Superfamily FORMICOIDEA 1333 



Subfamily CERAPACHYINAE 



This small subfamily, found in the tropical regions of the world, exhibits a blending of doryline 

 and ponerine traits both morphologically and biologically. Only three species are known from 

 north of Mexico. Little is known concerning the behavior of the New World forms, but they are 

 predaceous and carnivorous and the colonies are small. Wilson (1958) studied the behavior of 

 several species from Melanesia and Australia and found them all to be myrmecophagous, feeding 

 on the broods and sometimes adults of other species of ants. He suggested that these ants carry 

 on an alternating, group foraging and raiding behavior pattern by which the colony efficiently 

 exploits the surrounding territory. 



After this section was completed, Brown (1975) published on the Cerapachyinae and regarded 

 the Cerapachyini and Acanthostichini as tribes of the Ponerinae, consequently not recognizing 

 the Cerapachyinae as a subfamily.
