In 1881,
Edward Drinker Cope named the species
Mioclaenus sectorius for jaws with teeth from the
Puerco Formation of
New Mexico. He reassigned it to the new genus
Anisonchus later the same year. That name was
preoccupied by the
beetle Anisonchus, which was erected by
Pierre F.M.A. Dejean in 1833. In 1928,
Embrik Strand proposed
Anisonchanus as a
replacement. ==Notes==
