Schlechter (1901) thought that Pachites was closely related to
Satyrium Sw. and later formalised his observations by putting the
two genera together in the subtribe Satyriinae Schltr. (Schlechter,
1926). Pachites shares with Satyrium a gynostemium with an
elongate column-part, a pendent anther, non-resupinate flowers
and undifferentiated petals and sepals (Schlechter, 1901; Kurz-
weil, 1996). Pachites differs from Satyrium by its subactino-
morphic perianth, spurless flowers, presence of vestiges of adaxial
stamens and structure of the rostellum (Kurzweil, 1996).
