specimen NHMW 2673.[3] The International Union for Conservation of Nature lists it as "data deficient", citing "continuing doubts as to its taxonomic validity, extent of occurrence, status and ecological requirements".[1]

Description

The original species description, based on two specimens, is summarized as follows:[2]

Head considerably narrower, snout longer and sharper than in the two species mentioned earlier [=Pyxicephalus adspersus, Pyxicephalus delalandii]; Tongue roundish, at the posterior margin only very slightly constricted, tongue lobes very short; Back with brownish marbling and small spots; Tympanum (anatomy) indistinctly visible; A small clump on the outer edge of the metatarsus.

Distribution

It is only known from its type locality, "Cordofan", Egypt",[3] an area that falls within the present-day Sudan, thus making this taxon a Sudanese endemic.[1]

Ecology

The ecology of this taxon is unknown, but it is presumed to be an aquatic species.[1]
