much of humid central Africa, from Sierra Leone to Uganda, but also occurs in 

 the thick woodland of the Vumba Mountains of Southern Rhodesia. The species 

 cymba is also widespread, occurring in forested regions of Nigeria and Uganda and 

 probably in much of the intervening territory. One species, bispina, is endemic to 

 Madagascar. Apart from subtilis and opacifinis, the species of Gonoreta are at 

 present poorly represented in national collections.
