Taxonomy & Nomenclature



Conservation Status


IUCN status: synonym of Dryophytes japonicus (in error, see below)


The current IUCN RedList assessment for this species (Kuzmin et al., 2017) lists it as a synonym of Dryophytes japonicus. A rather extraordinary situation since the two species are present on different continents. This backtracking from the previous assessment (Grach & Werner, 2008) of "Critically Endangered (Possibly Extinct)" appears to be due to the introduction of Dryophytes japonicus into Israel and subsequent misidentification of specimens of the latter as the former (see Duellman et al., 2016:23).
