Zamarada saburra sp. n. 



(Text-fig. 260; PI. 54, figs 668, 669; PI. no, fig. 992) 



<J§ (PI. no, fig. 992). Hyaline area of wings greyish yellow varyingly irrorate with brownish 

 orange and finely edged distally with light brown then grey; discal spots ovate outlined in 

 light brown, greyish yellow at centre. Non-hyaline terminal area light yellow (pi. 4, A4) 

 irrorate with brownish orange (pi. 6, C6, caramel-brown) to reddish golden (pi. 6, C7); dentate 

 subterminal fascia of similar shades, ill-defined except in apical area of fore wing, where dark 

 irroration is usually less dense; cilia chequered light yellow and reddish golden. Underside 

 of non-hyaline terminal area light yellow; fore wing suffused with light reddish brown, except 

 at apex; hind wing narrowly light reddish brown proximally, remainder sparsely irrorate with 

 the same shade; cilia as on upperside. 



<J genitalia (Text-fig. 260). Closely similar to those of bastelbergeri, differing in the shorter, 

 smooth aedeagus, which lacks the apical thorn-like projection of that species, and in the form 

 of the twin blades of the fulcrum, which are of equal length, each rounded at apex, and extend 

 beyond the tip of the aedeagus. 



§ genitalia (PI. 54, figs 668, 669). Corpus bursae wholly membranous; signum situate in 

 posterior half. 



Measurements. Fore wing: <J 16-18 mm; $ 15-16 mm. Antennal pectinations: (J 17 X, 

 $ 6 x diameter of shaft. 



Reminiscent of rubrifascia Pinhey in the metrioscaphes-group, from which it may 

 be distinguished externally by its larger size and the presence of a pale-centred, 

 ovate discal spot on each fore wing; further, the distribution of the two species 

 is not known to overlap. 



Distribution. Tanzania, Amani.

The CANDELABRA -Group 



Characterized in the male genitalia by the simple valve, broadly rounded at 

 apex, by the form of its dorsal process, which from base to two-thirds is straight 

 or sinuous, but with a short, spatulate, digitate projection at that point and which 

 in its apical third is then arcuate; by the form of the fulcrum, which is asymmetrically 

 dilate and coarsely spined at apex and by the ornamentation of the vesica, which 

 may have one or two scobinate cornuti, one of which is transversely placed at 

 one-third to one-half. The uncus is short, bluntly tipped and dorsally setose. 

 Gnathus with ventral plate developed. 



In the female genitalia the corpus bursae is narrowed posteriorly, sclerotized 

 and scobinate. The lamella antevaginalis consists of a well developed, sclerotized 

 plate, broadened basad. 



Structurally appears to be without close relatives; placed next to the vulpina- 

 group because of similarity of habitus. 



Six species are recognized; three are only poorly represented and are not
