REVISION OF GENUS ZAMARADA 207 



A very beautiful and externally distinctive species. Structurally the form of 

 the aedeagus and the short fulcrum in the male genitalia and the form of the 

 lamella antevaginalis and non-stellate signum in the female genitalia are diagnostic. 



Distribution. Nigeria, Cameroun, Gabon, Zaire.

The UNDIMARGINATA-Grovp 



Characterized in the male genitalia by the form of the valve, which is cleft 

 apicad; ventral third very weakly sclerotized and tapered to setose apex; dorsal 

 two-thirds strongly sclerotized and produced in arcuate form, curving towards 

 uncus, the apical margin evenly serrate. Uncus bulbous in shape, dorsal surface 

 densely clothed with short spines, apex produced ventrad. Aedeagus with short, 

 digitate projection mediodorsally. Vesica with two groups of numerous spine-like 

 cornuti. 



In the female genitalia the posterior margin of the lamella antevaginalis is 

 excavate medially; ventrad of it is a sclerotized plate with a minutely serrate 

 posterior margin. Lamella postvaginalis produced medio-posteriorly in form of a 

 sclerotized tube, tapering and weakening to become membranous and retractile. 



In the male the femur is fringed with buff and long, dark grey hair-scales on 

 its lateral surfaces and with short, very broad, light buff scales on its inner surface; 

 tibia dark grey and grossly dilate enclosing a dense tuft of hair-scales.
