AGROECOMYRMECINAE is a subfamily of ants containing two extant and
two fossil genera. The subfamily was originally classified in 1930 by
Carpenter as AGROECOMYRMECINI, a

* large mandibles with mandibular masticatory margins that oppose at full closure but do not overlap * eyes at extreme posterior apex of deep antennal scrobes * clypeus very broadly triangular, broadly inserted between the frontal lobes * antennal sockets and frontal lobes strongly migrated laterally, far apart and close to lateral margins of the head * mesotibia and metatibia with pectinate spurs * short and compact mesosoma * a sessile petiole , in posterior view the tergite and sternite not equally convex * an abdominal segment III (postpetiole) without tergosternal fusion, segment large and very broadly articulated to segment IV, * a helcium in frontal view with the sternite bulging ventrally and overlapped by the tergite * an abdominal segment IV with a complete tergosternal fusion, * abdominal segment IV with a stridulitrum on the pretergite * the sternite of abdominal segment IV is reduced, the tergite is much larger than the sternite and strongly vaulted
The subfamily rank of the armadillo ants was reassessed by Baroni
Urbani & de Andrade (2007) in their last systematic assessment of the
dacetines . They analyzed a morphological dataset that included former
dacetines, basicerotines , phalacromyrmecines , and Tatuidris, as well
as other non-
* mandibles at rest opposing at least in part, instead of crossing * a mandibular-torular index < 130 * reduction of maxillary palps from double-jointed to single-jointed * reduced male mandibles * presence of a two-segmented antennal club * reduced number of antennal joints
In addition, two autapomorphies (a differently shaped petiolar tergum and sternum , and the eyes at or close to the apex of the antennal scrobe) separated Tatuidris from all other extant ant genera included in their study.
Unlike phylogenetic studies based on morphological traits, molecular
analyses of the internal phylogeny of the ants have given strong
evidence that the armadillo ants are neither closely related to nor
nested within the Myrmicinae. Brady et al. (2006), Moreau et al.
(2006) and Rabeling et al. (2008) reconstructed phylogenetic trees
with the agroecomyrmecines inside the 'poneroid' group of subfamilies,
close to the
Paraponerinae , and gave support for the exclusion of the
genus from the Myrmicinae, a subfamily located inside the 'formicoid'
clade. Given the early appearance of the
Recently, Keller (2011) challenged the phylogenetic relationships of the poneromorph subfamilies (including Tatuidris).
