Original Combination: H[esperia]. R[urales]. Ceraunus

Type Locality: “America meridionalis Insulis”; defined as “Jamaica and Hispaniola” by W. Comstock and Huntington (1943), Ann. N. Y. Acad.

Lamas (2004g), Atl. Neotrop. Lepid. Chcklst. Part 4A: 139, placed ceraunus and all of its subspecies under Hemiargus hanno (Stoll, 1790), Aanhangs. Werk Uitl. Kapellen Pieter Cramer (3): 170, pl. 39, fig. 2 ♂ D, 2B ♂ V; 183 (index). This view was supported by W. Comstock and Huntington (1943), Ann. N. Y. Acad. Sci. 45(2): 106-107, N. Riley (1975), Field Guide Butts. W. Indies: 109, pl. 12, figs. 12a, 12b, F. Brown and Heineman (1972), Jamaica Butts.: 252-253, D. Smith et al. (1989), J. Lepid. Soc. 43(4): 282, and (1994), Butts.
