Fig. 108. Total known localities and range of the milliped genus Brachoria. 

 Within this small area occur twenty-five species, many of them sympatric, 

 which evidently evolved within this small area. Above is shown the range of 

 Brachoria and below is shown the phylogenetic history of this geographically 

 restricted evolutionary development. (Modified from Keeton.)
