This species is very close to A. devincta Meyrick, from Peru, but 
is a slightly larger species. The prominent, fleshy socii at once set 
domna apart from devincta. It is further distinguished from devincta 
by the large cornutus, which is nearly half the length of the aedeagus; 
that of devincta is less than one-third the length of the aedeagus.
