Thanks Romanus,
I had posted the same question with the Yahoo Group strategikonhellas. A member, by the first name of Kostas, responded with the following:
The Lakedaimonians districts where the citizens "Homoioi" came, were:
Konoura, Limnai, Mesoa, Pitana and later Amyklai. The Amykleans would
normally be Perioikoi. But they strongly resisted to Dorians and finally the
gained the right to be Homoioi (Similars). Perioikoi were most of Pelana and
Selasia. After several wars of conquest against their Greek brothers, they
added: Messena (most of the Helots), Kynouria, Belminatis and also Skyritis
where came the most of their psiloi.
