Kons, Hugo L. Jr., Robert J. Borth, James T. Vargo, Lance A. Durden, & Jeffrey R. Slotten. 2017. A Lepidoptera Biodiversity Blitz at the Nature Conservancy's Splinter Hill Bog Preserve in Baldwin County, Alabama. Southern Lepidopterists' News 39(2): 93-143.
Note: A more detailed set of genitalia images for a different specimen of this species (from a pitcher plant bog in the Apalachicola National Forest in Liberty County, Florida) is available here. Apparently the ventral most diverticulum is variable in this species with respect to how broad or narrow it is.
