The Sympistis homogena group

The Sympistis homogena group is closely related to the Sympistis riparia group and includes S. homogena (Grote) comb. n., S. hathor sp. n., S. septu sp. n., S. sobek sp. n., S. ra sp. n., S. khem sp. n., S. cherti sp. n., Sympistis heterogena (A. Blanchard) comb. n., Sympistis arizonensis (Barnes) comb. n., Sympistis pallida (Barnes) comb. n. stat. n. (Fig. E-16), Sympistis columbia (McDunnough) comb. n., Sympistis youngi (McDunnough) comb. n. and Sympistis helena (Mustelin) comb. n.. Wing markings make species determination relatively easy, but genital differences between closely related species are often subtle or non-existent. DNA analysis supports the morphological data, showing that of the 658 COI base pairs examined, there is a 4.56% difference between S. pallida and S. homogena , a 1.88% difference between S. septu and S. hathor , a 4.19% difference between S. arizonensis and S. homogena , a 4.50% difference between S. homogena and S. sobek , and a 4.12% difference between S. cherti and S. sobek . The taxon pallida (Fig. E-16) was described as a race of S. homogena but is more closely related to S. columbia , and given species status here.
