Classification

The subfamily was erected in 2020 by Hendrickx et al., who defined it as all traversodontids more closely related to Arctotraversodon plemmyridon than to Massetognathus pascuali or Gomphodontosuchus brasiliensis.^[1] In their cladistic analysis, they found Arctotraversodontinae to be the sister taxon of the subfamily Gomphodontosuchinae. Below is a cladogram from that analysis:^[1]
