Acyon myctoderos is distinguished from
Acyon herrerae by virtue of the former possessing less sectorial
premolars than the latter and the former having a distinctive posterior cusp on the P2 that the latter
species lacks.
A. myctoderos differs from both
A. herrerae and
Acyon tricuspidatus in that
A. myctoderos has more vertically oriented
hypoconulids and larger hypoconids on
M1-3. == References ==
