Deutonymph of Myianoetus, copyright Olivier9099.

Belongs within: Astigmatina.
Contains: Histiostoma.

The Histiostomatidae are a group of astigmatan mites found on wet substrates, most commonly feeding by filtering organic particles and microorganisms from the water film. Most species are associated with isolated or ephemeral habitats and some may have the shortest development times of any astigmatan mites, going through their entire life cycle in as little as six days. Deutonymphs are typically adapted for phoretic transport by insects though species show marked diversity in development of the attachment organs (OConnor 2009).

Characters (from OConnor 2009): Adult with body not dorsoventrally flattened; chelicerae laterally compressed, often attenuate, usually with numerous finely divided teeth, nonchelate; palpi with terminal solenidion and usually at least one elongate eupathidial seta, normal setae strongly reduced, usually reflexed outward; genital papillae ring-like, usually not directly associated with the genital opening; female genital valves fused to body posteriorly, open anteriorly forming a transverse oviporus. Deutonymph with Legs III–IV with femur-genu-tibia-tarsus partially or completely fused; legs III–IV flexed at trochanter-femur articulation and directed anteriorly in repose; rostral and lamellar pairs of setae absent; setae 4b absent.
