Abstract. Delforge, P.- A Lacedemonian Ophrys [Natural. belges 85 (Orchid. 17) (2004): 235-244]. Originally described from Crete, Ophrys candica subsp. minoa has been sometimes considered as a species, Ophrys minoa, widespread in the Aegean an oriental Mediterranean basins. Various field studies have shown that O. minoa is only a longhorned variant of O. candica (named O. candica var. minoa) and that the so-called O. minoa represents in fact different isolated species which have been progressively described, e.g. O. andria, O. aeoli, O. thesei in the Kyklades (Greece), O. homeri, O. helios, O. halia in the eastern Aegean islands (Greece), O. aramaeorum and O. lyciensis in Anatolia. A Peloponnesian taxon, also included under the old broad concept of O. minoa, remained unnamed. It is described here as Ophrys lacaena sp. nova.

Key-Words: Orchidaceae; genus Ophrys, Ophrys bornmuelleri species group; Ophrys lacaena sp. nova, O. minoa. Flora of Greece.
