Notes: [Original title: Variabilité morphologique chez Pseudaulacaspis pentagona Targioni-Tozzetti dans une population du sud-est de la France (Hemiptera: Diaspididae). Conference proceedings: Actes de la IVème Conférence Internationale Francophone d'Entomologie, Saint-Malo (France, 5-9 juillet 1998).] The population of the white peach scale Pseudaulacaspis pentagona (Targioni-Tozzetti) (Hemiptera, Diaspididae) has a morphological variability in the same population that has been reared since more than a hundred generations on potato tubers. Among them, some specimens have the same characteristics as a related species, Pseudaulacaspis prunicola (Maskell). We conclude that it must be the same species.
