What is "karrowalteria"

Karrowalteria is an extinct genus of therocephalian therapsid from the Middle Permian of South Africa. It belongs to the family Scylacosauridae, and resembles the genera Pristerognathus and Scymnosaurus. It is known from a single species, karrowalteria skinneri, named by South African paleontologists A. S. Brink and J. W. Kitching in 1958 to replace the preoccupied walteria which was named in honor of Alex J. Walter Skinner, who found the holotype skull near Laingsburg, Western Cape.
