Résumé
Collection efforts in the framework of the European All Taxa Biodiversity Inventory conducted in the Mercantour national Park located in the Alps mountain range of southern France disclosed three new species of Tetranychid mites. The species described in the current paper are: Bryobia cinereae n. sp., Bryobia mercantourensis n. sp. and Eotetranychus quercicola n. sp.. Both Bryobia species were collected on Genista cinerea and E. quercicola on Quercus pubescens. A new combination is also proposed for Bryobia longisetis, previously placed in Pseudobryobia byWainstein (1960).
