Chelicerata

Los acaros pertenecen al Phylum Arthropoda, Subphylum Chelicerata, clase Arachnida, subclase Acari.

Entre los 129 capitulos que versan sobre la sistematica de Arthropoda, tres se refieren a taxones afines al grupo de artropodos: "Pentastomida", "Onychophora" y "Tardigrada"; en tanto que 126 resenan los taxones caracteristicos de Arthropoda, asi los grupos de Chelicerata se incluyen en 14 capitulos relativos a "Xiphosura", "Pycnogonida", "Palpigradi", "Schizomida", "Uropygi", "Amblypygi", "Solifugae", "Ricinulei", "Araneae" "Scorpiones", "Pseudoscorpionida", "Opiliones", "Acari" y "Oribatei (Acari)"; y en cuatro capitulos de Myriapoda se discuten "Symphyla", "Pauropoda", "Geophilomorpha" y "Diplopoda".

Refuse, soil, and chelicerata (ticks (Ixodidae)) and horseshoe crab (Limulus polyphemus) were found in 4%, 6.

In other regions, although rare, Chelicerata were also found in the Permian (Stormer et al.

Ticks are members of the Kingdom Animalia, phylum Arthropoda, subphylum Chelicerata, class Arachnida, and order Acarina.

From variable to constant cell numbers: Cellular characteristics of the arthropod nervous system argue against a sister-group relationship of Chelicerata and "Myriapoda" but favour the Mandibulata concept.
