This family the genera Probainognathus and Bonacynodon, known from South America and possibly Lepagia, known when the latter from Europe. The taxon was created by A. S. Romer in 1973. All genera are small animals. Probainognathus, known from a number of specimens, was about 10 centimeters long and closely resembles a mammal in terms of anatomy. Lepagia remains are limited to teeth. These most closely resemble the dentition of other carnivorous cynodonts from the Upper Triassic.
