  Quotations
  The stridulatory mechanisms and sound patterns in these groups probably reflect the origins of acoustic communication in Orthoptera, particularly since many of the primitive genera lack ears and appear to use sound only for defence, as a plesiomorphic (primitive) condition (Field, 1993a).
