alternative definition added over 13 years ago by Istvan Miko
In some ant taxa, a sound-producing system consisting of a sharp scraper (the plectrum) located on the posterior border of the postpetiole and of a file of transverse ridges (the stridulitrum) located on the upper surface of the anteriormost part of the abdominal segment 4. When the gaster is jerked up and down, the plectrum rubs against the stridulitrum, producing the stridulation.
