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.
