Description

The group has sometimes been treated as a tribe (as "Hexacentrini") within Conocephalinae, which may be a sister group.[2][1]

A.V. Gorochov described the following characters for this subfamily:[1]

  • rostrum of head narrow with simple, moderately long mandibles, without distinct sexual dimorphism;
  • flat, wide hind lobe of the pronotum with thoracic sternites having a pair of spines or finger-like processes;
  • fore and middle legs have tibiae with long spines, especially on the ventral surface (for predation);
  • hind wings (if not shortened) with developed “costal lobe”, and a characteristic thickened crossvein;
  • anal plate and epiproct rather simple (no distinct specializations) in both sexes, but male paraprocts have a finger-like process or distinct lobule at their apex.
