The Hexacentrinae, are a subfamily of predatory bush crickets or katydids. The type genus is Hexacentrus, which may be known as "balloon-winged" bush crickets/katydids etc., is also the most speciose and widespread in Africa and Asia.
Description
The group has sometimes been treated as a tribe (as "Hexacentrini") within Conocephalinae, which may be a sister group.
A.V. Gorochov described the following characters for this subfamily:
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.
