Differs from Cephalotropis coronatus in having a sharper external occipital crest, an irregular fronto-parietal suture, the maxilla separated by both nasals and premaxillae, the medial edges of the nasals forming a sagittal keel, the facial sulcus running along the posterior edge of the compound posterior process, a slightly conical compound posterior process, rounded tympanic bullae and also in lacking a squamosal cleft.
