REVISION OF GENUS ZAMARADA 6r 



Zamarada opposita Prout, 1922 : 180, pi. 1, fig. 23. Holotype <J, Transvaal (TM, Pretoria) 



[examined]. Syn. n. 

 Zamarada ilma Prout; Janse, 1932 : 141, pi. 2, fig. 14. 

 Zamarada opposita Prout; Janse, 1932 : 141, pi. 1, fig. 28. 

 {Zamarada metallicata Warren sensu Prout, 1935 : 13. Misidentification.] 



(£$ (Pi. 99, figs 887, 888). Hyaline area of wings varyingly irrorate with grey; discal spots 

 slender, smoke-brown, that of fore wing silvery grey in middle. Proximal fourth and costa 

 of fore wing and non-hyaline terminal third of each wing greyish yellow (pi. 4, B3) irrorate 

 with smoke-brown to black; dark irroration in terminal third of fore wing often dense anterior 

 of vein M 3 and posterior of vein Cu lb ; slender, broken postmedial fascia, forming distal margin 

 of hyaline area, edged distally with silvery grey. Underside of non-hyaline terminal area 

 greyish orange (pi. 5, B3) suffused with brown in apical area of each wing; in some examples 

 the underside of the non-hyaline terminal area is uniformly greyish brown. 



^ genitalia (Text-figs 73, 74). Uncus very broad, tapered tip minute. Ventral plate of 

 gnathus narrowly rounded at apex. Dorsal process of valve with broad, spatulate projection 

 from one-half. Aedeagus shortly, but coarsely spined near apex. Fulcrum one-half as long 

 as aedeagus, apex broad, hammer-headed and coarsely scobinate. 



$ genitalia (PI. 17, figs 517, 518). Sterigma symmetrical. Posterior margin of lamella 

 postvaginalis crenulate. Lamella antevaginalis minutely scobinate anteriorly. 



Measurements. Fore wing: g 8-5-io-omm; 9. 9-0-10-5 mm. Antennal pectinations: 

 ^ 12 X , $ 3 X diameter of shaft. 



Externally similar to phaeozona and to smaller examples of pulverosa and tosta. 

 The males may be distinguished from phaeozona by the presence of a dilate hind 

 tibia with its pencil of long hair-scales; females may be distinguished from pulverosa 

 by the shorter antennal pectinations. Structurally the broad uncus and the form 

 of the fulcrum in the male genitalia and the form of the sterigma in the female 

 genitalia are diagnostic. 



Examination of the type-specimens of ilma and opposita and comparison of their 

 genitalia with those of known pairs has confirmed their synonymy, which Prout 

 suspected when he described opposita. 



Distribution. Mozambique, Rhodesia, Transvaal, Natal, Botswana, South 

 West Africa.
