ABSTRACT. Three new species of Pyrgodesmidae are being described from a small nature reserve supporting a seasonal tropical forest in southern Vietnam: Pseudocatapyrgodesmus pulcher sp.n., Skotodesmus vietnamicus sp.n., both representing only the second species in their respective genera, and Cryptocorypha hoffmani sp.n., an 11th species in this basically Oriental genus. These new species differ from their respective congeners chiefly in certain minor details of gonopod structure, to a lesser degree through a few peripheral characters as well.
