Description
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.[2]
