Asapholytoceras is a lytoceratid ammonite, originally from the upper Lower Jurassic of southeastern Europe with high, compressed whorls and a sharp angle to the umbilical shoulder. The exposed suture has four primary lobes on either side; the internal dorsal lobe is not cruciform (i.e. shaped in a cross).
Asapholytoceras is included in the lytoceratid subfamily Megalytoceratinae, along with Metrolytoceras and Megalytoceras.
