 Seven diagnostic features for the group were described which include the moderate size and the broad frontals.The paper referred only "Stratiotosuchus maxhechti" and "Baurusuchus" to the subfamily, making "Stratiotosuchus" "Baurusuchus"' closest relative so far.However, a study in the year 2014 referred a new species called "Aplestosuchus sordidus" to the subfamily, but supported a closer relationship of "Baurususchus" with "Stratiotosuchus" than with it.
