• Haidomyrmex scimitarus,

Haidomyrmex zigrasi Barden & Grimaldi – reconstructions based on two entirely complete dealate (H. scimitarus) and worker (H. zigrasi) specimens suggested that the enigmatic L-shaped mandibles probably articulated, at least partially, in a vertical plane. In particular, the placement of trigger hairs on the clypeus as well as the hypognathous-like orientation of the head (all other non-haidomyrmecine ant heads are prognathous; Keller, 2011) suggested that hell ants were Cretaceous analogues to modern trap-jaw predators ( Barden & Grimaldi, 2012). H. scimitarus is also the largest haidomyrmecine, measuring over twice the total length of most other species.
