This species is known only from the unspecified type locality in Eritrea. It is known only from two old specimens, one of which survives. It is possibly closely related to (or even synonymous with) Pelophylax ridibundus. It is also possible that the species is not even native to Eritrea (Pelophylax ridibundus having been introduced widely elsewhere in the world), and the specimens were perhaps not even collected in that country, but the amphibian fauna of Eritrea is too poorly known for these issues to be resolved at present. Given the current state of knowledge, it is not possible to map this species' range.
Habitat and Ecology
If this is a valid species, it presumably occurs in or near water where is most likely breeds by larval development.
The population status of this species is unknown.
There is no information on threats to this species.
More research is needed to determine whether or not it is a valid species and to improve understanding of its distribution and population status.
Red List Status
Data Deficient (DD)
Listed as Data Deficient because known only from a single specimen of very uncertain provenance, and there continuing doubts as to its taxonomic validity as well as absence of any information on its extent of occurrence, status and ecological requirements.
Largen (1997) examined the only known specimen (a syntype) of this species and concluded that it was most similar to Pelophylax ridibundus. It should, therefore, be placed in the genus Pelophylax. It is possibly a synonym of a member of the P. ridibundus complex.
