Given the coloration of the legs and the site of observation (Belgium), I would suggest Machimus atricapillus. About the only alternative is M. cingulatus, but that species has differently colored tibia. There are a few very rare species that occur in Germany that I skip (eg. M. poecilogaster, M. pyragra).
