Zamarada cathetus sp. n. 



(Text-figs 316, 317; PI. 67, figs 718, 719; PI. 114, fig. 1033) 



$ $ (PI. 114, fig. 1033). Proximal two-thirds of each wing thinly scaled, light buff very 

 sparsely irrorate with cinnamon-brown; costa of fore wing and straight postmedial fascia, 

 forming distal margin of thinly scaled proximal area, cinnamon-brown mixed with a darker 

 shade; discal marks very slender, cinnamon-brown. Non-hyaline terminal third of each 

 wing dark buff irrorate with cinnamon-brown. Underside of non-hyaline terminal third of 

 each wing brown, darker proximad towards postmedial fascia, paler terminad; proximal 

 two-thirds of each wing light buff, discocellulars brown. 



g genitalia (Text-figs 316, 317). Uncus stout and tapered. Ventral plate of gnathus 

 minutely scobinate, tip rounded. Valve abruptly narrowed at one-half dorsal margin, then 

 strongly sclerotized to truncate apex, ventral and dorsal apices angular; dorsal process with 

 a slender, digitate, setose projection in basal fourth. Aedeagus dilate medially with two 

 rounded projections, one digitate, one broader and semi-circular. Apex of fulcrum sinuous, 

 dilate and very densely spined. 



9 genitalia (PI. 67, figs 718, 719). Lamella antevaginalis with irregular pattern of thorn- 

 like projections along lateral and posterior margins; posterior margin shallowly excavate. 

 Lamella postvaginalis with series of dense U-shaped folds and a small sclerotized plate medially. 

 Posterior tenth of corpus bursae sclerotized. 



Measurements. Fore wing: $ 15'5-17-omm; Cj 14-16 mm. Antennal pectinations: 

 d9X,$3 X diameter of shaft. 



Strikingly distinct in colour and pattern. Structurally appears most closely 

 related to fumosa, from which it differs in the male in lacking the dilate hind tibia 

 of that species; in the narrower, truncate valve and the more densely spined apex 

 of the fulcrum in the genitalia; in the female genitalia the form of the sterigma is 

 diagnostic.
