Description
Diagnosis after Otero, 2025 [34856]: Species within Lethenia having two blunt triangular lateral cusplets in anterior, lateral and posterior teeth with complete cutting edges reaching the base of the crown, nearly subrectangular root lobes, especially in anterior and anterolateral teeth, and straight lateral cusplets. On the contrary, Lethenia vanderbroecki has incomplete cutting edges, lingually and laterally recurved cusplets, rounded root lobes and curved lateral cusplets.
