Résumé
In the «Massif Central » of France (Mont Mézenc) the earwig Chelidura pyrenaica is represented by a population characterized by the shape of the male cerci, more robust and less arcuate. This population corresponds to a well defined sub-species which is named ssp. arverna. This subspecies was compared to the nominal one by a biometrical analysis which resulted in the definition of the best criteria of discrimination.
