Etymology
The species name is derived from the Latin dorsualis (meaning of the back, dorsal) in reference to the large, dark brown to fuscous spot present along the dorsal margin of the forewing. The subspecies name fasciata is derived from the Latin fasciatus (meaning banded) in reference to the prominent, dark brown band extending obliquely across the forewing.
