OK Zereshk, thank you very much for suggesting that we should read the "Aria" entry of Iranics.  I paste your own EXACT link here "(look up "Aria")"  please everybody, read his own link.  Look up Aria and in there it clearly says: "ARIA, name of a region in the eastern part of the Persian Empire, several times confused with Ariane in the classic sources"  and it also explains more in two sub-items about this confusion.
