lower margin of the hyaline excavation of the fore wing and in the male by the 

 presence of a dilate hind tibia. 



Distinguished externally from lepta, with which it is tentatively associated, by 

 its larger size and differently shaped hyaline excavations of the terminal area. 

 In the male genitalia the form of the valve is clearly diagnostic; the rather similar 

 female genitalia are distinguished by the form of the sterigma and signum.

The NASUTA -Group 



Characterized in the male genitalia by the weakly sclerotized asymmetrical valves 

 and the large bilobate juxta, a structure usually weakly developed in Zamarada. 

 The male hind tibia is simple. 



In the female genitalia the sterigma is weakly developed; the lamella antevaginalis 

 is small and tapered posteriorly. 



The precise affinities of the sole included species have not been established and 

 it has been placed next to the fc^a-group because of the similarities of habitus.
