Zamarada gamma Fletcher 

 (Text-figs 370, 371; PI. 76, figs 759, 760; PI. 118, fig. 1060) 



Zamarada gamma Fletcher, 1958a: 143, pi. 2, figs 13, 15; pi. 5, figs 32, 34, 37. Holotype j\ 

 Malawi (BMNH) [examined]. 



<J 9 (PI- IX 8, fig- 1060). Hyaline area of wings light yellow tinged with green in oblique 

 light, very finely and sparsely striate with grey and finely edged distally with dark brown; 

 costa of fore wing yellowish orange striate with grey; middle of discocellulars marked with 

 a minute, dark dot. Non-hyaline terminal area narrow, greyish brown (pi. 7, D3); subterminal 

 fascia dentate and broken, dark brown, sometimes suffusing to termen in discal area; sometimes 

 dark brown edged proximally with yellow and finely edged distally with glossy buff; cilia 

 chequered greyish yellow and dark brown. Underside of non-hyaline terminal area and 

 slender discal spot on fore wing greyish brown. 



$ genitalia (Text-figs 370, 371). Uncus trapezoid; apical margin shallowly incised medially, 

 two-thirds as broad as base, with a short projection from the ventral surface. Ventral plate 

 of gnathus broadly based and broadly rounded at apex. Valve similar to that of lima, but 

 ventral margin smoothly curved apicad, without a minute digitate projection at point of 

 curve. Fulcrum broadened medially, then finely tapered to scobinate tip. 



9. genitalia (PI. 76, figs 759, 760). Lamella postvaginalis strongly sclerotized, stout and 

 Y-shaped. Lamella antevaginalis almost as broad as long, posterior margin incised medially. 

 Corpus bursae sclerotized at posterior extremity. 



Measurements. Fore wing: £ i6-5-i8-omm; 9 15-18 mm. Antennal pectinations: 

 6* 9 x > $ 3 X diameter of shaft. 



Distinguished externally by the almost immaculate light yellow or greenish 

 tinged hyaline area and narrowly patterned terminal fourth. In the male genitalia 

 the form of the fulcrum, smoothly and evenly broadened medially, and of the 

 valve and in the female the form of the sterigma are diagnostic. 



Distribution. Malawi, Zambia, Zaire, Burundi, Tanzania, Uganda.
