Dorsum (left) and venter of hypopus of Tytodectes podager, from Domrow (1981).

Belongs within: Astigmatina.

The Hypoderatidae are a group of astigmatine mites found in vertebrate nests, many of which are only known from parasitic deutonymphs (OConnor 2009).

Characters (from OConnor 2009): Adult with body cuticle usually smooth or with scale-like ornamentation; palpi reflexed inward; propodosoma with lamellar (le) setae absent; discrete coxal apodemes III–IV present, projecting obliquely from bases of trochanters; tibiae I and II with two ventral setae; tarsi with both tectal setae filiform, similar in length; empodial claws absent; opisthosoma usually bilobed posteriorly; female oviporus longitudinal with genital valves fused to body anteriorly, free posteriorly. Deutonymph with all traces of attachment organ completely absent; legs well developed; coxal setae 3a and 4a absent; tibiae III–IV without comb-like setae; posterior coxal apodemes often with indistinct edges.
