Synonymy

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

Genus Callophrys Billberg, 1820

Enum. Ins. Mus. Billb.: 80. Type-species: Papilio rubi Linnaeus, 1758, Syst. Nat. (ed. 10) 1: 483, no. 154, by designation of Scudder (1875), Proc. Am. Acad. Arts Sci., Boston 10(2): 132, no. 202.

 

Callophrys irus (Godart, [1824])

In: Ency. méth. 9(Ins.)(2): (610), 674, no. 177.

Original Combination: Polyommatus Irus

Type Locality: “l’Amerique?”; suggested to be “southern area of New Jersey east of Philadelphia” by Gatrelle (1999), Tax. Rep. Int. Lepid. Surv. 1(6A): 1A. [Camden or Burlington counties, New Jersey]

Types: Holotype in MNHP; figured by K. Johnson (1991), J. Lepid. Soc. 45(2): fig. 18. This same specimen was designated neotype by Gatrelle (1999), Tax. Rep. Int. Lepid. Survey 1(6)(1A): fig. 5 ♂ D&V, because there was a question as to its validity as a syntype. Faynel and Bálint (2004), Bull. Soc. Entomol. Fr. 109(3): 277, 285, considered it the holotype.

=    ‡”balteata” Scudder, 1889

Butts. E. U. S. & Can. 2(6): 837-838.

Original Combination: Incis[alia]. irus [ab.] baltaeta

Type Locality: “Centre, near Albany” [Albany County, New York]

Types: “Holotype” may be in MCZ or NYSM.

 

Callophrys irus arsace (Boisduval & Le Conte, [1835])

Hist. Lépid. Amér. sept. (11): 103-104, pl. 32, figs. 1 ♂ D, 2 ♀ D, 3 ♀ V, 4 larva, 5 pupa; figured by Oberthür (1920), Étud. Lépid. Comp. 17: pl. 505, figs. 4209 ♂ D&V, 4210 ♀ D&V.

Original Combination: T[hecla]. Arsace

Type Locality: “Virginie et la Géorgie”

Types: Described, at least in part, from a John Abbot drawing. The specimens upon which this drawing was based are presumed lost. “Types,” possibly those figured by Oberthür, may be in USNM, but Calhoun (2004), J. Lepid. Soc. 58(3): 156, discussed the dubious nature of such “types” from the Boisduval collection.
