Its type specimen is ANSP 11225, a set of teeth, and it is a 3D body fossil. Its type locality is State Penitentiary, which is in a Serravallian coastal sandstone in the Calvert Formation of Virginia.
It was considered an invalid subgroup of Monachinae by Dewaele et al. (2018) and Berta et al. (2022); it was recombined as Monotherium wymani by Koretsky (2001), Deméré et al. (2003), Berta et al. (2015) and Rule and Park (2024).
