If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.

Diagnosis
ReferenceDiagnosis
I. Miján et al. 2017Beneziphius differs from all other members of the family in the following unique combina- tion of characters: ankylosed thickened premaxillae dorsally roofing the mesorostral groove for most of its length (as in Choneziphius, Messapicetus, Ziphirostrum, and other mem- bers of the “Messapicetus clade” sensu Bianucci et al. 2016); presence of a moderately excavated prenarial basin; presence of a medial gap between premaxillary sac fossae; right pre- maxillary sac fossa barely transversely concave (the three latter characters being major differences with Choneziphius); dorsal surface of the maxillae lateral to the prenarial basin covered by excrescences (as in Choneziphius); premaxil- lary crests on the vertex being anterolaterally directed (as in Ziphiinae sensu Bianucci et al. 2016 and members of the “Messapicetus clade”); nasals being not anteriorly longer than the premaxillary crests (differing from Ziphiinae); and nasals lacking an anteromedial excavation (differing from Hyperoodontinae sensu Bianucci et al. 2016).
