Measurements. Fore wing: <$ 12 mm; 2 13 mm. Antennal pectinations: q 9 x, $ 4 X 

 diameter of shaft. 



Closely similar in colour and pattern to subintemipta Gaede in the excavata- 

 group. Differs in the slightly greater extension of the hyaline area towards the 

 tornus on the fore wing and towards the anal angle on the hind wing and in the 

 uniformly brown non-hyaline terminal area on the underside of each wing; differs 

 further from subintemipta in the male in having a simple, non-dilate hind tibia. 

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

 complex sterigma are diagnostic. 



Distribution. Angola, Zaire.

Zamarada urania Oberthur 

 (Text-figs 191, 192; PI. 39, figs 607, 608; PL 107, fig. 964) 



Zamarada urania Oberthur, 1912 : 259, 350, pi. 152, fig. 1465. Holotype $, Cameroun 

 (BMNH) [examined]. 



$ 2 (PI- 107, fig. 964). Hyaline area of wings yellowish grey slenderly edged distally with 

 black; discal spots dark grey, large on fore wing. Non-hyaline terminal area of each wing 

 purplish grey irrorate with dark grey distad of the subterminal fascia, which is brown edged 

 distally with light yellow and broken into irregular interneural spots: cilia chequered light 

 yellow and dark grey. Underside of non-hyaline terminal area of wings uniformly brownish 

 grey; cilia as upperside. 



The hind tibia in the male has a tuft of short hair-scales, equal in length to width of tibia, 

 probably best discernible in slide-mounted specimens. 



$ genitalia (Text-figs 191, 192). Apex of valve tapered and inclined towards uncus, 

 apical area triangular in shape; hair-scales of coremata black. Apex of aedeagus slightly 

 sinuous and tapered with a short, digitate projection at three-fourths. Fulcrum sinuous, 

 dilate apicad with two angular projections from just below apex. Vesica with a scobinate, 

 tapered cornutus. 



$ genitalia (PI. 39, figs 607, 608). 



Measurements. Fore wing: <-£ 12-5 mm; 2 12 mm. Antennal pectinations: $ 9 X , 2 1*5 X 

 diameter of shaft 



Distinguished externally from other species in the protrusa-group by the shallow 

 intrusion of hyaline into the non-hyaline terminal area of each wing and by the 

 large discal spot on the fore wing. In the male genitalia the form of the valve 

 and the presence of a scobinate cornutus and in the female the form of the very 

 small and simple sterigma and the extent of the sclerotization of the corpus bursae 

 are diagnostic. 



Distribution. Cameroun, Gabon.
