Abstract During 1992, the cloaca of 83 specimens of North American Amphibia from Algonquin Park and Kingston, Ontario, Canada, and from El Paso County, Texas, USA, comprising 14 species in seven families, were checked for opalinids.Opalina martinonae n. sp. was found in five of nineRana sylvatica (Ranidae);O. obtrigonoidea Metcalf, 1923 in six of 11Bufo americanus (Bufonidae) and two of ninePseudacris crucifer (Hylidae);O. pickeringi Metcalf, 1923 in two of ninePseudacris crucifer and in one of sixRana pipiens; andO. virguloidea Metcalf, 1923 in two of sixHyla versicolor (Hylidae).Opalina flava Stokes, 1884 is proposed forCepedea flava (Stokes, 1884) Metcalf, 1923. The occurrence, evolution and biogeography of North AmericanOpalina are discussed.
