 The structure of the abdominal region can separate it from other Myrmeciinae relatives (the fourth abdominal segment of "Myrmecia" is tubulate, whereas "Nothomyrmecia" has a non-tubulated abdominal segment).The appearance of the fourth abdominal segment is consistent with almost all aculeate insects, and possibly "Sphecomyrma".The feature of non-functional, vestigial wings may have evolved in this species relatively recently, as wings might otherwise have long-since disappeared completely had they no function for dispersal.
