Belongs within: Parasitengonina.

The Chyzeriidae are a group of parasitengonine mites in which adults usually bear numerous setiferous, finger-like projections on the idionotum (Walter et al. 2009).

Larva heteromorphic; palpgenu with one seta; idionotum with prodorsal plate (scutum) bearing four pairs of setae including one pair of trichobothria but lacking scutellum, setae c1 located on paired platelets; ventrally with sessile urstigmata and well-defined anus, anal plate bearing two pairs of setae; coxal plates I–III bearing 2, 1, and 1 setae, respectively, plates I–II contiguous; legs with genua each bearing four setae.
