The clade includes the genera Neonematherium , Sibyllotherium , Valgipes , Proscelidodon , Catonyx and Scelidotherium , and was recovered in all analyses performed in this study. The relationships among those genera were consistent among analyses: ( Neonematherium , ( Sibyllotherium , ( Valgipes , ( Proscelidodon , ( Catonyx , Scelidotherium ))))). It was recovered in all but one analysis, par_EW, in which Neonematherium and Sibyllotherium are in a polytomy with the remaining scelidotheriines.
Scelidotheriinae was supported by six synapomorphies, all but one recovered by both methods: flat occlusal surface of molariforms; subtriangular Mf1 cross-section (BI); roughly horizontal profile of dorsal surface of the skull, in lateral view; presence of ventral extension in maxilla for dental alveoli; medial palatal process of maxilla extending anterior to lateral process; and well-developed, free-standing paracondylar processes.
