What role, if any, did Pylos, Messene, Megalopolis, and Argos play in this war?

Tegea, Mantinea, Orchomenos, and Elis also allied with Athens, but prior to 268 BC were they controlled by Macedon? Was Argos under Macedonian control? I know Elis had gotten it's independence a few years before the war.

Did any cities north of Attica participate in the League?
