REVISION OF GENUS ZAMARADA 235 



fourth. Tip of curved, sclerotized core of fulcrum smoothly acicular; margins of sheath 

 smooth apicad. Vesica without cornutus. 



9 genitalia (PI. 83, figs 786, 787). Lamella antevaginalis asymmetrical, fused with and 

 overlaid by a broad, strongly sclerotized, transverse band (moved aside through about 45 

 degrees in figures to permit view of operculum) ; lamella postvaginalis strongly sclerotized, 

 V-shaped. Posterior fourth of corpus bursae lightly sclerotized. 



Measurements. Fore wing: £ 16 mm; 9 I 5"5~ I 6 , 5 mm. Antennal pectinations: $ 8-5 X, 

 9 4-5 X diameter of shaft. 



Externally similar to West African reflexaria and also to cucharita, with which 

 it occurs; distinguished from the latter in most examples by the larger discal spot 

 on the fore wing and from both species in the male by the shorter tibial tuft. In 

 the male genitalia the form of the tapered valve and of the smoothly acicular, 

 arcuate core of the fulcrum and in the female genitalia the form of the asymmetrical 

 sterigma are diagnostic. 



Distribution. Tanzania.

Zamarada cucharita sp. n. 



(Text-figs 399, 400; PI. 83, figs 788, 789; PI. 120, fig. 1076) 



(J genitalia (Text-figs 399, 400). Juxta shorter than in rhamphis, the sclerotized apices 

 parallel. Valve truncate, ventral corner of apex sclerotized and thinly spatulate. Central 

 sclerotized core of fulcrum arcuate and scobinate apicad; margins of sheath serrate in apical 

 half. 



9 genitalia (PI. 83, figs 788, 789). Sterigma symmetrical. Lamella antevaginalis fused 

 with and overlaid by a broad, transverse, sclerotized band anteriorly; two weakly sclerotized 

 plates, one at each side, extend posteriorly to rounded apices, the apical margins minutely 

 serrate; posterior ventral margin of the operculum with medial point. Lamella postvaginalis 

 membranous. 



Measurements. Fore wing: <J 13-16 mm; 9 14-16 mm. Antennal pectinations: J 8 

 9 5 X diameter of shaft. 



Closely similar in colour and pattern to rhamphis, differing in the rather shorter 

 wing-span and the usually smaller discal spot on the fore wing (PI. 120, fig. 1076); 

 males differ in having a longer tuft of hair-scales enclosed in the dilate hind tibia, 

 the tuft being just subequal in length to the tibia. In the male genitalia the 

 truncate form of the valve, which may usually be seen in the dry state, the form 

 of the juxta and of the fulcrum and in the female genitalia the form of the sterigma 

 are diagnostic. 



Distribution. Kenya, Uganda, Cameroun, Nigeria, Ghana, Ivory Coast, 

 Liberia, Guinea.
