Holotype as Anthrax sinuosa female by Wiedemann, 1821. Type Locality: Georgia. In the Naturhistorisches Museum Wien (Vienna), Austria.
Holotype as Anthrax nycthemera by Macquart, 1840. Type Locality: Georgia. In the Muséum National d'Histoire Naturelle, Paris, France.
Holotype as Anthrax concisa by Macquart, 1840. Type Locality: Carolina. In the In the Muséum National d'Histoire Naturelle, Paris, France.
Holotype as Anthrax assimilis by Macquart, 1846. Type Locality: Texas. Originally in the early Eugene Pilate Collection, destroyed by fire during Civil War in Louisiana. Pilate’s later collection is in the Dayton Museum, Ohio.
Hemipenthes jaennickeana has a nearly identical wing infuscation pattern to H. sinuosa, but it can be distinguished by the presence of a crossvein between R4 and R2+3 (which H. sinuosa lacks).
In the south, H. blanchardiana and H. scylla also have the extended brown to wing tip.
In Canada, this is the only species with extended brown to wing tip.
