(Μυρμιδών), a son of Zeus and Eurymedusa, the daughter of Cleitos, whom Zeus deceived in the disguise of an ant. Her son was for this reason called Myrmidon (from μύρμηξ, an ant), and was regarded as the ancestor of the Myrmidons in Thessaly. He was married to Peisidice, by whom he became the father of Antiphus and Actor. (Apollod. 1.7.3; Apollon. 1.56; Eustath. ad Horn. p. 320; Clem. Alex. Protrept. p. 34; Arnob. ad v. Gent. 4.26.)
