Note: the analysis by Wiemers et al. (2009) suggests that the genera Plebejidea (absent from Germany), Agriades, Albulina, Kretania (absent from Germany), Plebejus and Lycaeides are all monophyletic, but are all very closely related and form a larger monophyletic group. Thus, a case could be made to synonymize all these genera under the oldest available name (Plebejus). However, I argue here for retaining the genera: the genetic differentiation between them may be low, even lower than between the species in huge genera like Polyommatus or Agrodiaetus, but the morphological differentiation between them is very clear and most species can easily be assigned to the genera by the color and other wing markings. Thus, I consider the distinct genera (as long as they are all monophyletic, which they seem to be) to be of substantial value especially in terms of species identification and identification keys. The only exception I make is that I lump together the genera Plebejus and Lycaeides, because they are extremely similar and they form a monophyletic group in the analysis of Wiemers et al. (2009). Thus, I regard Lycaeides as a synonym of Plebejus.
