Zamarada pinheyi Fletcher, 1956 : 41, pi. 1. fig. 7. Holotype $, Tanzania (BMNH) 

 [examined]. 



(J § (PI. 114, fig. 1035). Hyaline area of wings almost immaculate and finely edged distally 

 with brown, costa of fore wing buff, costal edge suffused with a vinaceous-tinged brown 

 proximally; discal spots minute. Non-hyaline terminal area 2-3 mm broad at apex of fore 

 wing, slender elsewhere; greyish orange (pi. 6, B3) irrorate proximally with light brown (pi. 7, 

 D4) ; cilia buff. Underside of non-hyaline terminal area brownish grey. 



£ genitalia (Text-figs 322, 323). Distinguished from acosmeta by the more slender, tapered 

 valve and by the form of the fulcrum, in which the right arm is longer than the left and the 

 central core of each is scobinate almost to the base. 



$ genitalia (PI. 69, figs 728, 729). Distinguished from acosmeta by the more slender leaf- 

 like process on the sterigma, the serrate posterior edge of which is twice as wide as the base 

 of its hollow stem. 



Measurements. Fore wing: $ 16-17 mm; ? 1 6-5-1 8 -o mm. Antennal pectinations 

 J 12 X, $ 3 X diameter of shaft.
