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 echo (W. H. Edwards, 1864)

C. Guppy and J. Shepard (2001), Butts. B. C.: 226-227, Opler and A. Warren (2002), Sci. Names List Butts. N. A.: 28, and A. Warren (2005), Butts. Ore.: 161-165, treated this as a species-level taxon. The inclusion of nigrescens, sidara, and cinerea as subspecies of C. echo should be considered tentative, since some or all of these may be species-level taxa.

Proc. Entomol. Soc. Philad. 2(4): 501, 506-507, no. 8; figured by W. H. Edwards (1884), 2(12): pl. Lycaena 2, fig. 21 ♀ D.

Original Combination: Lycaena Echo

Type Locality: “California”; neotype from “San Francisco, Calif.” [San Francisco County]

Types: Neotype in CMNH, designated by F. Brown and Clench (1970), in: F. Brown, Trans. Am. Entomol. Soc. 96(3): 430-431, fig. 36 ♂ D&V.

=    ‡”nunenmacheri” (Strand, 1915)

Arch. Naturgesch. (A)80(11): 159.

Original Combination: Cyaniris ladon cum ab. nunenmacheri

Type Locality: “Lake Co., Oregon”

Types: “Holotype” possibly in DEI.

 

Celastrina echo nigrescens (Fletcher, 1903)

Proc. & Trans. R. Soc. Can. (2)9(Sect. IV): 213-214, pl. fig. ♂ D, ♀ D.

Original Combination: Lycaena pseudargiolus var. nigrescens

Type Locality: “Kaslo, on Kootenay Lake, British Columbia”

Types: Holotype in USNM.

This taxon was redescribed by Fletcher (1904), Can. Entomol. 36(5): 127, fig. ♂&♀ D. The placement of this taxon as a subspecies of C. echo follows A. Warren (2005), Butts. Ore.: 161-163, but requires additional study.

                   =    bakeri (Clench, 1944)

J. N. Y. Entomol. Soc. 52(3): 274-275.

Original Combination: Lycaenopsis pseudargiolus bakeri

Type Locality: “Baker, Oregon” [Baker City, Baker County]

Types: Holotype in MCZ.

A. Warren (2005), Butts. Ore.: 163, tentatively placed this taxon here.
