Diagnostic characters

  • Divided dorsal shielddivided dorsal shield:
    in Mesostigmata, adult mites have two usually subequal dorsal shields.
  • Shield-shape intercoxal shield
  • Acrotarsus often present on legs I
  • Phoretic on insects and other animals

Similar taxa

Deutonymphs of Pergamasinae lack the acrotarsusacrotarsus:
(=apicotarsus) distal subdivision of the tarsus, usually of tarsus I (NB—not to be confused with the ambulacral stalk or pretarsus)
 on legs I and are not phoretic on insects or other animals.

Taxa keyed separately: Gamasodes Oudemans, Poecilochirus G. & R. Canestrini

Comments

In general, immature mites can only be identified if they can be associated with adult females. However, some of the bingo characters may work on immatures, as in the case of a monogynaspidmonogynaspine:
(monogynaspid) representative of the mesostigmatan suborder Monogynaspida, characterized by having a single genital shield in the adult female that usually bears one pair of setae (st5) or may be nude.
 mite with an acrotarsusacrotarsus:
(=apicotarsus) distal subdivision of the tarsus, usually of tarsus I (NB—not to be confused with the ambulacral stalk or pretarsus)
