Epicampoptera ivoirensis sp. n. 



(Text-figs. 27-30 ; Map 1) 



Diagnosis. q\ $. I can find no significant external differences between this species and 

 andersoni. The degree and type of individual variation in coloration is the same in both species. 



o* genitalia (Text-figs. 28-30) : saccus moderately globose ; eighth sternum subject to 

 small variations in length of arms, but apparently invariably contorted as in Text-fig. 29 ; 

 apodemes directed posterolaterally. 



$ genitalia (Text-fig. 27) : ostial and post-ostial segment strongly sclerotized ; posterior 

 apophyses very short ; anterior apophyses long ; ostium broad, not shielded ventrally by 

 processes of ostial segment ; signum simple. 



Measurements. A.P.R. : $. 20 ; 9- I 5- Wing : <$. 20-5, 17-0-21 o mm. (15) ; $. 

 22-0, 19-5-22-5 mm. (5). 



Discussion. As suggested on page 24, this species is possibly most closely 

 related to difficilis, known only from Fernando Po, and may replace it on this part 

 of the mainland of Africa, the two species forming a single superspecies. However, 

 until a second male of difficilis is available, with complete genitalia, it is not possible 

 to confirm this. 



Distinguished from difficilis, and from andersoni and tamsi, by the male and 

 female genitalia. 



Distribution (Map 1). Ghana, Ivory Coast and Guinea.
