Zamarada euryscaphes Prout 

 (PI. 46, figs 635, 636; PI. 108, fig. 971; Map 3) 

 Zamarada euryscaphes Prout, 1915 : 345. Holotype $, Ethiopia (BMNH) [examined]. 



$ (PI. 108, fig. 971). Closely similar to iobathra in colour and structure; distinguished by 

 the extension of the hyaline area to the termen between veins M 3 and C« lb on each wing 

 and by the presence of a well developed discal spot on the hind wing. 



$ genitalia (PI. 46, figs 635, 636). 



O* unknown. 



Measurements. Fore wing: $ 15 mm. Antennal pectinations: $ 8 X diameter of shaft. 



When the male of euryscaphes is known, the relationship with iobathra may 

 prove to be subspecific.
