Zamarada aclea Prout 

 (Text-figs 236, 237; PL 49, figs 648, 649; PL 109, fig. 979) 



Zamarada aclea Prout, 191 2 : 200. Holotype §, Rhodesia (BMNH) [examined]. 

 Zamarada aclea Prout; Janse, 1932 : 143, pi. 10, fig. 1. [Broken genitalia.] 



$ $ (PI. 109, .rig. 979). Hyaline area of wings greenish white; discal spots wanting. 

 Non-hyaline terminal area of each wing very slender and only shallowly excavate between 

 veins M 3 and Cit lb . variable in colour, from greyish orange (pi. 5, B5) to brownish orange 

 (pi. 5, C5) suffused proximally with grey; dentate subterminal fascia orange brown slenderly 

 edged distally with light yellow, marked on anterior half of fore wing only. Underside of 

 non-hyaline terminal area similar to upperside, but grey suffusion more strongly marked. 



^ genitalia (Text-figs 236, 237). Valves asymmetrical. Left valve with short, thorn-like 

 projection from mid-apical margin; apex of dorsal margin produced in short, thorn-like form. 

 Right valve: apex of dorsal margin similar to that of left valve; mid-apical margin with minute, 

 thorn-like projection. 



$ genitalia (PI. 49, figs 648, 649). Closely similar to aequilitmata, differing in the more 

 slender spined projections from the lamella antevaginalis. 



Measurements. Fore wing: ^ 12-16 mm; § 14 mm. Antennal pectinations: $ 9 X, 

 diameter of shaft. 



Distinguished externally by the appreciably narrower non-hyaline terminal area 

 of each wing and by the absence of discal spots. In the male genitalia the form of 

 the asymmetrical valves and in the female genitalia the slender, lateral projections 

 from the lamella antevaginalis are diagnostic. 



Distribution. Rhodesia.
