Remarks. In addition to Russian Far East material of S. longulus , we studied specimens from Western Europe, Central Asia and Siberia. Variablity of this species is limited and mainly evident in density of body punctures and the size of velvet-like areas on male flagellomeres. Male and female specimens from Japan identified as S. amakusensis by K. Mitai proved to be S. longulus , and description ( Yasumatsu & Hirashima 1951) and redescription ( Mitai & Tadauchi 2013) of S. amakusensis also indicate identity with S. longulus . We therefore propose S. amakusensis as a new junior synonym of S. longulus .
