(From: A Catalogue of the Butterflies of the United States and Canada, Jonathan P. Pelham)

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


Satyrium fuliginosa (W. H. Edwards, 1861)

A. Warren (2005), Butts. Ore.: 142-146, discussed the relationship and distinctions between S. fuliginosa and S. semiluna.


Satyrium fuliginosa fuliginosa (W. H. Edwards, 1861)

Proc. Acad. Nat. Sci. Philad. 13(6): 160, 164, no. 10.

Original Combination: Lycaena fuliginosa

Type Locality: “California”; neotype from “Summit,” currently known as Norden, El Dorado County, California.

Types: Neotype in CMNH, designated by Opler (1970), in: F. Brown, Trans. Am. Entomol. Soc. 96(1): 28, fig. 3 ♂ D&V. A subsequent “neotype” in the USNM, was designated by Mattoon and Austin (1998), Syst. W. N. Am. Butts. (53): 682 (this is the lectotype of suasa), who claimed that the first neotype represents populations that Lorquin, the probable collector of the original types, would not have likely sampled. Further research may demonstrate this a faulty assumption.

Species-genus gender conformation is fuliginosum.

=    suasa (Boisduval, 1869)

Annls. Soc. Entomol. Belg. 12: 51, no. 34; figured by Oberthür (1913), Étud. Lépid. Comp. 9(1): pl. 240, fig. 2080 ♂ D&V.

Original Combination: Lycaena Suasa

Type Locality: “le sommet des montagnes de l’est”; defined as “Gold Lake, Sierra County, California” by J. Emmel et al. (1998), Syst. W. N. Am. Butts. (2): 30.

Types: Lectotype in USNM, J. Emmel et al. (1998), Syst. W. N. Am. Butts. (2): 30, figs. 225 ♂ D, 226 ♂ V.
