Remarks
The group is very closely related to the South American Baryus and Mesogenus from Africa and Southeast Asia. According to Muona, 2000; he wrote Stethon and Mesogenus are separated by two autapomorphic features. He further wrote that separation of these two groups may be unnescessary. Further research is needed to clarify their relationships and taxonomic positions.
