A new species of the subfamily Ctenopelmatinae, Syndipnus depressus sp. nov. with strong dorsoventral compression of the metasoma, is described from Poland. Similarity of the new species to two ctenopelmatine species of the tribe Mesoleiini (Mesoleius phyllotomae Cushman, 1933 and M. aceris Shaw et Kasparyan, 2003), endoparasitoids of leaf mining sawflies of the genus Heterarthrus Stephens, 1835 (Tenthredinidae: Heterarthrinae), suggests that the new species may have similar hosts.
