Parasitidae

Parasitidae is a family of predatory mites in the order Mesostigmata that has worldwide distribution. They are the only family in the superfamily Parasitoidea. Relatively large for mites, their color is often yellowish to dark brown. The family as a whole preys on a wide variety of microarthropods and nematodes, with individual species usually having a narrower range of prey. The family contains two subfamilies, 29 genera, and around 400 species.

Poecilochirus is a Holarctic genus of mites in the family Parasitidae. They are relatively large (ca. 0.5-1mm) and often found on rotting corpses, where they are transported by beetles. Deuteronymphs are characterized by two orange dorsal shields and in many species a transverse band on the sternal shield. The juvenile development consists of a larval stage (three pairs of legs), protonymph, and deuteronymph, but no tritonymph. Females are smaller than males. Males guard female deuteronymphs shortly before these mate, and pairs mate venter-to-venter.
