Description
Original diagnosis after Adnet et al., 2020 [28754]: Fossil species of Ouledia known by uncupsided teeth with combination of characters that distinct the new species from O. sigei and O. casieri: a crown extremely narrow above the neck in uncuspided teeth with an occlusal surface never marked by a large mesio-distal furrow, a smooth enamel excepted on the lingual face of crown with the frequent development of fine alveolar network, a root always longer mesiodistally to the crown with two rounded lobes, hardly separated by a narrow groove.
