Ordines (16 + 4†): Amblypygi – Araneae – †Haptopoda – Holothyrida – Ixodida – Mesostigmata – Opilioacarida – Opiliones – Palpigradi – †Phalangiotarbida – Pseudoscorpiones – Ricinulei – Sarcoptiformes – Schizomida – Scorpiones – Solifugae – Thelyphonida – †Trigonotarbida – Trombidiformes – †Uraraneida

incertae sedis: †Saccogulus

The 6 ordines Holothyrida, Ixodida, Mesostigmata, Opilioacarida, Sarcoptiformes and Trombidiformes are sometimes grouped together as Acari, but there is no consensus on classification above ordinal level, making a Linnean classification difficult.
