THYRIDIDAE OF AFRICA AND ITS ISLANDS 121 



The SQUAMIGERA -Group 



This group includes eight species. The first four species are very similar in pattern 

 but distinct in genitalia. K. squamigera has a slightly "winged" uncus reminiscent 

 of the species in the gemmata-gr owp. External morphology and pattern are similar 

 in the squamigera-group but the genitalia are very distinct. K. kibala and K. 

 majuscula have a slightly different fore wing venation from the other species in the 

 group. 



The squamigera-gronp is separated from the gemmata-gr o\xp mainly by the very 

 distinctive wing pattern and the rounded (not angular) termen.

o*. Wing, 15-18 mm. Vertex brown, frons rounded, irrorate with white. Labial palps 

 with third segment 1/4 length of second, upturned, not reaching vertex. Thorax brown. 

 Hind tibia with proximal pair of spurs slender, inner spur long, slightly clavate, 4 X length of 

 outer spur. Distal pair of spurs with outer spur slightly more than 1/2 length of inner; inner 

 spur 2/3 length of 1st hind tarsal segment. Fore wing, pattern as in PI. 13, fig. 63, yellow-brown 

 with darker grey-brown markings. lA and iA anastomose near base to form single vein to 

 wing margin. Underside, darker than upper with prominent patch of iridescent black and 

 white scales near apex of cell (PI. 13, fig. 64). Hind wing, Sc +i?j and Rs free. Colour as fore 

 wing, small patches of black scales in basal area. Median fascia with orange-yellow and black 

 scales. Underside darker than upper, lacking iridescent scales of fore wing. 



Genitalia^ (PI. 37, fig. 207). Uncus thickened with prominent dorsal projection. Gnathus 

 a lightly sclerotized loop slightly thickened in middle. Valves with enlarged sacculus and 

 sclerotized median part. Juxta 3-lobed, "W"-shaped, strongly spined. Aedeagus thin, broader 

 near base, no cornuti. 



$. Wing, 18 mm. Colour and pattern as male, including scale patch under fore wing. 

 Labial palps with third segment nearly 1/2 length of second. Hind tibia with outer spur of 

 proximal pair 1/4 length of inner spur. Inner long spur not clavate as in male. 



Genitalia $ (PI. 60, figs 367, 368). Anal papillae short. Ostium and first part of duct 

 sclerotized, bursa without signum. Opening of duct on Vlllth segment (contrast obliquifascia 

 where opening is intersegmental between VII and VIII). 



Discussion. Externally this species is similar to both obliquifascia and fracti- 

 fascia, but the amount of curvature of the subapical line can be used to separate 

 these species. In squamigera the arc made by this line is sharp and deep, in 

 obliquifascia it tends to be rather shallow and in fractifascia this arc is incomplete. 

 In the genitalia considerable differences occur between these species which suggests 

 that the group is not a natural one but the other morphological features are similar. 

 The diverse forms of the genitalia in these species may indicate that the fore wing
