An annotated list, key to twenty four species of spider mites (Prostigmata: Tetranychidae) known from Israel is provided. About half of the species are considered to be exotics, having invaded Israel ithin the last fifty years. Nine species, all of which belong to the subfamily Tetranychinae: Eutetranychus orientalis, Eutetranychus palmatus, Oligonychus afrasiaticus, Oligonychus perseae, Panonychus ulmi, anonychus citri, Schizotetranychus asparagi, Tetranychus turkestani and Tetranychus urticae, are agricultural pests, whereas the others have little economic impact, or else are controlled by their natural enemies.
