Diagnosis
ReferenceDiagnosis
V. Nesin and O. Kovalchuk 2017A small-sized Allactaga which differs from other extinct and extant species of this genus in the following unique combination of characters: (1) the anterior part of the M1 crown is wider than the main portion of the tooth due to the strong development of anterostyle, anteroloph, and anterocone; (2) the labial arm of the posteroloph is well developed; (3) strongly developed paracone connected with mesocone and mesostyle; (4) metaconid of m1 is isolated on the unworn teeth; (5) entoconid and mesostylid are also sepa- rated; (6) the presence of one major anterior cusp on P4, completely isolated from the posterior ridge (which is arc-shaped).
