The author presents new data about the collembolan species collected from the Piatra Craiului Massif. Sixty-five species were identified from the material sampled from soil and mesovoid shallow substratum (M.S.S.) Three species (Arrhopalites ornatus Stach, 1945, Microgastrura duodecimoculata Stach, 1922 and Xenylla mucronata Axelson, 1903) are for the first time recorded in the Romanian fauna.
