What is "acestodorus"

Acestodorus (Greek ) was a Greek historical writer who is cited by Plutarch, and whose work contained, as it appears, an account of the Battle of Salamis among other things. The time at which he lived is unknown. Stephanus of Byzantium speaks of an Acestodorus of Megalopolis, who wrote a work on cities , but whether this is the same as the above-mentioned writer is not clear.
