 Zamarada terpsichore Oberthiir; Prout, 1915 : 343. [Err. synonymy.] 



<J genitalia (Text-figs 392-394). Closely similar to those of perlepidata, differing in the 

 form of the asymmetrical valves. In perlepidata the apical margin of the left valve is very 

 shallowly excavate between the spined tip of the ventral margin and the bluntly produced 

 tip of the dorsal margin. In terpsichore the apical margin of the left valve is straight or arched 

 between the spined tips of the ventral and dorsal margins. Vesica without cornutus. 



$ genitalia (PI. 82, figs 781, 784, 785). Closely similar to those of perlepidata, differing in 

 the less extensive leftward lateral extension from the operculum of the sclerotized, asymmetrical 

 lamella antevaginalis 



Colour of upper and under surfaces of wings similar to those of perlepidata. Three 

 subspecies are recognized, differing in size and pattern; each differs from perlepidata, none 

 having the almost straight distal margin of the white, hyaline area of the fore wing, characteristic 

 of that species. 



The male hind leg is similar to that of perlepidata. 



Measurements. Fore wing: <$ 15-17 mm; $ 14-17 mm. Antennal pectinations: <$ $, 5 X 

 diameter of shaft. 



Distribution (Map 5). Nigeria, Cameroun, Angola, Zaire, Uganda.
