Discussion. — This species combines features of j estiva and notata, 

 with wing and abdominal patterns of the former and scutal pattern of 

 the latter. In the male genitalia, the aedeagus and parameres are 

 similar to those of /estiva, but tergum IX is more elongate though not 

 so much as in notata.
