Genus ZIZULA Chapman 



Zizula Chapman, 1910 : 483 ; Pinhey, 1949 : 121 ; Swanepoel, 1958 : 74. Type-species : 



Papilio hylax Fabricius = Lycaena gaika Trimen, by original designation. 

 Cupido Schrank (partim) ; Aurivillius, 1898 : 378 ; 1925 : 495. 

 Lycaena Fabricius (partim) ; Murray, 1935 : l & 2 - 



Eyes smooth ; palpi long, strongly ascending, second segment laterally compressed, clothed 

 with scales and below with long stiff hair, third segment long, slender, acuminate ; antennae 

 white-annulated, about two-thirds the length of the costa, club ovoid, well differentiated ; 

 thorax clothed below with long white silky hair ; abdomen long, extending well beyond the 

 anal angle of the hind wing ; o* f° re leg. tibia longer than the femur, tarsus short, unsegmented, 

 strongly spinose below. 



Wing shape. Fore wing subtriangular, elongate, costa evenly convex, apex rounded, outer 

 margin convex, hind wing oval, elongate, no tail. 



Wing venation (Text-fig. 346). Fore wing with 11 veins ; 11 reduced to a short cross-vein 

 between the upper edge of the cell and 12. 



Male genitalia (Text-fig. 226) (see also Chapman, Trans, ent. Soc. Lond. 43 : 493, pi. 59, figs. 33 ; 

 and 35) : uncus bifid, reminiscent of the Plebeiinae, the two lobes with rounded apices ; 

 subunci curved, robust, apex blunt, not hooked, tegumen large, vinculum narrow ; lower 

 fultura composed of a simple narrow blade, bent at right angles, bifid at its tip (in the mount 

 from which the drawing was made the fultura had adhered to the penis) ; valves reduced, the 

 upper process, which is folded over the lower one strongly sclerotized and ending in a long, 

 curved digitate process crowned with a bundle of small spines, the lower process weakly sclerot- 

 ized, and with a rounded apex ; at the apex of the anterior edge of the valve there is an enormous 

 long and rigid bristle, probably composed of an agglomeration of hairs because, under high 

 magnification, it seems longitudinally channelled, and is wide at its apex, which is irregularly 

 truncate ; besides this large bristle there are 6 to 8 others, more slender and less rigid, but 

 nearly equal in length (for the sake of the clarity only the points of insertion of these bristles 

 are shown in the figure) ; penis short, massive, ending in two long beak-like points, the upper 

 one with a smooth outer edge, and a grooved inner edge, the lower one with a slightly serrated 

 outer edge ; in situ the lower part lies in the groove of the upper part which, at its base, has on 

 each side a small rugose triangular excrescence ; uncal lobes and distal portion of the lower 

 process of the valves pilose.
