Subfamily APHILANTHOPSINAE 

 Tribe APHILANTHOPSINI 



This tribe occurs only in the Nearctic Region. Its members prey only upon ants, the more 

 primitive Aphilanthops on winged queen ants. The other two genera prey upon harvester ant 

 workers and have developed a complex mechanism at the apex of the abdomen which is used in 

 prey transport.
