REVISION OF GENUS ZAMARADA 69 



[Zamarada translucida Moore sensu Moore, 1887 : 432. Misidentification.] 



[Zamarada translucida Moore sensu Singh, 1953 : 107, figs 3, 74 (larvae). Misidentification.] 



$ genitalia (Text-figs 87, 88). Ventral plate of gnathus truncate and minutely scobinate. 

 Apex of valve spatula te and narrowly rounded; dorsal process of valve dilate and setose at 

 one-third and angled through 90 degrees at two-thirds, the apex finely tapered. Aedeagus 

 with coarse, thorn-like projections at one side in apical fourth. Vesica with a stout, tapered 

 cornutus. 



$ genitalia (PI. 20, figs 531, 532). Sterigraa with three processes extending posteriorly; 

 medial process rounded at tip and subequal in length to the two lateral, serrate-tipped processes. 

 Posterior third of corpus bursae weakly ribbed and strongly sclerotized at one side; remainder 

 membranous with a stellate signum. 



Measurements. Fore wing: £ 16-18 mm; $ 15-18 mm. Antennal pectinations: <$ 12 

 $ 9 X diameter of shaft. 



Externally similar to scriptifasciata and to baliata, differing in its larger size, in 

 the rather paler and clearer hyaline area of each wing and its deeper, smooth-edged 

 penetration of the terminal third between veins M 3 and Cu lh (PI. 100, figs 897, 898). 

 Structurally the form of the valve and of the aedeagus in the male genitalia and the 

 degree of sclcrotization of the corpus bursae in the female genitalia are diagnostic. 



Biology. Singh (1953: 107) gives a detailed description of the larva under the 

 name Zamarada translucida Moore, which he records as a defoliator of Cassia fistula 

 Linnaeus (Leguminosae) in India. 



Distribution. Burma, India, Ceylon.
