Acarina
Acarina or Acari are a
taxon of
arachnids that contains
mites and
ticks. The diversity of the Acari is extraordinary and its fossil history goes back to the
Devonian era. As a result, acarologists (the people who study mites and ticks) have proposed a complex set of taxonomic ranks to classify mites. In most modern treatments, the Acari is considered a
subclass of
Arachnida and is composed of 2-3 orders or superorders:
Acariformes,
Parasitiformes, and Opilioacariformes. The latter is often considered a subgroup within the Parasitiformes. The monophyly of the Acari is open to debate and the relationships of the acarine orders to other arachnids is not at all clear.

Milben
Milben (Acari) sind eine
Ordnung der
Spinnentiere (Arachnida) im
Stamm der Gliederfüßer. Milben stellen mit ca. 50.000 Arten in 546 Familien die größte Gruppe der Spinnentiere. Da sie die kleinsten
Gliederfüßer (Arthropoda) sind, ist davon auszugehen, dass viele Arten noch gar nicht entdeckt wurden.
