Dorsal (left) and lateral views of Beklemishevia barbata, from Balogh & Balogh (1992).

Belongs within: Oribatida.
Contains: Palaeacaridae, Archeonothridae.

The Ctenacaroidea are a group of poorly sclerotised oribatids with tridactylous leg tarsi and usually more or less expanded bothridial setae (Norton & Behan-Pelletier 2009).
