THYRIDIDAE OF AFRICA AND ITS ISLANDS 125 



Genitalia $ (PI. 60, figs 371, 372). Anal papillae short, rather rounded. Ostium spiny, 

 broad, duct lightly sclerotized, bursa with minute spines. 



Discussion. Externally this species is similar to K. fractifascia but the subapical 

 line of effrenata is straight and continuous, whereas in fractifascia it is usually 

 interrupted and curved. The genitalia of the two species are distinct. K. effrenata 

 is placed in the squamigera-group on pattern but the genitalia of the males are less 

 modified than the others in the group.

Kuja kibala sp. n. 



(PI. 14, fig. 69; PI. 38, fig. 212) 



(J. Wing, ii-I2*5 rnm. Vertex white, irrorate with brown. Antennae ciliate. Labial 

 palps with third segment 1/3 length of second, upturned, not reaching vertex. Frons projecting 

 slightly between eyes. Thorax yellowish brown. Hind tibia with proximal pair short, inner 

 spur scarcely showing through scales, distal pair of spurs with outer spur slightly more than 

 1/2 length of inner spur. Fore wing, pattern as in PI. 14, fig. 69, sandy brown with grey-brown 

 reticulations. Terminal margin incised below apex. Underside similar, paler, scattered black 

 and white scales in cell. Subapical and median fascia conspicuous on upper and under sides. 

 Veins R 3 and i? 4 stalked. Hind wing, colour and pattern as fore wing. Sc+Ri and Rs free. 



Genitalia $ (PI. 38, fig. 212). Uncus simple. Gnathus a weakly sclerotized loop. Valve 

 simple. Median basal process well sclerotized. Juxta a broad plate deeply divided in middle 

 with few small spines apically. Aedeagus with small sclerotized plate-like cornutus and spiny 

 vesica. 



?. Unknown. 



Discussion. Some variation is present in the colour of the specimens examined, 

 the Kenyan specimen being darker than the Ugandan one. There is also slight 

 variation in the shape of the juxta. The relationships of this species are not clear. 

 Basically it fits into the genus Kuja but has certain peculiarities of its own, such as 

 the fusion of R z and R 4 for part of their length in the fore wing and the more strongly 

 ciliate antennae. The pattern is fairly typical of the squamigera-group. From the 

 other species in the group, kibala can be separated by the fusion of the radial veins 

 of the fore wing and the ciliation of the antennae. The relationship between kibala 

 and majuscula is not clear, they differ in wing venation but otherwise are rather 

 similar.
