Habronyx citrinus Porter

— Fourth gastric tergite of female with black on much of its apical 0.5; hind tibia black with rather dull orange on its basal 0.3-0.4; wings hyaline; front with a fine sharp carina between mid ocellus and level of antennal sockets; mesopleural disc with strong and dense but not even in part reticulately coalescent punctures; discoidella weaker, traceable throughout but in part desclerotized ..................................................................................
