New genera, species and songs from southern Spain!

S. Puissant & J. Sueur published recently an important paper with descriptions of 3 new species, one subspecies of Cicadettini from southern Spain. In the same paper they introduced 4 new genera replacing the formerly used genus Tettigetta: Tettigettalna, Tettigettula, Tettigettacula and Pseudotettigetta - with the keys based on morphology and acoustics.
The new endemic taxa are: T. armandi, Tettigettalna boulardi, T. defauti and a new ssp.: T. helianthemi galantei. There are also descriptions of songs of the following cicadas: Tettigettacula baenai, Tettigettalna aneabi and Tettigetalna helianthemi.

Tettigetta carayoni - new song description

A description of the acoustic signals of Tettigetta carayoni from Crete (Kriti) has been published (Trilar T. & M. Gogala 2010).

Purpose and Content of this site

During last decades it became evident, that the song patterns of singing cicadas are very species specific and enable us to detect a presence of most species in a habitat without seeing and collecting them, just by recording and analyzing their acoustic emissions. In addition to this, one can recognize the hidden, morphologically inconspicuous species by analyzing and comparing their songs. As it is well known, in singing cicadas only males have characteristic sound producing organs - tymbals and are able to produce loud and species specific sound signals. Nevertheless, females of some species can answer to the courtship signals of males by short wing clicks. Similarly, males of some species use wing clicking as additional sound producing mechanism.

Oscilograms, spectrograms and spectra

On our pages we offer samples of songs for comparison in MP4 format. For graphical comparison of song patterns we are providing also oscillograms (c), spectrograms - (b)(also called sonograms or sonagrams) what means a 3-dimensional presentation of sound intensity in a frequency versus time plain. For this purpose we originally used Canary 1.2.4 (Cornell University) and recently Amadeus Pro software (© Hairersoft) for Mac computers. SnapzProX software (© Ambrosia Software) has been used to produce QuickTime or RealPlayer mov files and for conversion to MP4 the MPEG Streamclip 1.9 ©.
