Aneuretus

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

Identification
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.

Biology
See the Aneuretus simoni page for information about the biology of this genus.

Castes
The single extant species of the genus has dimorphic workers.
