Zamarada townsendi sp. n. 



(Text-figs 19, 20; PL 4, figs 465, 466; PI. 96, figs 849-851) 

 [Zamarada phaeozona Hampson sensu Fletcher, 1958 : 141. Misidentification.] 



tj $ (PI. 96, figs 849-851). Hyaline area of wings varyingly, but usually lightly, irrorate 

 with brownish yellow, the irroration often concentrated medially to form an ill-defined medial 

 fascia. Basal area of each wing, edged distally with a dark antemedial fascia, and non-hyaline 

 terminal third, edged proximally with a fine, black postmedial fascia, brownish orange 

 (pi. 5, C6, Pompeian yellow) to yellowish brown (pi. 5, D5, clay); subterminal fascia glossy 

 buff, edged proximally with black, usually marked in costal, discal and tornal areas of fore 

 wing, but often wanting. In a few examples the area between the postmedial and subterminal 

 fasciae is uniformly black. 



(J genitalia (Text-figs 19,20). Uncus tapered to narrowly rounded tip; base with long 

 setae dorsally. Ventral plate of gnathus diamond-shaped, minutely scobinate. Valve 

 simple, apex slightly tapered; dorsal process with acicular projection at five-sevenths. 

 Fulcrum eight-ninths as long as aedeagus, apex broad and spatulate; aedeagus slenderly 

 sclerotized and serrate at one side in apical half. Vesica with a cluster of 12-15 spines. 



$ genitalia (PI. 4, figs 465, 466). Ostium bursae asymmetrical, posterior margin incised 

 medially. Ductus seminalis broadly spiral. Corpus bursae sclerotized and ribbed posteriorly; 

 signum almost semi-circular, the edges only minutely and sparsely serrate. 



Measurements. Fore wing: <§ io-o-i3'5 mm; $ 9-13 mm. Antennal pectinations: ^ 14 X, 

 $ 3 X diameter of shaft. 



Most examples are distinguishable externally from minimaria and from latilimbata 

 by the brownish yellow to yellowish brown colour of the non-hyaline terminal 

 third of each wing. In the male genitalia the form of the ventral plate of the 

 gnathus and of the aedeagus and in the female the form of the ostium bursae, the 

 ductus seminalis and the sclerotization of the corpus bursae are diagnostic. 



The species is named in honour of the late A. L. H. Townsend of Nakuru, who 

 successfully reared this and very many other species of Kenyan Lepidoptera. 



Distribution. Kenya, Uganda.
