摘要: Summary. 1 An account is given of the anatomy organs sound production and reception in Tettigarcta tomentosa T. crinita, primitive cicadas from Australia. 1 This genus provides a link between Cercopids true makes it possible to suggest detailed homologies for muscles other structures concerned sound-production. It concluded, contrary Pringle (1954), that tymbals tymbal are developments first abdominal segment. 1 The evolution inter-sexual signalling Homoptera Auchenorrhyncha discussed general terms. suggested system may have originated movements made during copulation evolved through stage involving pulse vibrations.
