THYRIDIDAE OF AFRICA AND ITS ISLANDS 57 



pattern and genitalia are sufficiently distinct from fuliginea (which occurs in the same 

 locality) for inoptata to be regarded as a distinct species. Some variation in colour 

 occurs, mainly in the extent of the black terminal margins. In some specimens this 

 extends nearly to the cell from the terminal margin of the fore wing. In a few 

 specimens there is also a small translucent area in the fore wing.

Holotype <j>. Ghana: N. Territories, Kete-Krachi (Cardinall), BM slide no. 

 10544, in BMNH. 

 Paratypes. Ghana: 6 $, data as holotype. 



Neobanisia zamia sp. n. 



(PI. 6, figs 19, 20; PI. 28, fig. 150) 



<J. Wing, 9 - 5-iO'5 mm. Vertex grey-bro\vn. Labial palps i£ < diameter of eye, third 

 segment 1/3 length of second. Tuft of scales on frons forming conical projection between eyes. 

 Thorax grey-brown. Hind tibia with outer spur of distal pair 2/3 length of inner spur. Fore 

 wing, pattern as in PI. 6, fig. 19, brown with yellowish brown subterminal area and some yellow 

 maculations in anterior part of median area, rest of maculations translucent. Basal area brown. 

 Underside, as upperside, paler, black spots terminally between veins. Veins i? 4 and R s with 

 short common stalk. Hind wings, colour and pattern as fore wing, Sc+R l and Rs run close to- 

 gether but do not join. 



Genitalia <J (PI. 28, fig. 150). Uncus simple, slightly clavate at tip. Socii enlarged. 

 Gnathus arms lightly sclerotized. Valve simple, narrowing in apical half. Basal process 

 toothed and heavily sclerotized, with median basal sclerotized part. Juxta a simple plate. Base 

 of sacculus strongly toothed. Aedeagus curved, vesica with small teeth. 



$. Wing, 10 mm. Pattern as male. More reddish brown colour than male. Abdomen 

 missing. Frenulum triple. 



Discussion: This species varies from reddish brown to yellow-brown, with one 

 specimen from the Mariep Mts, South Africa (PI. 6, fig. 20) lacking most of the yellow- 

 colour although having a strong reticulate pattern. The genitalia of all the speci- 

 mens are, however, similar. This species can be separated from N. joccatia by its 

 smaller size and by the narrowing of the valve of the male half way up to the apex. 

 From N. fuliginea it can be separated by colour and the shape of the basal process 

 in the male. In size, A7. zamia is similar to N. inoptata but the pattern is quite 

 different. In view of the variation, and the small number of specimens examined, 

 only the specimens from near the type-locality are considered as paratypes.
