The many-spotted wing of this species is similar in pattern to that 

 of williamsi and coronata, but the spots are consistently smaller and 

 paler. It differs from both of those species in having a narrower 

 front, in which character it resembles the smaller species biguttata, 

 which is also found in Puerto Rico and the Virgin Islands. The 

 latter is of course easily distinguished by the few spots in the wing.
