A diagnosis of European Phrudinae is given and a key is presented for Seleucus cuneiformis Holmgren and eleven European species of Phrudinae. Seleucini Vikberg trib. nov. in Ctenopelmatinae is proposed for Seleucus Holmgren. Astrenis nigrifacies Vikberg sp. nov. (Finland, Sweden, England, Scotland, France), A. brunneofacies Vikberg sp. nov. (Finland, Sweden, England, Scotland, Germany, Italy), Phrudus compressus Vikberg sp. nov. (Finland, Sweden) and the males of A. paradoxus (Schmiedeknecht) and P. badensis Hilpert are described for the first time. All other species are redescribed, and new distributional data are reported. The dentation of the claws and the form and location of modified sensory structures on the subbasal flagellomeres are used as taxonomic characters. Pygmaeolus nitidus (Bridgman), Astrenis nigrifacies, A. brunneofacies, Phrudus defectus Stelfox, P. compressus and P. badensis were found to be associated with ageing logs of Pinus sylvestris L. and Picea abies (L.)
