description: 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.
