 History). 



Elephantomyia nitidithorax is closest to E. wahlbergi, 

 Bergroth (Caffraria), from which it is distinguished by the 

 different coloration of the praescutum and pleura, the dark 

 brown legs, the differently coloured abdominal tergites, and 

 the venation, the latter assuming that Bergroth's comparison 

 of his species with the genotype, E. westwoodi, is correct.
