Delorhynchus is an extinct genus of lanthanosuchoid parareptile known from the late Early Permian (Artinskian age) Garber Formation of Comanche County, Oklahoma. It contains three species: the type species D. priscus is based on a series of maxillae.[3] The second species to be described, D. cifellii, is known from a larger number of well-preserved skulls and skeletal material.[4] The third species, D. multidentatus, is based on a fragmentary skull with several rows of teeth on its jaw.[5]
