REVISION OF GENUS ZAMARADA 167 



Zamarada euphrosyne Oberthiir 

 (Text-figs 277, 278; PL 58, figs 684, 685; PL 112, fig. 1017) 



Zamarada euphrosyne Oberthiir, 1912 : 260, 350, pi. 152, figs 1467, 1468. LECTOTYPE 



<$, Cameroun (BMNH), here designated [examined]. 

 Zamarada euphrosyne Oberthiir; Gaede, 1915 : 116. 

 Zamarada euphrosyne Oberthiir; Herbulot, 1954 : 326. 



^ $ (PI. 112, fig. 1017). Hyaline area of wings tinged with greyish yellow and sparsely 

 irrorate with reddish grey; discal spots dark grey. Basal and non-hyaline terminal areas of 

 each wing reddish grey (pi. 12, D2) irrorate with black; dentate subterminal fascia light brown 

 edged distally with black; cilia chequered reddish grey and greyish yellow, the greyish yellow 

 extending proximad to reach hyaline area of each wing between veins M % and Cu lb . Underside 

 of non-hyaline terminal area brownish grey; cilia chequered brownish grey and greyish yellow, 

 the latter colour suffusing proximad as on upperside. 



$ genitalia (Text-figs 277, 278). Ventral plate of gnathus broad, minutely scobinate medially. 

 Juxta very slender. Dorsal process of valve with setose projection at one-third. Aedeagus 

 short and stout with an apically rounded, blade-like projection in apical fourth. Fulcrum 

 broad and short, arising at one-half of aedeagus. 



$ genitalia (PI. 58, figs 684, 685). Lamella postvaginalis tapered and narrowly rounded 

 posteriorly. Basal part of ductus seminalis dilate, similar to that of dilucida, partially coiled 

 and minutely scobinate. 



Measurements. Fore wing: J 9-11 mm; $ 8*5-1 i*omin. Antennal pectinations: <$ 15 X, 

 $ 6 X diameter of shaft. 



In pattern and colour, especially in the extension of the greyish yellow suffusion 

 of the non-hyaline terminal area between veins M 3 and Cu lh on each wing, 

 reminiscent of aglae; distinguished by its smaller size and appreciably longer 

 antennal pectinations in both sexes. Structurally the form of the valves, with 

 the transverse band of long setae on the dorsal surface of the left valve, and of 

 the aedeagus with the short, broad fulcrum and the dense cluster of short, slender 

 spines on the vesica in the male genitalia and the form of the sterigma and of the 

 dilate and scobinate ductus seminalis in the female genitalia are diagnostic. 



Distribution. Equatorial Africa.
