SHEIKHDZHEILIA REZVYII AVERIANOV & ARCHIBALD, 2005

(See Appendix 4 for synonymies, referred illustrations, and referred specimens.)

Holotype: ZIN 88438, right dentary fragment with p5, m1, talonid of m2, and alveoli for p4 and m3. Found in 2003 from concentrate obtained in 1998.

Type locality and horizon: SSHD-8, Sheikhdzheili, Kyzylkum Desert, Uzbekistan. Upper part of Khodzhakul Formation, Upper Cretaceous (early Cenomanian).

Revised diagnosis: Differs 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 shifted.
