Synonymy 

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

Genus Pyrgus Hübner, [1819]

Verz. bekannt. Schmett. (7): 109. Type-species: Papilio alveolus Hübner, [1803], Samml. europ. Schmett. 1: pl. 92, figs. 466, 467 (= Papilio malvae Linnaeus, 1758, Syst. Nat. (ed. 10) 1: 485, no. 167; synonym), by designation of Westwood [1841], in: Brit. Butts. Transf. (ed. 1): 123. I.C.Z.N. Opinion 278 placed this name on the Official List of Generic Names in Zoology as name no. 706. As a result of the erroneous type-species designation of Hesperia Fabricius, 1793, by Scudder (1875), Proc. Am. Acad. Arts Sci., Boston 10(2): 187-189, most of what is now known as Pyrgus was previously called Hesperia. The action of Plötz (1879), Stettiner Entomol. Ztg. 40(4-6): 179, of citing malvae as the type-species of Carcharodus Hübner, [1819], Verz. bekannt. Schmett. (7): 110, further confused the issue surrounding the identity of Pyrgus. The situation was explained by Hemming (1967), Bull. Brit. Mus. (Nat. Hist.) Entomol. Suppl. 9: 94-95. Carcharodus does not occur in the Nearctic.

      =    ‡Urbanus Hübner, [1806]

Tentamen: [1]. Type-species: Papilio malvae Linnaeus, 1758, Syst. Nat. (ed. 10) 1: 485, no. 167, by monotypy. The Tentamen was suppressed by I.C.Z.N. Opinion 97. Opinion 278 placed Urbanus Hübner [1806] on the Official Index of Rejected and Invalid Generic Names in Zoology as name no. 86.

=    Syrichtus Boisduval, [1834]

Icon. Hist. Lépid. Europ. 1(23): 230. Type-species: Papilio malvae Linnaeus, 1758, Syst. Nat. (ed. 10) 1: 485, no. 167, by designation of Blanchard (1845), Hist. Ins. 2: 348.

=    Scelotrix Rambur, 1858

Cat. Syst. Lépid. Andal.: 63. Type-species: Papilio carthami Hübner, [1813], Samml. europ. Schmett. 1: pl. 143, figs. 726 [actually 720], 723 [not figs. 721-722] (= Papilio fritillarius Poda, 1761, Ins. Mus. graec.: 79, no. 53, as defined by the specimen on pl. 10, fig. 7; synonym), by designation of E. Watson (1893), Proc. Zool. Soc. Lond. 1893(1): 64.

      =    ‡Bremeria Tutt, 1906

Nat. Hist. Brit. Butts. 1(10/11): 296. Type-species: Syrichtus bieti Oberthür, 1886, Étud. Entomol. 11: 26, pl. 6, fig. 50, by designation of Lindsey (1921), Bull. Labs. Nat. Hist. St. Univ. Iowa 9(4): 37. Preoccupied by Bremeria Alpheraky, 1892, in: Romanoff, Mém. Lépid. 6: 7, and Bremeria Moore, 1896, Lepid. Ind. 3(25): 9.

      =    ‡Teleomorpha B. Warren, 1926

Trans. Entomol. Soc. Lond. 74(1): 18, 46, pl. 10, fig. 7. Type-species: Papilio carthami Hübner, [1813], Samml. europ. Schmett.: pl. Pap. 143, figs. 726 [actually 720] ♂, 723 ♂ [not figs. 721-722] (= Papilio fritillarius Poda, 1761, Ins. Mus. graec.: 79, as defined by the specimen on pl. 10, fig. 7), by designation of Hemming (1934), Stylops 3(6): 143. A junior objective synonym of Scelotrix Rambur, 1858.

      =    ‡Hemiteleomorpha B. Warren, 1926

Trans. Entomol. Soc. Lond. 74(1): 19, 72. Type-species: Papilio malvae Linnaeus, 1758, Syst. Nat. (ed. 10) 1: 485, no. 167, by designation of Hemming (1934), Stylops, 3(6): 143. A junior objective synonym of Syrichtus Boisduval, [1834].

=    Ateleomorpha B. Warren, 1926

Trans. Entomol. Soc. Lond. 74(1): 19, 87. Type-species: Hesperia onopordi Rambur, [1842], Faune Entomol. Andal. 2(6): 319, pl. 8, fig. 13, by designation of Hemming (1934), Stylops 3(6): 143.

 

Pyrgus oileus (Linnaeus, 1767)

Syst. Nat. (ed. 12) 1(2): 795-796, no. 269.

Original Combination: P[apilio]. P[lebejus Urbicola]. Oileus

Type Locality: “Algiriae” [Algeria]; suggested to be “Mexico or the U.S.A.” by Evans (1953), Cat. Am. Hesp. Brit. Mus. (3): 221.

Types: Type(s) apparently lost, as noted by Honey and Scoble (2001), Zool. J. Linn. Soc. 132(3): 356.

This name was resurrected by Evans (1953), ibid., to replace syrichtus, a name previously in wide use.

            =    syrichtus (Fabricius, 1775)

Syst. Entomol.: 534, no. 394.

Original Combination: P[apilio]. P[lebejus] U[rbicola] Syrichtus

Type Locality: “America”; Fabricius (1793), Entomol. Syst. 3(1): 349, no. 326, listed “in America meridionali”

Types: Syntypes in ZMUC.

Fabricius (1793), Entomol. Syst. 3(1): 349, no. 326, cited Papilio oileus Linnaeus, 1767, which is further justification for this synonymy.

            =    montivagus Reakirt, [1867]

Proc. Acad. Nat. Sci. Philad. 18(4): 334, no. 33.

Original Combination: Pyrgus montivagus

Type Locality: “Rocky Mountains, Colorado Territory...Mexico, near Vera Cruz”

Types: Syntype(s) in FMNH.

            =    adjutrix Plötz, 1884

Mitt. naturw. Ver. Neu-Vorpomm. 15: 15, no. 38, cited unpublished pl. 882.

Original Combination: [Pyrgus (Scelothrix)] Adjutrix

Type Locality: “Mexico”

Types: Type(s) may be in ZSMC.

Godman (1907), Ann. Mag. Nat. Hist. (7)20(116): 147, suggested that this is “= Hesperia montivaga, Reak.” through an examination of the unpublished drawing made by Plötz.

            =    fumosa (Reverdin, 1919)

Bull. Soc. Lépid. Genève 4(2): 106, pl. 4, fig. 2 ♀ D&V.

Original Combination: [Hesperia syrichtus] var. (ab.?) fumosa

Type Locality: “Mexique (Vera Cruz); Arizona; Florida (Key West); Jamaica; Cuba; Porto-Rico; Brésil (Chapada); Cuba (Guantanamo)”

Types: Location of type(s) not known, probably in MHNG (Reverdin collection).
