| L. Chornogubsky et al. 2009 | Differs from A. mesetaense n. sp. in the following features: smaller size; the anteriormost talonid cusp of the m1 is divided by a deep, and buccolingually oriented groove; labially, the m1 has up to three labial grooves that run vertically, from almost the crown base up to the occlusal surface; in the m2, the central, labial cusp is divided by a deep groove; the lingual cusps are more bulbous (i.e. they are not so buccolingually compressed as in A. mesetaense); p3 is narrower and with a rounded apex; P2 is larger and extremely long (not known in A. mesetaense); P3 is small, with its crown proportionally higher than that of any other known polydolopid (with
L/W ratio almost 1); M1 has at least five lingual cusps; labially, it has two rows of cusps, except at the anterior end, where there is a large, single cusp (also known in Polydolops serra). In M1, the labial-most row of accessory cusps is straighter. |
