General information
Postpetiolus is a special segment of the metasome of insects having a two-membered stalk located between the petiol and the abdomen [1] .
Ants have two-segmented ( petiolus + postpetiolus) and single-segmented ( petiolus + flake). The number of segments and the shape of the stem are very important for determining the species. For example, in ants of the subfamily Formicinae, the stem is single-segmented, and in Myrmicinae, it is two-segmented [2] .
