ReferenceDiagnosis
J. D. Archibald and A. Averianov 2012Differs from other zhelestids by having a deep ectoflexus; stylar cusp B (stylocone) small but distinct; lingual cingula on upper molars
absent. Differs from other zhelestids except Lainodon by protoconid tallest cusp on trigonid; labial postcingulid absent. Differs from other zhelestids except Eoungulatum by preparastyle absent. Differs from other zhelestids except Lainodon and Avitotherium by protocristid oblique. Differs from Avitotherium, Lainodon, and Gallolestes by paraconid not on lingual margin. Differs from Avitotherium, Gallolestes, and Parazhelestes by trigonid angle between 36–49°. Differs from Aspanlestes, Parazhelestes, and Zhelestes
by p5 metaconid absent; p5 lingual cingulid complete.Differs from Aspanlestes and Parazhelestes by p5 paraconid cingulid cusp absent. Differs from Parazhelestes and Eoungulatum by protocone not labially
