REVISION OF GENUS ZAMARADA 149 



<J 9- (PI. 112, fig. 1015). Hyaline area of wings tinged with pale yellow, free from dark 

 irroration; discal spots dark grey. Costa of fore wing pale yellow, immaculate; basal area 

 of fore wing and non-hyaline terminal area of each wing reddish brown (pi. 9 D4) very lightly 

 irrorate with reddish golden (pi. 6, C7) and dark brown (pi. 6, F5, teak) ; dentate subterminal 

 fascia strongly marked, dark brown mixed with reddish golden and finely edged distally with 

 pale buff; cilia greyish orange. 



<J genitalia (Text-figs 250-251 A). Uncus tapered, tip produced and bluntly rounded. 

 Ventral plate of gnathus well developed, asymmetrical and tapered to a narrowly rounded 

 tip inclined to the right side. Juxta very large for Zamarada, bilobate at apex. Valves 

 asymmetrical; dorsal process simple, without projection. Aedeagus slightly spiral in shape. 

 Fulcrum subequal in length to aedeagus. Vesica without cornutus. 



9 genitalia (PI. 52, figs 660, 661). Sterigma weakly developed; lamella antevaginalis 

 tapered posteriorly to rounded tip. Corpus bursae wholly membranous. 



Measurements. Fore wing: $ 10-iimm; 9 9 - 5-i2-omm. Antennal pectinations: 

 (J 13 X, $ 5 X diameter of shaft. 



Externally closely similar to lepta, but distinguished by its slightly smaller size, 

 darker non-hyaline terminal area of each wing, greyish orange unchequered cilia 

 and, in the male, by the simple hind tibia. In the male genitalia the large, 

 bilobate juxta and the form of the asymmetrical valves and in the female the 

 form of the weakly developed sterigma are diagnostic. 



Male specimens from Efulen in Cameroun and from Entebbe in Uganda differ 

 in the more deeply cleft apex of the left valve and in the longer right valve 

 (Text-fig. 251). Externally the Cameroun specimens are closely similar to typical 

 nasuta; those from W. Uganda are slightly larger ($9 fore wing 13 mm) and of a 

 redder grey in the non-hyaline terminal area, closely resembling lepta, with which 

 they occur. 



Biology. A male specimen was reared in Ghana by G. S. Cotterell from a 

 larva feeding on Dichrostachys glomeratus (Forsk.) Chiov. (=D. cinerea (Linnaeus) 

 Wight & Arnott) (Leguminosae). 



Distribution. West Africa, Senegal to Cameroun, Niger, Sudan, Uganda.
