Examination of more than 600 specimens of Copaeodes minima (W. H. Edwards, 1870) (Hesperiidae: Hesperiinae) indicated phenotypic variation throughout its distribution. A dark form occurs in response to low temperatures during development. Its genitalia do not vary concomitantly. Both C. minima and its synonym, Copaeodes rayata Barnes & McDunnough, 1913, were described from the pale form of the species. A lectotype is designated for Copaeodes rayata.
