Asphinctanilloides

Small hypogaeic blind ant predators with subterranean legionary habits. Their hypogaeic habits may, in concert with collecting techniques that have vastly undersampled ants with such a lifestyle, explain the paucity of information about these ants. Museum collections hold few specimens of these ants.

Identification
Similar to Leptanilloides.

Alitrunk flat without metanotal groove on dorsum; abdominal segments 5 and 6 (gaster segments 2 and 3) with a distinct, much narrower presclerite and wider postsclerite, resulting in constrictions between abdominal segments 4 and 5 (gaster segments I and 2), and 5 and 6 (gaster segments 2 and 3). . . . . Leptanilloides

Alitrunk flat with a metanotal groove on the dorsum; abdominal segments 5 and 6 without separation into pre and postsclerites and thus without constrictions between abdominal segments 4 and 5, and 5 and 6. . . . . Asphinctanilloides

Biology
Anecdotal observations suggest these ants ("Leptanilloidinae" species) behave as army-ant like predators. These ants are likely to be largely subterranean, occasionally coming to the ground surface under debri (rocks, downed wood, etc.) while foraging or to allow mature sexuals (either males only or perhaps males and females) to leave their natal nest. Group predation, frequent colony migrations and synchronized brood cycles may also be part of their life history.
