Corpus bursae pyriform; scobination chiefly developed at its left side; 

 cestum shaped as a rather narrow, digitate projection on a wealdy 

 sclerotized base; cervix bursae broad, tubular. Sclerotization around

Remarks: This is the only known Proeulia species with a broad 

 dorsal streak on the forewing. In other species, the dorsal triangle 

 is not connected by a streak with the wing base. The genitalia of 

 both sexes of P. triquetra have many characters distinguishing it from 

 other species of the genus.
