Synonymy

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

Genus Celastrina Tutt, 1906

Entomol. Rec. & J. Var. 18(5): 131. Type-species: Papilio argiolus Linnaeus, 1758, Syst. Nat. (ed. 10) 1: 483, no. 153, by original designation.

      =    ‡Cyaniriodes Matsumura, 1919

Thous. Ins. Japan, Addit. 3: 736. Type-species: Lycaena ogasawarensis Pryer, 1886, Rhop. nihon. (1): 10-11, no. 24,, pl. 2, fig. 13, by monotypy. Preoccupied by Cyaniriodes de Nicéville, 1890, Butts. India Burmah Ceylon 3: 33.

=    Maslowskia M. M. Omelko & M. A. Omelko, 1984

In: Kononenko et al., Fauna Ekol. Ins. Far East: 25. Type-species: Lycaenopsis filipjevi N. Riley, 1934, Entomol. 67(851): 85-86, pl. 1, figs. 1-6. Kurentsov (1974), Zoogeogr. Far East: 92, is frequently considered to have described this genus (e.g., Korshunov and Ivonin (1990), in: Zolatarenko, Nov. Maloizvest. Vidy Faun. Sib. 22: 77-78); however, Kurentsov mentioned this name without a description; a nomen nudum.

 

Celastrina ladon (Cramer, 1780)

Uitl. Kapellen 3(23): 141, pl. 270, figs. D ♂ D, E ♂ V; (24): 175 (index).

Original Combination: Pap[ilio]. Pleb[ejus]. Rural[is]. Ladon

Type Locality: “Kaap de Goede Hoop” “Cap de bonne Espérance” in error; neotype from “Patuxent River, Anne Arundel Co., Maryland.”

Types: Neotype in MGCL, designated by Clench and L. Miller (1980), J. Lepid. Soc. 34(2): 117, figs. 9 ♂ D, 10 ♂ V.

The determination that ladon is a North American taxon was made by Butler (1885), Entomol. Am. 1(3): 53, and (1900), Can. Entomol. 32(3): 91.

            =    pseudargiolus (Boisduval & Le Conte, [1835])

Hist. Lépid. Amér. sept. (13): 118-119; (12): pl. 36, figs. 1 ♂ D, 2 ♀ D, 3 ♂ V, 4 larva, 5 pupa.

Original Combination: A[rgus]. Pseudargiolus

Type Locality: “grande partie des États-Unis”

Types: Described, at least in part, from a John Abbot drawing. The specimens upon which this drawing was based are probably lost. Oberthür (1920), Étud. Lépid. Comp. 17: pl. 505, figs. 4211 ♂ D&V, 4212 ♀ D&V, figured “types” from the Boisduval collection now in USNM, but Calhoun (2004), J. Lepid. Soc. 58(3): 156, discusses the dubious nature of such “types.”

            =    violacea (W. H. Edwards, 1866)

Proc. Entomol. Soc. Philad. 6(2): 200, 201-202, no. 3; figured by W. H. Edwards (1869), Butts. N. Am. [1](3): pl. Lycaena 1, figs. 1 ♂ D, 2 ♂ V, 3 ♀ D [not 4], and (1884), Butts. N. Am. 2(12): pl. Lycaena 2, figs. 5, 5a ♂ D&V, 6 ♀ D.

Original Combination: Lycaena Violacea

Type Locality: “Kanawha River” [nr. Coalburgh, Kanawha County, West Virginia]

Types: Lectotype in CMNH, designated by Clench (1970), in: F. Brown, Trans. Am. Entomol. Soc. 96(3): 424, fig. 31 ♂ D&V.

D. Wright and Pavulaan (1999), Tax. Rep. Int. Lepid. Surv. 1(9): 5, determined this synonymy.
