Very close to unguicella and often confused with that species. Most

 has the whitish gray areas more evenly colored and less marked with 

 blackish than unguicella. It also has a shorter aedoeagus. 



Male genitalia figured from specimen in National Collection (from 

 Placer County, California " VI-A. H. V.").
