Taxonomy Pelophylax demarchii was described by Italian herpetologist based on two syntypes, of which one is lost. It is uncertain whether it is a valid species; it most closely resembles Pelophylax ridibundus and might be its synonym. Habitat and conservation Ecological requirements, distribution, and current population status of this species are unknown. Consequently, it is listed as "data deficient" in the IUCN Red List of Threatened Species.
