Within the subfamily of Dasycerinae the only genus Dasycerus is represented by 17 mycophagous beetles. Besides four species from USA, the remaining species cover a wide range in the Palaearctic and Oriental region, with, as far as we know only Dasycerus sulcatus (1.9-2.3 mm) ( Fig. 27 ) occurring in Belgium with expansion across Central Europe, France, and Italy (LÖBL & CALAME, 1996). The first notification were observations nearby the frontier with France ( COULON, 1987), supplemented with one recent mention from Buzenol in 2020 ( Luxembourg – www.waarnemingen.be) and ever since no other publications have added new data. D. sulcatus is a litter-dwelling species, found on fruiting bodies of fungi. Only two specimens have been collected (Annex); Voeren (GS0227) in 2007 and one specimen observed by sifting the decayed wood of an old oak tree in Tongeren (2009) colonised by the ant L. brunneus .
