      =    ‡Thymele [Fabricius], 1807

In: Illiger, Mag. f. Insektenk. 6: 287, no. 39. Type-species: Papilio tages Linnaeus, 1758, Syst. Nat. (ed. 10) 1: 485, no. 168, by designation of Westwood (1840), Intro. Class. Ins. 2, Syn.: 88. I.C.Z.N. Opinion 232 placed this name on the Official Index of Rejected and Invalid Generic Names in Zoology as name no. 49; it is also a junior objective synonym of Erynnis Schrank, 1801.

      =    ‡”Thymale” Oken, 1815

Lehrbuch Naturgesch. 3(Zool.)(1): 757, 758. Type-species: Papilio tages Linnaeus, 1758, Syst. Nat. (ed. 10) 1: 485, no. 168, by designation of Hemming (1933), Entomol. 66(845): 225. This is possibly an incorrect subsequent spelling of Thymele [Fabricius], 1807, and is also a junior objective synonym of Erynnis Schrank, 1801. The original publication was placed on the list of rejected works in Opinion 417 and this name is unavailable (Code Article 80.7.2).

      =    ‡Astycus Hübner, 1822

Syst.-alph. Verz.: 1, 3, 5, 6, 8-10. Type-species: Papilio tages Linnaeus, 1758, Syst. Nat. (ed. 10) 1: 485, no. 168, by designation of Hemming (1933), Entomol. 66(844): 200. A junior objective synonym of Erynnis Schrank, 1801.

This name is a junior objective synonym of Erynnis Schrank, 1801; it was unjustifiably emended to “Thanatos” by [Dunning & Pickard] [1859], Accentuated List Brit. Lepid.: 6.

Nat. Hist. Brit. Butts. 1(8/9): 261. Type-species: Thanaos marloyi Boisduval, [1834], Icon. Hist. Lépid. Europ. 1(24): 241, pl. 47, figs. 6, 7, by original designation. Preoccupied by Hallia Edwards & Haime, 1850, Brit. foss. Corals (Pal. Soc. 3): lxvi.

persius group Burns, 1964

Erynnis persius (Scudder, 1863)

Forbes (1936), Psyche 43(4): 104-113, demonstrated that Scudder confused this species and baptisiae, both in biological and morphological details. L. Miller and F. Brown (1981), Mem. Lepid. Soc. (2): 21, note 60, claimed to follow Burns (1964), Univ. Calif. Publ. Entomol. 37: 191-194, in their application of names to this complex. Burns, however, advised against using subspecies for E. persius until the group could be studied in more detail. Austin (1981), J. Res. Lepid. 19(4): 242, concurred. The situation remains unclear and subspecies are employed following L. Miller and F. Brown (1981), ibid., and Ferris (1989), Mem. Lepid. Soc. (3): 69.

Proc. Essex Inst. 3: 170, no. 58; figured by Scudder (1889), Butts. E. U. S. & Can. 2(11): pl. 9, fig. 1 ♂ D&V; (9): pl. 36, figs. 1, 2, 3, but some of these figures might represent baptisiae; ♂ valvae figured by Scudder & Burgess (1870), Proc. Boston Soc. Nat. Hist. 13: fig. 1.

Original Combination: Nisoniades Persius

Type Locality: Not specifically stated; “New England” implied from the title of the paper. The “type” is from “Mass” according to W. Forbes (1936), Psyche 43(4): fig. 5. Scudder (1889), Butts. E. U. S. & Can. 2(10): 1472, mentioned “the White Mountains” as one locality where this species was collected.

Types: Syntype (#15835) in MCZ.
