Key to the Phytoseiidae  reported from Argentina

A key is subsequently provided for the species reported to date from Argentina. A. hexagonus  , A. perlongisetus  and E. finlandicus  are not included because of the uncertainties about the identity of the first 2 species and because of the strong evidence that the report of the last species could correspond to a misidentification, as discussed previously in this paper.
