Halictophagus silwoodensis new for the Netherlands (Strepsiptera: Halictophagidae) The first record of Halictophagus silwoodensis Waloff, 1981 for the Netherlands is presented. Seven of the 64 specimens of Ulopa reticulata (Fabricius, 1794), the host of H. silwoodensis taken at a small patch of Calluna at Elst (province of Utrecht) had empty male puparia between the tergites (fig. 5). At several other locations specimens of U. reticulata were examined, but yielded no further specimens of H. silwoodensis. The biology of both the host and it’s parasite are briefly discussed. Furthermore it is discussed that probably several other species of Strepsitera are likely to occur in the Netherlands but have yet to be found.
