Zamarada phrontisaria Swinhoe 

 (Text-figs 312, 313; PI. 68, figs 722, 723; PL 114, fig. 1031) 



Zamarada phrontisaria Swinhoe, 1904 : 517. LECTOTYPE $, Nigeria (BMNH), here 

 designated [examined]. 



$ O. (PI. 114, fig. 1031). Hyaline area of wings greyish yellow (pi. 4, B3), with a distinct 

 copper-coloured tint in oblique light, and finely edged distally with light brown; discal spot 

 on fore wing large and ovate, silvery grey edged with light brown, that on hind wing slender 

 and light brown; costal area of fore wing irrorate with greyish brown and with silvery grey 

 at base. Non-hyaline terminal area of each wing very pale grey sparsely irrorate with brown; 

 dentate subterminal fascia brownish orange (pi. 5, C6) finely edged distally with silvery white; 

 the brownish orange is diffused to termen in discal area of each wing and to tornus of fore 

 wing; termen slenderly dark brown; cilia chequered very light grey and silvery grey. 

 Underside of non-hyaline terminal area uniformly greyish brown. 



(J genitalia (Text-figs 312, 313). Uncus similar to that of geitaina. Ventral plate of 

 gnathus slightly broadened to an almost truncate apex. Valve: dorsal margin deeply 

 excavate at two-thirds; truncate apex equal in width to greatest width of aedeagus; dorsal 

 process with a slender, digitate, setose projection in basal fourth. Aedeagus dilate at one-half 

 with a weakly developed digitate projection at right side. 



9 genitalia (PI. 68, figs 722, 723). Posterior margin of lamella antevaginalis minutely 

 serrate; a shallow U-shaped excavation at middle of margin. Lamella postvaginalis 

 sclerotized; posterior margin produced medially, as illustrated. Corpus bursae sclerotized 

 in posterior ninth. 



Externally one of the more distinctive species in the genus, readily recognizable 

 by the strikingly copper-coloured hyaline area, apparent in an oblique light and 

 the predominantly very pale grey non-hyaline terminal area. In the male genitalia 

 the form of the valve and aedeagus and in the female genitalia the form of the 

 lamella postvaginalis are diagnostic. 



Distribution. Gambia, Nigeria, Cameroun, Gabon.
