Subfamily Agroecomyrmecinae Carpenter, 1930

Figs 5F, 13 A–B

Diagnosis

Uniquely identified globally by petiolation of abdominal segment III (post petiole) and supraaxial helcium. Furthermore, the petiolar comformation seems to be globally unique, with the posterior petiolar foramen raised completely dorsad the anterior foramen. Identification may be confirmed with the following combination of characters: mandibles reduced, edentate; antennal toruli situated distant

from anterior clypeal margin; antenna 12-merous; meso- and metatibia with one ventroapical spur each; forewing with five closed cells; jugal lobe absent; petiolar tergum and sternum distinct; abdominal segment IV pre- and postsclerites separated by cinctus; abdominal tergum IV vaulted; abdominal tergum VIII not spiniform; abdominal sternum IX apex rounded.

Comments

Two extant genera are known in the Agroecomyrmecinae , the Neotropical Tatuidris and Afrotropical Ankylomyrma ( Ward et al. 2015) . The male of Ankylomyrma is unknown and will be a notable discovery.
