Zamarada merga sp. n. 



(Text-figs 366, 367; PL 117, fig. 1054) 



q (PI. 117, fig. 1054). Externally closely similar in colour and pattern to subincoloris, from 

 which it may be distinguished by the colour of the underside of the non-hyaline terminal area 

 of the wings, which is brownish orange, only the terminal half of the fore wing being suffused 

 with brownish grey. 



$ genitalia (Text-figs 366, 367). These, which suggest a closer affinity with rupta, are 

 diagnostic in the form of the bifurcate valve. Uncus evenly tapered to narrowly rounded tip. 

 Ventral plate of gnathus tapered, as illustrated, the perimeter minutely scobinate. Valve 

 deeply bifurcate at apex, ventral and dorsal arms longer than width of valve at point of cleavage ; 

 ventral arm produced to a stout, fine point, dorsal arm irregularly margined and tapered to 

 a thorn-like tip, which is inclined towards the uncus. Aedeagus tapered and blade-like with 

 a minute, thorn-like projection at one-half. Apical fourth of fulcrum scobinate. 



$ unknown. 



Measurements. Fore wing: <J 17 mm. Antennal pectinations: (J8 X diameter of shaft. 



Distribution. Gabon. 



Holotype <$, Gabon: Belinga, Camp Central, 500 m, 25.iii.1963 (G. Bemardi),

Zamarada lima sp. n. 



(Text-figs 368, 369; PL 76, figs 757, 758; PL 117, fig. 1051) 



^9 (PI- JI 7> n §- I °5 1 )- Hyaline area of wings weakly tinged with green, varyingly striate 

 with brownish grey and finely edged distally with dark brown; brownish grey striation with 

 purplish tinge in oblique light; costa of fore wing orange-yellow densely striate with silvery 

 grey, except for two spots in basal half; discocellulars silvery grey, slenderly marked on hind 

 wing, ovate on fore wing. Non-hyaline terminal area of each wing uniformly brownish grey 

 (pi. 5, D2), or a shade darker; dentate subterminal fascia brownish yellow, dentations dark 

 brown distally, fascia edged distally with glossy buff; cilia chequered greyish yellow and 

 brownish grey. Underside of non-hyaline terminal area and discal spot on fore wing greyish 

 brown, anal angle of hind wing often paler. 



£ genitalia (Text-figs 368, 369). Uncus tapered to notched tip with a short blunt projection 

 inclined ventrad; apical margin one-half as wide as base. Apical margin of ventral plate 

 of gnathus narrowly rounded. Valve incurved towards uncus apicad, apex finely tapered 

 and scobinate; a very short, digitate projection from ventral margin at point of curve. 

 Fulcrum of even width from base to apex. 



$ genitalia (PL 76, figs 757, 758). Lamellae slender and scobinate; posterior margin of 

 each notched medially. Corpus bursae sclerotized posteriorly. 



Measurements. Fore wing: £ 14-19 mm; $ i5'0-i7-jmm. Antennal pectinations: 

 J i2'5 X, 5 3 X diameter of shaft. 



Distinguished externally by the uniformly coloured non-hyaline terminal area 

 and the brightly coloured and well contrasted subterminal fascia; small examples 

 might be confused with euerces in the metrioscaphes-group by reason of the large, 

 pale grey discal spot on the fore wing, but the male of euerces may be distinguished 

 by the simple hind tibia. In the male genitalia the form of the tapered, scobinate 

 valve and the even width of the fulcrum and in the female the form of the 

 scobinate lamellae are diagnostic.
