Type species: Daulestes kulbeckensis Trofimov and Nessov, 1979 , in Nessov and Trofimov 1979.

Included species: Type species and D. inobservabilis ( Nessov, 1982) .

Definition.—The last common ancestor of Daulestes kulbeckensis and D. inobservabilis , plus all of its descendants.

Distribution.— Uzbekistan; Late Cretaceous, Turonian.

Revised diagnosis.—Similar to Asioryctes , Ukhaatherium , and Uchkudukodon gen. nov., and differing from Kennalestes in having P2 smaller than P1 (possible ancestral character, unknown for Bulaklestes ). Similar to Bulaklestes and Uchkudukodon gen. nov., and differing from Kennalestes , Asioryctes , and Ukhaatherium in P4 being two−rooted rather than three−rooted (ancestral character). Similar to Bulaklestes and Uchkudukodon gen. nov., and differing from Kennalestes , Asioryctes , and Ukhaatherium in P4 having small rather than large protocone swelling (ancestral character). P5 has metacone swelling that is absent in Uchkudukodon gen. nov. (ancestral character). (P5s are unknown for Daulestes kulbeckensis and Bulaklestes .) Similar to Asioryctes , Ukhaatherium , Bulaklestes , and Uchkudukodon gen. nov., and differing from Kennalestes in lacking lingual cingula on M1–3 (ancestral character). Metastylar lobe on M2 the same size or smaller than the parastylar lobe, while in Asioryctes , and Ukhaatherium it is smaller and in Kennalestes it is the same size (variable character). Similar to Bulaklestes , Asioryctes , Kennalestes , and Uchkudukodon gen. nov., and differing from Ukhaatherium in having lower canine double−rooted rather than single−rooted (polarity uncertain). Similar to Bulaklestes and Uchkudukodon gen. nov., and differing from Kennalestes , Asioryctes , and Ukhaatherium in lacking diastema between p1 and p2 (ancestral character). Similar to Kennalestes and Uchkudukodon gen. nov., and differing from Asioryctes and Ukhaatherium in lacking paraconid on p4 (derived character, polymorphic in Bulaklestes ). Similar to Kennalestes , Asioryctes , Ukhaatherium , and Uchkudukodon gen. nov., and differing from Bulaklestes in having p5 shorter than p4 (derived character) and in p5 talonid as wide as anterior half of tooth (derived character). Similar to Uchkudukodon gen. nov. in having the average length of m1 1.2–1.4 mm (ancestral character), which differs from Bulaklestes , Asioryctes , Kennalestes , Ukhaatherium , which have an average length of m1 1.6–1.9 (derived character). Similar to Bulaklestes , Uckudukodon , and Kennalestes , and differing from Asioryctes in having little or no constriction of m1–3 trigonids (ancestral character). Intermediate in size between Uckudukodon gen. nov. and Bulaklestes .
