Dionys. Hal. A. R. I, c. 72: (Fowler 2000,68; Damastes fr. 3)
“After summarizing the sacrifices in Argos and how everything was done with each, he says that Aineas came from the Molossoi to Italy with Odysseus and became the founder of the city. And he named it.”
῾Ο τὰς ἱερείας τὰς ἐν ῎Αργει καὶ τὰ καθ’ ἑκάστην πραχθέντα συναγαγὼν Αἰνείαν φησὶν ἐκ Μολοττῶν εἰς ᾿Ιταλίαν ἐλθόντα μετ’ ᾿Οδυσσέως, οἰκιστὴν γενέσθαι τῆς πόλεως· ὀνομάσαι
As Fowler (Early Greek Mythography 2. 2013, 564-5) notes, the Greek could mean either that Aeneas came to Italy with Odysseus or came to Italy and founded the city with Odysseus. Either way, the story is certainly not one at home in our Odyssey.
Note though that the close collocation of Odysseus and Aeneas appears in Hesiod’s Theogony too (1008-1013):
“And well-crowned Kythereia gave birth to Aeneias
after having lovely sex with the hero Anchises
on the hills of windy Ida with its many valleys.
And Kirke the daughter of Helios the son of Hyperion
after sex with enduring-minded Odysseus
gave birth to Agrios and blameless and strong Latinus.”
Αἰνείαν δ’ ἄρ’ ἔτικτεν ἐυστέφανος Κυθέρεια,
᾿Αγχίσῃ ἥρωι μιγεῖσ’ ἐρατῇ φιλότητι
῎Ιδης ἐν κορυφῇσι πολυπτύχου ἠνεμοέσσης.
Κίρκη δ’ ᾿Ηελίου θυγάτηρ ῾Υπεριονίδαο
γείνατ’ ᾿Οδυσσῆος ταλασίφρονος ἐν φιλότητι
῎Αγριον ἠδὲ Λατῖνον ἀμύμονά τε κρατερόν τε·
It may be important that a possible reference is here too to Italy (in the name Latinus). In other texts, there is still an indirect association between Aeneas, Odysseus and the founding of Rome:
Geoponica, 126.96.36.199 (10th Century CE)
“For they say that Latinus was the brother of Telegonos and the son of Circe. and the father-in-law of Aeneas, that he founded the Akropolis before Aeneas arrived, and discovered laurel there.”
τὸ παλάτιον ὠνομάσθη, ἀπὸ τῆς ἐπικλήσεως δάφνης τῆς ἐν ῾Ρώμῃ. φασὶ γὰρ Λατῖνον τὸν Τηλεγόνου μὲν ἀδελφόν, Κίρκης δὲ παῖδα, πενθερὸν δὲ Αἰνείου, κτίζοντα τὴν ἀκρόπολιν πρὸ τῆς Αἰνείου παρουσίας, εὑρηκέναι ἐκεῖ δάφνην.
