Show abstract
Ninety hybotid species are recognized in the Botanic Garden Jean Massart (Brussels), representing 52 % of the hybotids ever recorded in Belgium. Two species new to science are described: Platypalpus massarti sp. nov. and P. pictitarsoides sp. nov. Following species are reported for the first time in Belgium: Drapetis infitialis (Collin, 1961), Platypalpus negrobovi Grootaert, Kustov & Shamshev, 2012 and Trichina opaca Loew, 1864. In addition, comments are given on a selected number of species: Bicellaria intermedia Lundbeck, 1910, Platypalpus aurantiacus (Collin, 1926), Platypalpus longimanus (Corti, 1907), Platypalpus nanus (Oldenberg, 1924), Platypalpus rapidoides Chvala, 1975, Platypalpus subtilis (Collin, 1926), Stilpon subnubilus Chvala, 1988 and on the genus Hybos Meigen, 1803. The holotype of P. cryptospina (Frey, 1909) is revised. Only 30 species or 33% of the species present are in a Safe/Low risk Red Data Book category meaning that the other 66% are in a more or less Threatened category.
