THYRIDIDAE OF AFRICA AND ITS ISLANDS 37 



Discussion. This species is very variable in size and pattern but little variation 

 has been found in the structures of the genitalia. There is a tendency for the South 

 African specimens to be smaller than the specimens from West Africa but there is 

 overlap in size. The largest specimen is a female from Mt Elgon, Uganda. Although 

 over 50 specimens were examined, no distinct trend to subspeciation was detected 

 in this widespread species.
