Aneuretus

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).

Identification
Live workers morphologically resemble somewhat odd, small yellow Pheidole minors. Behaviorally they keep their long petiole folded against their propodeum and hold 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.
