The genus most closely related to Satyrium is presumed to be Pachites, which together with Satyrium makes up the subtribeSatyriinae of the Diseae. Historically other species with helmet-shaped flowers e.g. Aceras, Chamorchis and Platanthera, often were included in the genus Satyrium, but far from belonging in the same genus, they no longer are included even within the Satyriinae, but within the tribeOrchideae. In a 2015 classification of Orchidaceae, Satyrium itself was placed in the subtribe Orchidinae.[2]
