The collecting was carried out by two Townes type Malaise traps during one year from May 2015 to May 2016. Altogether 2,270 specimens were collected belonging to 148 species. Fifty-two species and five genera were recorded from Belgium for the first time. The general distribution and systematics of these new species have been briefly discussed. A list of the species including complete account of collected material, is provided. Fungus gnats were observed to be active all year around with more species diverse periods in May-June and October. A considerably large and remarkably coloured species, Greenomyia mongolica, is discussed to have a possibly invasive character of distribution in Europe. A set of photographs illustrating representatives of all recorded 46 fungus gnats genera has been included.</p>
