Abathomphalus is a genus of foraminifera included in the Globotruncanid family. Abathomphalus was described and recorded in 1957 by Bolli, Loeblich, and Tappan and distinguished from related general by the "extra-umbilical position of the primary aperture and in the radial sutures on the umbilical side." Abathomphalus is the sole genus of the subfamily Abathomphalinae, their descriptions being the same. Although Abathomphalus is included in the plantonic order Globigerinida, its description is suggestive of benthic forms.
