Phytoseiid mites (Acari: Phytoseiidae) from Argentina, with description of a new species Author Guanilo, Alberto Daniel Author Moraes, Gilberto José De Author Toledo, Silvana Author Knapp, Markus text Zootaxa 2008 1884 1 35 journal article 10.5281/zenodo.184278 46abdf39-818b-4fe3-8791-d3b7de923356 1175-5326 184278 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. 1.
