The presence of a pleurodiran turtle putatively attributable to Erymnochelys madagascariensis (i.e., the only representative of Erymnochelyini that is part of the current biodiversity) or to a closely related form was recognized, in the early 1990s, for the Lower Pliocene record of the Sinda-Mohari region (Democratic Republic of Congo). The material attributable to it was restricted to postcranial remains. Although some elements of the anterior region of the skull were subsequently found, this taxon had not been analyzed in detail until now. Knowledge about Erymnochelyini has increased remarkably since the 1990s and, especially, during the 21st century. The taxon from the Democratic Republic of Congo is here analyzed in detail, not only considering current knowledge about the lineage but also incorporating new material into this study, highlighting several partial skulls. Thus, it corresponds to one of the members of this lineage represented by a greater number of skulls. It is attributed to a new taxon, Mokelemys mbembe gen. et sp. nov., being the only representative of Erymnochelyini currently known for the Pliocene record.
