Schizomida (common name shorttailed whipscorpion) is an order of arachnids, generally less than 5 millimetres (0.20 in) in length. The order is not yet widely studied. As of 2005, more than 230 species of schizomids have been described worldwide, most belonging to the Hubbardiidae family. A systematic review including a full catalogue may be found in Reddell & Cokendolpher (1995).
