Distinguished externally in both sexes by the tone of the green hyaline area 

 and by the almost uniformly grey, non-hyaline area and in the male by the 

 specialized scaling on the hind leg. In the male genitalia the form of the valve 

 and of the aedeagus and in the female genitalia the form of the sterigma are 

 diagnostic.

 Angola.

Zamarada radula sp. n.

$ $ (PL 102, figs 916, 917). Closely similar in wing colour and pattern to dyscapna, differing 

 in the rather darker green (pi. 29, B5) hyaline area and the brownish orange rather than 

 grey non-hyaline terminal area. 



Distinguished further externally by the denser, darker tufting of the male hind tibia. The 

 femur is edged on its inner surface with long, light buff hair-scales; the tibia is dilate with a 

 dense tuft of greyish brown and light buff hair-scales. 



$ genitalia (Text -figs 126, 127). Apex of valve broadly curved and coarsely scobinate; dorsal 

 margin sclerotized; dorsal process dilate and setose near base; hair-scales of coremata black. 

 Aedeagus with a scobinate, digitate projection at one-half. Fulcrum spatulate and slightly 

 spiral in apical half. Vesica with a small, thorn-like cornutus. 



$ genitalia (PL 28, figs 563, 564). Sterigma with a long, slender, digitate process extending 

 anteriorly to anterior edge of sclerotized posterior third of corpus bursae. 



Measurements. Fore wing: $ 14-15 mm; $ 14 mm. Antennal pectinations: <$ 10 X, 

 $ 5 X diameter of shaft.
