| ABSTRACT: | The labyrinthodont superfamily Trematosauroidea is diagnosed. It includes only the family Trematosauridae, which includes the subfamilies Trematosaurinae and Lonchorhynchinae, each of which is diagnosed. The several previously described genera and species of the Lonchorhynchinae are reviewed in chronologic order. A new genus and species is described from a skull, lacking the otic region, from the Meteor Crater Quarry in the Wupatki Member of the Moenkopi Formation, Spathian, of Northern Arizona. Isolated fragments of skulls and jaws from Algeria, Australia, India, Madagascar, and Nova Scotia are diagnosable only to subfamily, but indicate a broad geographic distribution of Lonchorhynchinae and show its geologic range to be from the Griesbachian up into the Anisian.
