Description
Original diagnose Jambura et. al.2021 [29598]: The new species of Pseudocorax is characterized by the combination of the following dental characters: well-developed heterodonty with distinct anterior, two types of lateral, and discrete posterior teeth; crown with smooth cutting edge; main cusp flanked by two well detached lateral heels; mesial heel well developed and rounded; crown overhanging root with narrow, labio-basal bulge; broad lingual neck separating crown and root present; pulp cavity absent; root bulky and holaulacorhize with lingual protuberance bearing a well-marked nutrient groove; well-developed and symmetrical root lobes on anterior teeth, shorter and laterally expanded root lobes on lateral teeth; root lobes basally flattened.
