According to a notice in Der Kleine Pauly by Ernst Meyer, Amarynthos was a deme of Eretria on Euboea with a sanctuary of Artemis Amarysia and a great annual festival. See Strabo 10,1,10 p. 448 and Livy 35.38.3. There was also a cult of Artemis Amarysia in the Attic deme of Athmonon. Amarynthos was located at H. Vathia about 10 km east of Eretria.
But looking at a map of Greece it looks like the ancient name of Amarynthos has been restored.
isn’t that temple located in the home island kingdom of wonder woman?
Yup, it’s implied in the article that the reason for the renaming is the discoveries associated with this.
