Genus Satyrium Scudder, 1876

Bull. Buffalo Soc. Nat. Sci. 3: 106, no. 8. Type-species: Lycaena fuliginosa W. H. Edwards, 1861, Proc. Acad. Nat. Sci. Philad. 13(6): 160, 164, no. 10, by original designation. The generic synonymy below generally follows Clench (1979), J. Lepid. Soc. 32(4): 277-281, with the caveat that there is disagreement over the rank of several taxa. The group is in need of revision.
