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
D. R. Prothero 2008Medium-sized blastomerycine (m1-3 length = 25- 26 mm; p2-4 length = 17-21 mm) with slightly reduced premolars (p2-4 length = 40-70% of m1-3 length). Larger than most specimens of Problastomeryx and Pseudoblastomeryx, with more reduced premolars. Smaller than most specimens of Parablastomeryx. Larger than most specimens of Longirostromeryx, without the elongated rostrum and sym- physis of that taxon.
