Zamarada jansei sp. n. 



(Text-figs 77, 78,; PI. 18, figs 521, 522; PI. 99, fig. 890) 

 [Zamarada differens Bastelberger sensu Janse, 1932 : 141 (part), text-fig. 39. Misidentification.] 



(J$ (PI. 99, fig. 890). Costa of fore wing yellowish brown to brownish orange, irrorate with 

 black; posterior margin of fore wing and non-hyaline terminal third of each wing light brown 

 (pi. 5, D6) irrorate with black; densely in subterminal area; ante- and postmedial fasciae 

 slender and black; discal spots black; hyaline area, intruding very slightly into patterned 

 distal third between veins M 3 and Cu lb , irrorate with black or with light brown and black. 



(J genitalia (Text-figs 77, 78). Uncus tapered. Ventral plate of gnathus not developed. 

 Dorsal process of valve halberd-shaped with a scobinate-edged, blade-like projection between 

 one-half and three-fourths. Aedeagus with two tapered, apical processes, the longer one 

 scobinate. Vesica with a cluster of short spines. 



9 genitalia (PI. 18, figs 521, 522). Posterior third of corpus bursae ribbed and sclerotized. 

 Signum stellate. 



Measurements. Fore wing: $ 12mm; $ 13mm. Antennal pectinations: J 12 X, $ 

 4 X diameter of shaft. 



Differs externally from differens in the darker, black irroration of both hyaline 

 and non-hyaline areas of the wings and in the usually better developed black 

 antemedial fascia, which extends to the costa on the fore wing. In the male genitalia 

 the tapered uncus, the halberd-shaped dorsal process of the valve and the presence 

 of cornuti on the vesica and in the female genitalia the sclerotization and ribbing 

 of the posterior third of the corpus bursae are diagnostic.

The SCRIPTI FASCIA TA -Group 



All the species in the group are Oriental in distribution. The hyaline area of the 

 wings is greyish yellow with little or no dark irroration; the non-hyaline terminal 

 area is predominantly brown or greyish brown; the fore wing measures 13-18 mm. 

 The group is characterized in the male genitalia by the cowl-like uncus, which has a 

 minute, tapered projection from the mid-apical margin, a slender dorsal ridge and 

 long setae on the dorsal surface basad. The ventral plate of the gnathus is usually 

 tapered to a narrowly rounded tip. The aedeagus has one or two longitudinal, 

 scobinate ridges. The fulcrum is reduced, slender and weakly sclerotized. Vesica 

 with a stout cornutus. The female genitalia have three processes extending 

 posteriorly from the sterigma, a medial process from the lamella postvaginalis and 

 two lateral processes, serrate at apices, from the lamella ante vaginalis.
