Aneuretus simoni is the only species of Aneuretus and is the only extant member of the subfamily Aneuretinae. Long believed to be a basal lineages of Formicidae, molecular phylogenetics have shown the group is closely related to the Dolichoderinae (see the subfamily phylogeny).

At a Glance • Monotypic  


Sting (that may not be visible), single petiole with a long, narrow anterior peduncle, propodeum armed with a pair of spines. Major tibial spur of hind leg simple or with a few minute barbules. Palp forumula 3,4. Only known from Sri Lanka.

In the field workers resemble small yellow Pheidole minors in their morphology. Behaviorally they have a tendency to keep their long petiole folded up against their propodeum with their gaster slightly elevated.
