described. Z. prolata sp. n. is tentatively associated with the candelabra-group 

 because of the presence of a transverse, scobinate cornutus on the vesica and 

 the form of the fulcrum. 



Key to Species and Subspecies 



i Apex of valve evenly rounded. Vesica with two scobinate cornuti. Apex 



of fulcrum asymmetrically dilate, apical margin coarsely spined . . 2 



- Valve tapered, apex of dorsal margin incurved towards uncus. Vesica with 



one transverse, scobinate cornutus at two-fifths. Apex of fulcrum 

 asymmetrically dilate; a scobinate, rod-like projection, two-thirds as 

 long as aedeagus, extends posteriorly from one side . . prolata (p. 158) 



2 (1) Basal two-thirds of dorsal process of valve straight and of even width. Apical 



twelfth of aedeagus slender and rod-like with rounded tip. Basal transverse 

 cornutus one-half as long as width of aedeagus . . . exigua (p. 157) 



- Basal two-thirds of dorsal process of valve sinuous and dilate. Apical sixth 



of aedeagus blade-like to tapered tip. Basal transverse cornutus arcuate, 

 equal in length to width of aedeagus ....... 3

Zamarada candelabra sp. n. 



(Text-figs 261, 262; PI. 55, figs 670, 671; PI. in, figs 994, 995) 



$ genitalia (Text-figs 261, 262). Gnathus with slender, scobinate ventral plate. Juxta 

 narrowed medially. Valve simple, apex broadly rounded; basal two-thirds of dorsal process 

 sinuous and dilate. Vesica with two cornuti. 



$ genitalia (PI. 55, figs 670, 671). Posterior third of corpus bursae narrowed and sclerotized 

 with a more strongly sclerotized, scobinate ridge. 



Measurements. Fore wing: £ 12-5-13-0 mm; $ 13 mm. Antennal pectinations: $ 10 X, 

 $ 4 X diameter of shaft. 



Distribution. Tanzania, Uganda, Zaire. 



Two subspecies are recognized, distinguished by the colour and pattern of the 

 wings. 



Zamarada candelabra candelabra subsp. n. 



(PI. in, fig. 994) 



cj 9- Hyaline area of wings tinged with dull yellow (pi. 3, B3), lightly irrorate with brownish 

 grey. Dentate subterminal fascia light yellow (pi. 4, A4) edged proximally with brownish 

 orange (pi. 7, C7); non-hyaline terminal area of each wing brownish grey (pi. 11, D2) proximad 

 of subterminal fascia, light orange (pi. 5, A5) irrorate with brownish grey distad of it; cilia 

 chequered light orange and brownish grey. Ratio of non-hyaline to hyaline area at vein 

 Cu lb on fore wing 1:2. Underside of non-hyaline terminal area of wings brownish orange, 

 apex and tornus of fore wing dark brown. 



Externally similar to bathyscaphes and to vulpina and longidens in the vulpina- 

 group. Distinguished from bathyscaphes by the underside of the non-hyaline
