Cecidothyris longicorpa sp. n. 



(PI. 22, figs 119, 120; PL 47, fig. 270; PI. by, figs 436, 437) 



<J. Wing, 13-15 mm. Vertex brown irrorate with white, frons brown. Antennae shortly 

 ciliate. Labial palps short. Proboscis present. Thorax brown. Fore wing, pattern as in 

 PI. 22, figs 119, 120, brown with darker brown reticulations. Costal margin darker brown and 

 dark spot in cell. Wings rather elongate, termen sharply angled. Veins i? 4 and R s anastomose, 

 R 3 and R 2 running close together, but not anastomosing. Hind wing, colour and pattern as 

 fore wing. Apex of wing pointed, anterior margin convex. Sc+R 1 and Rs approach closely 

 but do not join. 



Genitalia ^ (PI. 47, fig. 270). Uncus slender, thickened near apex. Gnathus reduced to 

 two small lateral arms, not joining in mid-line. Basal process strongly sclerotized and pointed. 

 Aedeagus with minute spines in vesica. 



$. Wing, 16—17 mm. Similar in colour to male but pattern slightly more obscure. 



Genitalia $ (PI. 67, figs 436, 437). Anal papillae short, duct with narrowing, sclerotized 

 part. 



Discussion. This species differs from all the others in the genus in the lack of the 

 prominent pectinations on the antennae. The wing shape is also very different from 

 the other species in the genus. In the other characters this species is quite typical 

 of the genus. At present this species is known only from Central Africa and its 

 relationship to the other species is not clear.
