Its type locality is David Haine's Marl Pit, Medford, which is in a Maastrichtian/Paleocene marine horizon in the Hornerstown Formation of New Jersey.

It was recombined as Adocus pectorale by Cope (1871); it was recombined as Adocus pectoralis by Hay (1902); it was recombined as Agomphus pectoralis by Hay (1908), Hay (1930), Hutchison and Weems (1998), Knauss et al. (2011) and Joyce and Bourque (2016).
