• Plexippus, a Pleuronian prince as the son of King Thestius of Pleuron and Eurythemis, daughter of Cleoboea. He was the brother of Althaea, Leda, Hypermnestra, Evippus, Eurypylus and Iphiclus.^[1] Together with his other brother Toxeus, Plexippus participated in the hunt for the Calydonian Boar. He was angry that the prize of the boar's hide had been given to a woman (Atalanta) by his nephew Meleager, who then killed him in the ensuing argument.^[2]
