(entomology) A distinctive characteristic of a group of ants in which another segment is present in the pedicle, i.e. between the petiole and the gaster.


(Entomology) The petioles in ants can be used for their identification. Some ants would have only one segment (petiole) while others have two segments (the petiole and the post-petiole).

Word origin: post- meaning after + Latin petiolus meaning little foot (from pēs foot).
