The Damaeidae are a group of oribatids that are most diverse in humus and litter in temperate and boreal regions of the Holarctic. They may be distinguished from other oribatids by their moniliform legs, with femora and tibiae narrow proximally and swollen distally (Norton & Behan-Pelletier 2009). The classification of many genera within the Damaeidae is based heavily on setal counts and is quite probably artificial (Balogh & Balogh 1992).

Characters (from Norton & Behan-Pelletier 2009): Adults with scalps present or absent, sometimes with mass of debris on notogaster. Cerotegument often dense and conspicuous, covering body and setae. Prodorsal lamellae and costulae absent; tutorium absent; well-developed parastigmatic enantiophysis present. Dorsophragmata and pleurophragmata absent. Subcapitulum diarthric; palpal eupathidium acm separate from solenidion; genal notch absent. Notogaster with eleven pairs of setae, of which nine pairs in longitudinal row. Genital plates with 6 pairs of setae. Legs moniliform; seta d present or absent on tibiae and genua when respective solenidion is expressed. Tarsus II with two solenidia. Larva unideficient; nymphs eupheredermous, quadrideficient; immatures with seta d present on tibiae and genua when respective solenidion is present.
