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.
