Zamarada excavata Bethune-Baker 

 (Text-figs 114-117; PI. 26, figs 553-556; PI. 102, fig. 913) 

 Zamarada excavata Bethune-Baker, 1913 : 573. 



cJO- (PI. 102, fig. 913). Colour and pattern of vestiture and wings similar to those of dentata 

 and psectra, but differing on the upperside in the suffusion of the non-hyaline terminal area 

 of each wing with greyish ruby (pi. 12, D4), densely and evenly in the female, to a lesser extent 

 in the male; subterminal fascia rarely marked, then with brownish yellow (pi. 5, C7) interneural 

 spots except between veins M 3 and Cu lb . Male hind tibia simple. 



^ genitalia (Text-figs 114-117). Dorsal margin of valve sclerotized, apex of margin produced 

 towards uncus and scobinate; dorsal process with a broad, setose projection from basal fourth; 

 hair-scales of coremata light buff. Aedeagus with a strongly sclerotized, acicular projection 

 arising at two-thirds, varying in length geographically. Fulcrum weakly sclerotized and 

 simple, not extending to tip of aedeagus. Vesica with a thorn-like cornutus, two-fifths as 

 long as greatest width of aedeagus. 



§ genitalia (PI. 26, figs 553-556). Sterigma with a digitate process extending anteriorly, 

 the extent varying geographically. Posterior third of corpus bursae sclerotized. 



Measurements. Fore wing: <$ 12-15 mm; ? 13-16 mm. Antennal pectinations: $ 11 X, 

 $ 6 X diameter of shaft. 



Distribution. C. & W. Africa, Ethiopia, Tanzania, Madagascar. 



Three subspecies are recognized, characterized by the structure of the aedeagus. 



Zamarada excavata excavata Bethune-Baker 

 (Text-figs 114, 115; PI. 26, figs 553, 554; PI. 102, fig. 913) 



Zamarada excavata Bethune-Baker, 1913 : 573. Holotype J, Angola (BMNH) [examined]. 

 Zamarada excavata Bethune-Baker; Fletcher, 1958a : 142. 



Distinguished by the length of the acicular projection arising at two-thirds aedeagus, which 

 is 1-75 times as long as the greatest width of the aedeagus. 



The underside of the non-hyaline area of the fore wing is greyish brown, except for a pale 

 greyish orange apical patch; the non-hyaline area of the hind wing is greyish orange, the 

 proximal half suffused with greyish brown between apex and vein M 3 . 



Distribution. Angola, Cameroun, Nigeria, Guinea, Central African Republic, 

 Zaire, Uganda, W. Kenya, Tanzania, Zambia, Malawi.
