Genus Neodolodus Hoffstetter & Soria, 1986

EMENDED DIAGNOSIS. — The dental formula is I 1/2 C 0/1 P 4 / 4 M 3/3. Small, brachydont and bunodont megadolodine litoptern. Neodolodus differs from Megadolodus in its smaller size and having labial and lingual cingulids on m1-3. Neodolodus differs from Bounodus in its smaller size, the P4 being of similar size (not smaller) than M1, and the P4-M1 with a quadrangular outline (not elongated mesiodistally).

REMARKS

In comparison with other Laventan litopterns, Neodolodus differs from Mesolicaphrium sanalfonense ( Cifelli & Guerrero 1997; McGrath et al. 2020a) in the absence of a connection between the protocone and metaconule, having well-developed styles on the upper molars, and the absence of a mesostyle on P3. It differs from Villarroelia totoyoi in that P3-4 are not fully molariform lacking an hypocone, the absence of a mesostyle on P3 and P4, and the presence of a hypocone on M3 ( Cifelli & Guerrero 1997).
