 useful summary of the antecedent literature. 



IDENTIFICATION 



Males are easily identified in the African fauna. They have 

 no caudal appendage on the posterior body margin and the inner 

 margin of the adanal shields does not project posteriorly as a 

 spine. Palpal segment I is withovrt a ventral bristla- bearing 

 protuberance. The hypostome formula is Lr/ k and the denticles 

 are noticeably finer than those of B. decoloratus . In size, 

 males are about the same as those oT B. decoloratus . 



Females are usually readily separated from B. decoloratus by 

 absence of a deep gap between the inner and outer spurs of coxa I. 

 A shallow concave eraargination replaces this gap. There is no 

 bristle- bearing protuberance on the internal ventral margin of 

 palpal segment I; this margin is fairly elongate and mildly con- 

 cave. The scutal margins anterior of the eyes are visually 

 straight and parallel. The scutum is definitely longer than wide. 

 The hypostome formula is as for the male. The color of this spe- 

 cies is usually paler than that of B. decoloratus .
