Cabera erythemaria - Per Rindge, (1956): "Another species that sometimes is confused with erythemaria is Gueneria similaria (Walker). The present species can be separated by the pectinate antennae in the male, as the male antennae of similaria are simple. In addition, the latter species has on the underside of each wing a small discal dot and a faint row of postmedial dots, which are not present in erythemaria."
Anecdotally, G. similaria has a weaker bend in the antemedian line and heavier bend of the costal margin near the base.
