REVISION OF GENUS ZAMARADA 253 



Zamarada thalia Oberthur is a primary homonym of the name of a species now 

 included in the excavata-group. Oberthur recognized his error and published 

 tullia as a replacement name. Unnecessary replacement names were subsequently 

 published by both Strand and Gaede, the former proposing tullia, the latter 

 thalysia. 



The species was based on a mixed series. The paralectotype, figured by 

 Oberthur (1912: pi. 153, fig. 1471) represents a species that is described under 

 the name mimesis sp. n. in the eucharis-group.

Zamarada sagitta sp. n. 



(Text-figs 427, 428; PL 89, figs 814, 815; PL 123, fig. 1101) 



^ genitalia (Text-figs 427, 428). Uncus broadly rounded at apex, dorsal surface densely- 

 setose. Ventral plate and arms of gnathus strongly sclerotized, the plate coarsely scobinate. 

 Valves symmetrical; apical fifth scobinate, incurved towards uncus and finely tapered; a 

 short scobinate ridge at three-fourths ventral margin; dorsal process with setose projection 

 near base. Aedeagus with short, smoothly rounded projection at two-thirds. Fulcrum 

 slender and weakly developed, apex scobinate. 



§ genitalia (PI. 89, figs 814, 815). Lamella postvaginalis arrow-headed in form, posteriorly 

 inclined medial point strongly sclerotized, tapering lateral margins scobinate. 



Measurements. Fore wing: £ 13-14 mm; $ n-13 mm. Antennal pectinations: <J 11 x, 

 5 4 X diameter of shaft. 



Externally closely similar to emaciata in colour and pattern; distinguished from 

 it and from the many similarly patterned species in the groups following the 

 reflexaria-group by its shorter wing length (PL 123, fig. 1101). The males are 

 further distinguished from tullia by the sparse, light buff coremata and by the 

 longer antennal pectinations. The male hind tibia is not dilate, but there is a 

 short, sclerotized pocket, little longer than the width of the tibia, near the femoral 

 joint. 



In the male genitalia the form of the valve, aedeagus and fulcrum and in the 

 female the form of the lamella postvaginalis are diagnostic. 



Distribution. Nigeria, Cameroun, Gabon.
