REVISION OF GENUS ZAMARADA 37 



sclerotized pattern of the seventh sternum, the very small, simple ostium bursae 

 and the form of the sclerotized posterior half of the corpus bursae in the female 

 genitalia are diagnostic.

Zamarada mesotaenia Prout stat. n. 



(Text-figs 33, 34; PI. 7, figs 477, 478; PI. 96, fig. 856) 



Zamarada consecuta mesotaenia Prout, 1931 : 272. Holotype <$, Somalia (BMNH) [examined]. 



<$ $ (PI. 96, fig. 856). Hyaline area of each wing irrorate with black and finely edged distally 

 with the sharply marked, black postmedial fascia; discal spots large, that on fore wing grey 

 ringed with black, that on hind wing black and ovate; antemedial fascia on fore wing black, 

 medial fascia on each wing usually broad and black, sometimes ill-defined. Non-hyaline 

 terminal third of each wing light brown densely irrorate with black; subterminal fascia 

 dentate, broken and black, edged distally with a few scattered white scales. 



3* genitalia (Text-figs 33, 34). Uncus strongly sclerotized; apical half one-fourth width 

 of basal half and tapered, dorsal and ventral surfaces compressed to form chisel-like tip. 

 Ventral plate of gnathus almost triangular. Valve simple, broadly rounded at apex; dorsal 

 process with a weakly sclerotized, spatulate projection at three-fourths. Fulcrum extending 

 beyond aedeagus, apex broadened and coarsely scobinate; aedeagus tapered apicad, with 

 thorn-like projection at one side near apex. Vesica with a cluster of short spines. 



$ genitalia (PI. 7, figs 477, 478). Lamella postvaginalis broadly rounded posteriorly. 

 Posterior third of corpus bursae sclerotized and ribbed; signum stellate. 



Measurements. Fore wing: q 12-15 mm; $ I 3"5 _I 5'5 mm. Antennal pectinations: 

 6* 12 X, $ 3 x diameter of shaft. 



Externally closely similar to, but a little darker than the preceding species, 

 labrys. Structurally the form of the uncus, the well developed, almost triangular 

 ventral plate of the gnathus, the form of the dorsal process of the valve and of the 

 aedeagus and fulcrum in the male genitalia and the broadly rounded lamella post- 

 vaginalis in the female genitalia are diagnostic. 



Distribution. Somalia, Kenya.
