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
L. Chornogubsky et al. 2009Differs from all other polydolopids except Amphidolops in that the lower molars (and, to a lesser degree, also the upper ones) are considerably longer than wide, and more than four labial cusps are present in the m1. Differs from species of Amphidolops in having a large lingual cusp at the anterior end of the talonid in the m1; at least one, and up to three, vertical furrow(s) that bound the talonid cusps on the labial face of the crown; and two distinct labial rows of cusps in the M1 (i.e. the stylar row and the accessory cusp row; in Amphidolops both rows are almost fused in a single row). Differs from species of Eudolops in being smaller in size and in having a larger p3, with more distinct labial and lingual ribs; upper and lower molars have smaller and less distinct cusps; M1 has a greater difference in width between the anterior and the posterior lobes (the latter being wider); m3 is proportionally smaller. Differs from species of Polydolops in the absence of p2. Differs from Pseudolops in its smaller size; in that the P3 is proportionally shorter and has more marked labial ribs, and in having higher and flatter labial and lingual faces of P3.
