Amphidolops , sp. nov. 1

Only three teeth from Laguna Fría are referred to this new species: LIEB-PV 1172, a right m2, and two M1s. This is the smallest species of the genus Amphidolops and differs from A. serrula for a more elongated metacone in M2 and very distinct talonid cusps; M1 is proportionally shorter, with wider stylar shelf; the most posterior labial cusp is the tallest; the metacone in M1 is placed more anteriorly. It differs from Amphidolops sp. nov. 2 (below) in the presence of only one line of labial cusps in M1, and fewer lingual cusps in m2.
