Zamarada exarata (Felder) ; Oberthiir, 1912 : 257. [Tentative synonymy with transvisata 



[sic] Guenee.] 

 Zamarada transvisaria (Guenee); Janse, 1932 : 138, pi. 2, fig. 3, text-fig. 39. 



(J$ (PI. 108, fig. 966). Hyaline area of wings finely edged distally with light brown; discal 

 spots minute, grey to black. Non-hyaline terminal area, deeply excavate between veins 

 M 3 and Cu lb , greyish orange lightly irrorate with brownish orange, except in discal area of 

 fore wing where the irroration is dense. Underside of non-hyaline terminal area similar to 

 that of upperside. 



Variable in colour; in some examples the hyaline area is tinged strongly with green, in 

 others faintly with greyish yellow. The non-hyaline terminal area in some forms is grey, 

 in others varying shades of brown; the dentate subterminal fascia is often marked sharply 

 and edged distally with pale grey. 



£ genitalia (Text-figs 221, 222). Ventral plate of gnathus bifid. Valve tapered apicad, 

 apical fifth slightly spiral; dorsal margin minutely scobinate apicad, ventral margin smooth; 

 a short arcuate ridge at mid-valve. Aedeagus tapered to narrowly rounded apex; a minute, 

 thorn-like projection immediately below tip. Fulcrum extending beyond apex of aedeagus, 

 the tip finely scobinate. 



§ genitalia (PL 45, figs 629, 630). Sterigma consisting of a strongly sclerotized plate shaped 

 as in figure; a smaller plate, parallel in outline with the posterior margin of the sterigma, 

 situate immediately ventrad of the operculum. 



Measurements. Fore wing: ^9 13-17 mm. Antennal pectinations: ^13 X , $ 6 X diameter 

 of shaft. 



Most examples may be distinguished externally, except from amelga, by the 

 deep, smooth-edged excavation of the non-hyaline terminal area on both wings 

 and by the small area of dense, dark irroration on the fore wing between veins 

 M z and Cu lb . Males may be distinguished from amelga by the shorter pectinations 

 of the antennae; so far as is known, the distributions of the two species do not 

 overlap. In the male genitalia the bifid ventral plate of the gnathus and the 

 form of the slightly spiral valve and in the female the form of the sterigma are 

 diagnostic. 



Distribution (Map 3). Rhodesia, Transvaal, Natal, Cape Province.
