Boffius lies within the suborder Cimolodonta and is the only known member of the family Boffiidae (Hahn & Hahn, 1983). The species Boffius splendidus is known from the Lower Paleocene Hainin Formation found in Hainaut, Belgium. It was a relatively large multituberculate. A 2021 study recovers it as part of Djadochtatherioidea.[1]
