Abstract: In this work, new dental material of Agerinia roselli from its type locality, Les Saleres (NE Spain), is described. An emended diagnosis of the species is provided, together with a redescription of the entire hypodigm from that locality, which was necessary due to some inaccuracies in previous descriptions. The studied material includes 12 teeth (from P3 to M3); the roots of the anterior premolars preserved in a mandible fragment are reported for the first time. Some previously undescribed traits have been identified after the new analysis of this material, such as the P4 with distinct hypoconid and entoconid and the tiny paraconid on the M1. A detailed comparison with other cercamoniines has been made. The body mass of A. roselli, ranging from 650 to 900 g, has also been estimated. The presence of a minuscule paraconid in the M1 is the most reliable criterion for distinguishing this molar from the M2. This is supported by the complete absence of paraconid in four M2 preserved in mandible fragments. The trigonid length seems to be less reliable for distinguishing M1 from M2, due to its high variability in this species. Concluding, this study updates the knowledge about the dental anatomy of A. roselli and demonstrates that it is a valid taxon clearly distinguishable from other cercamoniines.
