REVISION OF GENUS ZAMARADA 83 



Zamarada pringlei sp. n. 



(Text-figs 108, 109; PL 25, figs 549, 550; PL 102, fig. 911) 



^ ^ (PI- io2 ' fig- 9 11 )- Head and vertex greyish yellow (pi. 4, B5, corn-colour); thorax and 

 dorsum orange-grey (pi. 5, B2), the latter with a medial white spot on the first and a pale 

 medial spot on each of the remaining segments. Hyaline area of each wing greyish yellow 

 (pi. 2, B5) very finely edged distally with yellow, then with dark brown; costa and posterior 

 margin of fore wing and posterior margin of hind wing orange-grey irrorate with brownish 

 orange and black; discal spots black. Non-hyaline terminal area of each wing orange-grey 

 edged proximally with a slender, darker band of brownish grey (pi. 7, C2) ; subterminal fascia 

 a darker shade of brownish grey, dentate in discal area, slender between veins M 3 and Cu lb ; 

 termen very slenderly black. Underside of non-hyaline terminal area of wings dark brown, 

 except for pale greyish orange patches at apex of fore wing and at anal angle of hind wing; 

 each wing slenderly pale along termen between veins M 3 and Cu lb . Male hind tibia simple. 



^ genitalia (Text-figs 108, 109). Valve truncate; dorsal margin sclerotized, apex produced, 

 inclined towards uncus and scobinate; dorsal process with blunt, setose projection near base; 

 coremata hairs light buff. Aedeagus acutely tapered apicad with two strongly sclerotized, 

 acicular projections at two-thirds, one equal to, one subequal to greatest width of aedeagus. 

 Fulcrum with a pair of angular projections at two-thirds, the apex not extending beyond 

 tip of aedeagus. Vesica with a small, thorn-like cornutus. 



9 genitalia (PI. 25, figs 549, 550). Sterigma with two digitate projections extending anteriorly, 

 one at each side. Posterior half of corpus bursae strongly sclerotized, minutely scobinate 

 at one side. 



Measurements. Fore wing: $ 16 mm; $ 15-17 mm. Antennal pectinations: $ 13 x, 

 9 4 X diameter of shaft. 



Distinguished externally from closely related dentata Fletcher and excavata 

 Bethune-Baker by the orange-grey colour of the non-hyaline terminal area of each 

 wing. Distinguished structurally by the form of the valve, aedeagus and the 

 ornamentation of the vesica in the male genitalia and by the form of the sterigma, 

 with the two digitate projections extending anteriorly, and the extent of the 

 sclerotization of the corpus bursae in the female genitalia.
