Een overzicht van de nieuwe vindplaatsen van de Rivierrombout (Gomphus flavipes) in Nederland in 1999

Termaat, T., 2000. Survey of new riverine habitat of Gomphus flavipes in The Netherlands in 1999. Brachytron 4(1): 13-17. After the rediscovery of Gomphus flavipes in The Netherlands in 1996, the species was recorded in 1998 in eight 1x1 km-squares along the river Waal near Nijmegen in the eastern part of The Netherlands. Extensive research in 1999 displayed the species presence at many new locations of Gomphus flavipes along the rivers Waal, Nederrijn, Nieuwe Merwede and Beneden Merwede. One wandering male was found near Goirle outside the species normal riverine habitat, at short distance of the Belgian border. An overview is presented of all new locations, many reaching well westwards. In addition, all locations where the species appeared to be absent despite searching are presented also. Possible reasons for absence of Gomphus flavipes along the river Lek are discussed, just as the possibilities for the species presence along other river systems.
