Guayas Province, Ecuador

Located in western Ecuador, bordered to the west by Manabi (northern half) and by the Pacific Ocean (southern half), to the north by Manabi and Los Rios, to the east by Los Rios, Canar and Azuay, and to the south by Eloro Province, Guayas is host to many Saturniidae species.

Those species followed by CL are confirmed by Claude Lemaire, those followed by HK are confirmed by Horst Kach; those followed by LR are confirmed by Luigi Racheli. N.B.: Those species followed by my initials, WO, are unconfirmed, but I feel they might be present.
