Pseudacris (commonly known as the chorus frogs) is a genus of frogs in the family Hylidae found in North America ranging from the Pacific coastline to the Atlantic.
The name of the genus comes from the Greek pseudes (false) and akris (locust), probably a reference to the repeated rasping trill of most chorus frogs, which is similar to that of the insect. It could also mean ‘false Acris’, distinguishing it from another frog genus.[1]
The species in this genus are disputed. Molecular genetic research shows little consistency due to hybridization between species, making taxonomic organization difficult.[2]
The number of species in this genus is controversial, but Frost et al. list 19 species (all shown here), and AmphibiaWeb lists 17 species (P. hypochondriaca and P. sierra are not recognized):[3][4]
