Zamarada oxybeles sp. n. 



(Text-figs 155, 156; PL 32, figs 579, 580; PL 105, fig. 937) 



^ § (PI. 105, fig. 937). Hyaline area of wings greyish yellow (pi. 3, B4, straw-yellow). 

 Non-hyaline terminal area of wings brownish orange (pi. 6, C5, Sahara) to greyish brown 

 (pi. 5, E3, mouse-grey) ; subterminal fascia brownish orange, dentate and curved proximad 

 between costa and vein RI 3 on fore wing. Underside of non-hyaline terminal area uniformly 

 dark brown. 



Hind tibia in male simple. 



(J genitalia (Text-figs 155, 156). Apical half of uncus of even width to rounded tip. 

 Valve finely tapered, tip acicular; dorsal margin sclerotized; dorsal process dilate and setose 

 at one-fourth; hair-scales of coremata light buff. Aedeagus with rounded apex; a blunt, 

 spatulate projection, smooth-edged or shortly spined at one side, is situate at two-thirds. 

 Fulcrum tapered to acicular tip, without lateral projections. Vesica with a stout, tapered 

 cornutus. 



$ genitalia (PI. 32, figs 579, 580). 



Measurements. Fore wing: <$ O- 13-14 mm. Antennal pectinations: j 1 n x, $ 5 X 

 diameter of shaft. 



Distinguished from the externally similar calypso Prout and viettei sp. n. by the 

 distinct proximad curve of the subterminal fascia between the costa and vein M 3 

 on the fore wing; in the other two species the subterminal fascia is straight on the 

 anterior half of the fore wing; distinguished further b} r the rather deeper and 

 smoother -margined intrusion of the hyaline area into the patterned terminal area 

 of each wing and from viettei by the uniformly greyish brown colour of the underside 

 of the non-hyaline terminal area of the wings. In the male genitalia the finely 

 tapered valve with its straight, acicular tip and in the female genitalia the form 

 of the sterigma are diagnostic. 



Distribution. Central and eastern Madagascar.
