Passage 9.38.9
Ἀσπληδόνα δὲ ἐκλιπεῖν τοὺς οἰκήτοράς φασιν ὕδατος σπανίζοντος· γενέσθαι δὲ τὸ ὄνομα ἀπὸ Ἀσπληδόνος τῇ πόλει, τοῦτον δὲ εἶναι νύμφης τε Μιδείας καὶ Ποσειδῶνος. ὁμολογεῖ δὲ καὶ ἔπη σφίσιν ἃ ἐποίησε Χερσίας, ἀνὴρ Ὀρχομένιος· ἐκ δὲ Ποσειδάωνος ἀγακλειτῆς τε Μιδείης Ἀσπληδὼν γένεθʼ υἱὸς ἀνʼ εὐρύχορον πτολίεθρον. Chersias of Orchomenus, unknown location.
They say that Aspledon was abandoned by its inhabitants due to scarcity of water; its name, it is said, came from Aspledon, who was the son of the nymph Mideia and of Poseidon. Supporting their claim are also the verses composed for them by Chersias, a man from Orchomenus: "And from Poseidon and glorious Mideia Aspledon the son was born in the city of broad dancing-grounds."
