Acarus siro
Trogulus nepaeformis

Etymology[edit]

From Ancient Greek ἀράχνη (arákhnē).

Proper noun[edit]

Arachnida

  1. A taxonomic class within the subphylum Chelicerata — the spiders, scorpions, harvestmen, mites and ticks, having four pairs of thoracic appendages.

Usage notes[edit]

Consensus is lacking for taxonomic classification between the class and order levels. The subclass Acari is sometimes used, but doing so leads to an incompletely specified level.
