A third species of peccary, discovered in the Chaco of Paraguay, is added to the living members of family Tayassuidae. It is assigned to the genus Catagonus Ameghino, heretofore considered confined to the Pleistocene. The new peccary is conspecific with Catagonus wagneri (Rusconi), a species placed in the related extinct genus Platygonus LeConte when it was described from pre-Hispanic archeological deposits of Argentina.
