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 albescens Plötz, 1884

Original Combination: [Pyrgus (Pyrgus)] Albescens

This taxon has been considered a subspecies or form of P. communis by various authors (e.g., Lindsey et al. (1931), Denison Univ. Bull. 31(2), J. Sci. Lab. 26(1): 46, Tilden (1965), J. Lepid. Soc. 19(2): 91-94, Austin (1981), J. Res. Lepid. 19(4): 242, and (1986), J. Lepid. Soc. 40(1): 55-58), but Burns (2000), J. Lepid. Soc. 54(2): 52-71, and Calhoun (2002), J. Lepid. Soc. 56(2): 98-103, corroborated its species-level status.

            =    occidentalis Skinner, 1906

Entomol. News 17(3): 96; figured by Skinner (1906), Entomol. News 17(8): pl. 12, middle row left ♂&♀ D, middle row right ♂&♀ V.
