Open encyclopedia reference
Cycloramphus ohausi is a species of frog in the family Cycloramphidae. It is endemic to Serra dos Órgãos in southeastern Brazil. The specific name ohausi honors Friedrich Ohaus, a German physicist and herpetologist. Common name Wandolleck's button frog has been proposed for this species.
Cycloramphus ohausi is a forest species associated with streams. It occurs at elevations of 800–1,200 m (2,600–3,900 ft) above sea level. it was recorded as common in surveys in the 1970s, but more recent surveys have failed to detect it. The known range is protected by the Serra dos Órgãos National Park. The reason for the apparent decline could be chytridiomycosis.
