Diagnosis.
Species of the genus can be recognised by a combination of the following characters. The pronotum carries a spine behind the ventro-anterior angle of the pronotum, the male pronotum is prolonged behind and bulbous; the paranota of pronotum have the auditory swelling modified (usually with a fold); the mesosternal lobes are long-conical and with an additional spine at each anterior angle (sometimes weak); there is a spine at the anterior margin of the mesosternal plate; pro- and mesofemur are provided on ventral margins with larger spines that are alternating with minute spinules; the wings are strongly abbreviated, in male micropterous and largely hidden under the prolonged pronotum, in female squamipterous; the male phallus is lacking titillators, instead the cerci are greatly modified; the female ovipositor is dagger-shaped.
