Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| J. D. Archibald and A. Averianov 2012 | Differs from Aspanlestes and Parazhelestes by upper and lower canine singlerooted. Differs from Aspanlestes and Zhelestes by P1 double-rooted; protocone labial shift present. Differs from Zhelestes by diastema between upper canine and premolars absent; diastema posterior to P1 absent; P3 double-rooted. Differs from Aspanlestes, Parazhelestes, and Zhelestes by P5 protocone approaching
paracone in height; P5 metacone large; P5 parastylar lobe larger than metastylar lobe; upper molar preparastyle absent; metacone subequal to larger than paracone; masseteric fossa extends to ventral margin of dentary; m3 smaller than m2. Differs from Parazhelestes by mandibular symphysis at p3 or more posterior. |
