Unattested as such outside lexicography. Rather, this headword is used in the scholia to Homer and by Aelian, Herodian, Eustathius and others for the "lay" of Dolon in Iliad book 10 (delta 1345); cf. e.g. Odysseia (Odyssey), Diomedeia, Giganteia, Heracleia. (Still commonly used for this.)
'Doloneia' as a city is perhaps an error/aberration for one of the numerous cities called Koloneia (Colonia).
