notes

during the last 50 years the number of described gall-mites has considerably increased, and this applies in particular for grass-inhabitants. Many are not symptomatic, therefore not treated in this website. Even more than for other groups of plants one should realise that for grasses the combination plant species + symptom is insufficient for a reliable identification.

Moreover, DNA-analysis has demonstrated that “A. hystrix” actually is a complex of a number of species (Skoracka & Dabert, 2010a).
