Chthonophyle was the daughter of King Sicyon and Zeuxippe.
Chthonophyle was the daughter of Sicyon, the King of Sicyon, named after himself. She and Hermes were the parents of Polybus, another king of Sicyon. She married Phlias, the son of Dionysus and Araethyrea, and had by him another son, Androdamas. Other sources instead give her, and not Araethyrea, as the mother of Phlias with Dionysus.
