REVISION OF GENUS ZAMARADA 157 



terminal area of the hind wing, which is not suffused with dark brown; distinguished 

 from vulpina and from longidens by the evenly marked subterminal fascia, which 

 is not broadened between the costa and vein M x on the fore wing. Distinguished 

 structurally from all three species by the form of the dorsal process of the valve 

 and by the ornamentation of the vesica in the male genitalia and by the form 

 of the corpus bursae and the pattern of its sclerotization in the female genitalia. 



Distribution. Tanzania, Amani.

 no. 7338, in BMNH. 



Paratypes. Tanzania: Amani (G. Pringle), 1 <$, 1 $ (BMNH); Amani xi. 1965

Zamarada candelabra flexura subsp. n. 



(PI. in, figs 995) 



Distinguished from the nominate subspecies by the smoother, less crenulate distal margin 

 of the hyaline area and by the paler colour and the usually narrower non-hyaline terminal 

 area of each wing; the intrusion of the hyaline into this area, between veins M 3 and Cw lb , 

 is shallower and evenly rounded distally. The ratio of non-hyaline to hyaline areas is 0-7:2.

Zamarada exigua sp. n. 



(Text-figs 263, 264; PI. 55, figs 672, 673; PI. Ill, fig. 996) 



cJ$ (PI. in, fig- 996). Hyaline area of wings tinged with green, finely edged distally with 

 dark grey and sparsely striate with dark grey; discal spots grey. Non-hyaline terminal area 

 of each wing light buff irrorate with light grey; subterminal fascia dark grey, dentate distad, 

 diffuse proximad; cilia chequered light buff and grey. Underside of non-hyaline terminal 

 area: fore wing grey, dark and intense anterior of vein M z and at tornus; hind wing buff suffused 

 with dark grey anterior of vein M 3 . 



O* genitalia (Text-figs 263, 264). Ventral plate of gnathus narrowly rounded and minutely 

 scobinate. Juxta slender and of even width. Valve similar to that of candelabra, but basal 

 two-thirds of dorsal process slender, straight and of even width; projection at two-thirds 

 longer than in that species. Apical twelfth of aedeagus slender and rod-like with rounded 

 tip. Apical cornutus scobinate ; basal transverse cornutus one-half as long as width of aedeagus. 



$ genitalia (PL 55. figs 672, 673). Posterior half of corpus bursae narrowed, posterior 

 third sclerotized, more strongly than in candelabra. Lamella antevaginalis sclerotized, 

 broadly rounded anteriorly, narrowed posteriorly.
