The DIFFERENS-Group 



The two species included in the group are small, with a wing length of 10 -o- 

 13-5 mm, predominantly yellowish grey to orange-brown in colour with a smooth 

 proximal margin to the non-hyaline terminal area of each wing, with little or no 

 intrusion by the hyaline area between veins M 3 and Cu lb . 



The male genitalia are characterized by the form of the aedeagus, which bears 

 two apical processes, by the form of the fulcrum, consisting of a membranous fold 

 with a slender, longitudinal, sclerotized mid-rib and by the form of the dorsal 

 process of the valve, which is scobinate for its entire length with a projection at 

 about one-third, but none at base. 



In the female genitalia the sterigma is well developed; the corpus bursae is either 

 wholly membranous or partially sclerotized posteriorly; a stellate signum is present.
