Holotype <$, Gabon: Belinga, 900 m, Grand Crete Sud, 19.iii.1963 (G. Bernardi), 

 in MBG, Paris. 



The VIETTEI-Groxjp 



In habitus closely similar to many species in the excavata and protrusa-groups. 



In the male genitalia the uncus is short, tapered and dorsally setose. Ventral 

 plate of gnathus well developed and smooth, apex narrowly rounded. Valve 

 weakly sclerotized, more strongly along ventral margin; dorsal process with large, 

 setose projection at one-third. Aedeagus rounded at apex; an apically rounded, 

 spatulate projection at four-fifths. Fulcrum strongly sclerotized, apex broadly 

 asymmetrical and coarsely spined, a large spine at the right side. Vesica with 

 a sinuous cornutus. 



Zamarada viettei sp. n. 



(Text-figs 207, 208; PI. 42, figs 619, 620; PI. 100, fig. 899) 

 [Comibaena reflexaria Walker sensu Saalmuller, 1891 : 495, pi. 14, fig. 265. Misidentification.] 



<$ Q (PI. 100, fig. 899). Hyaline area of wings weakly tinged with greyish yellow, sparsely 

 striate with grey that is vinaceous tinged in oblique light, and finely edged distally with brown; 

 discal spots minute, jet-black. Non-hyaline terminal area greyish orange (pi. 5, B4) suffused 

 with brownish grey (pi. 6, C2) proximad of the subterminal fascia, sometimes over the entire 

 area in the female, the suffusion having a vinaceous tinge in oblique light; dentate subterminal 

 fascia light brown (pi. 6, D6, cinnamon) finely edged distally with glossy buff, first tooth- 

 mark on fore wing mixed with black; cilia chequered greyish yellow and grey. Underside of 

 non-hyaline terminal area greyish orange suffused with dark grey in discal area of fore wing, 

 sometimes densely over whole area in female. 



Male hind tibia dilate with a tuft of hair-scales one-third as long as tibia. 



$ genitalia (Text-figs 207, 208). Described under species-group heading. 



§ genitalia (PI. 42, figs 619, 620). Posterior margin of lamella antevaginalis irregularly 

 dentate, but with smoothly edged medial excavation. Posterior margin of lamella postvaginalis 

 irregularly crenulate. Corpus bursae very weakly sclerotized posteriorly and scobinate medially 

 just anterior of operculum. 



Measurements. Fore wing: ^ 12-13 mm; § n-o— 11 -5 mm. Antennal pectinations: 

 6* 15 X, $ 7 X diameter of shaft. 



Distinguished externally from similarly patterned oxybeles in the excavata-gvonp 

 and calypso in the polydemon-group occurring in Madagascar by the almost 

 colourless hyaline area of the wings and the smaller, smooth-edged excavations 

 of the non-hyaline terminal area between veins M 3 and Cu lh on each wing. The 

 male is further distinguished by the presence of a dilate, tufted hind tibia and 

 by its longer antennal pectinations. 



Distribution. Madagascar.
