Coordinator notes: This duskywing is very atypical which is why I have taken so long to ponder over it. It has a white hindwing fringe and it is not a Funereal Duskywing and no other duskywing species with a white fringe is likely to stray in from Arizona or Mexico. So this is a tentative determination without an actual specimen to examine.-Ken Davenport
