Zamarada bilobata sp. n. 



(Text-figs 355, 356) 



$ genitalia (Text-figs 355, 356). Uncus laterally rounded, apex shallowly bilobate. Ventral 

 plate of gnathus subequal in width to that of uncus; apical margin excavate in U-shaped 

 form to one-third of depth of plate, greatest width of excavation one-half width of plate; 

 apices of lateral margins strongly sclerotized and minutely scobinate. 



O. unknown. 



Measurements. Fore wing: 17-19 mm. Antennal pectinations: q 10 x diameter of 

 shaft. 



Closely similar in colour, pattern and leg structure to platycephala and 

 distinguished only by the genitalia. Most closely related to clavigera ; distinguished 

 from it by the dense tuft of grey rather than buff hair-scales on the hind tibia, 

 by the form of the uncus, by the narrower ventral plate of the gnathus with its 

 shallower, narrower U-shaped excavation and by the longer, acicular extension 

 of the dorsal margin of the valve. 



Distribution. Gabon.

Zamarada bicuspida sp. n. 



(Text-figs 357-359; PI- 75, figs 753- 754; PI- "7. fi g- I0 49) 



(J $ (PI. 117, fig. 1049). Hyaline area of wings yellowish grey sparsely striate with grey, 

 mainly along posterior margins; costa of fore wing buff striate with grey; discocellulars on 

 hind wing slenderly grey, those on fore wing buff, edged proximally with pearl-grey and dark 

 grey. Non-hyaline terminal area light brown (pi. 6, D4) to greyish brown (pi. 6, D3) ; dentate 

 subterminal fascia dark brown to black, finely pale-edged distally; termen of hind wing tinged 

 with greyish orange; cilia chequered greyish orange and dark grey. Underside of non-hyaline 

 terminal area and of discal mark on fore wing dark grey; cilia similar to those of upperside. 



A short series of three males and two females from Fernando Po (all the males and one 

 of the females are from the Moka Plateau) has genitalia similar to those of the type-series, 

 but resembles platycephala in colour and may represent a subspecies; the hyaline area of the 

 wings is more densely striate with grey and the non-hyaline terminal area is grey with a brown 

 subterminal fascia. A male from Santa Isabel on Fernando Po matches the type-series. 



^ genitalia (Text-figs 357-359). Uncus truncate with a short, beak-like point projecting 

 ventrad from mid-apical margin. Ventral plate of gnathus tapered, apex narrowly rounded. 

 Valve shallowly bifurcate, extended angular apices of ventral and dorsal margins shorter 

 than width of valve at point of cleavage. Aedeagus finely tapered. Fulcrum with thorn-like 

 apex.
