Zamarada phaeozona Hampson 

 (Text-figs 29, 30; PL 6, figs 473, 474; PI. 95, fig. 848) 



Zamarada phaeozona Hampson, 1909 : 123, pi. 4, iig. 51. Holotype <J, Uganda (BMNH) 

 [examined]. 



$ $ (PI. 95, fig. 848). Hyaline area of each wing irrorate with brownish yellow, grey and 

 black; antemedial fascia and ill-defined medial fascia, when present, grey. Non-hyaline 

 terminal third of each wing brownish yellow to light brown, densely irrorate with silvery 

 grey and dark grey; postmedial fascia black; broken, dentate subterminal fascia dark grey to 

 black, finely edged distally with a glossy, light buff. 



O* genitalia (Text-figs 29, 30). Uncus short and bluntly tipped; base with long setae 

 dorsally. Ventral plate of gnathus minutely scobinate with a small U-shaped depression 

 medially. Valve simple, apex narrowly rounded; a weak, setose, longitudinal ridge, parallel 

 with dorsal margin, is developed in a few examples; dorsal process simple, slightly dilate and 

 curved at two-thirds. Fulcrum equal in length to aedeagus, apical third finely and densely 

 scobinate, the longest spines at apex; aedeagus narrowly rounded at apex, a band of spines 

 situate at one side from two-thirds to five-sixths of its length. Vesica with a cluster of 

 short spines. 



$ genitalia (PI. 6, figs 473, 474). Posterior margins of lamellae sometimes irregularly 

 crenulate, as in figure (PI. 6, fig. 474), sometimes smooth. Corpus bursas sclerotized posteriorly, 

 as figured; signum discoid, the perimeter shortly serrate. 



Measurements. Fore wing: 8-5-ii-5mm; $ 9-12 mm. Antennal pectinations: $ 11 X, 

 $ 2 x diameter of shaft. 



Externally closely similar to anacantha; distinguished structurally by the form 

 of the gnathus, by the simple, curved dorsal process of the valve, by the form of 

 the fulcrum and of the aedeagus in the male genitalia and by the form of the sterigma 

 and the extent of the sclerotization of the corpus bursae in the female genitalia. 



The degree and extent of the spining of the fulcrum shows some variation; in 

 examples from Mozambique, Angola and South West Africa there is a cluster of 

 longer spines at five-eighths of its length that are comparable in size with the apical 

 cluster. 



The short series of five males and three females from Dire Daoua in Ethiopia, 

 a male from Kibwezi in Kenya, two males and a female from Amani in Tanzania 

 and a male and female from Quirimbo in Angola differ from the remainder of the 

 material available for study in their smaller size (fore wing 8-5-9-0 mm) and paler 

 colour. 



Distribution. Ethiopia, Uganda, Kenya, Tanzania, Mozambique, Transvaal, 

 Angola, South West Africa.
