Distribution. Russia: *Primorskiy Terr., *Jewish AP, *Amurskaya Prov., *Khabarovsk Terr., *Sakhalin, *Kuril Islands (Kunashir, Iturup), Kamchatskiy Terr. (Blüthgen 1935), *Magadan Prov., *Chukotskiy AA, Western Siberia, European part (Osytshnjuk et al. 1978); Japan: Hokkaido, Honshu, Shikoku, Kyushu (Mitai & Tadauchi 2013, as Sphecodes silvicola), North Africa, Europe (north to 66 °), Turkey, Near East.
Remarks. We studied numerous materials of S. geofrellus from Europe, Central Asia, Urals and Siberia. Male and female specimens examined from Japan identified as S. silvicola by K. Mitai proved to be S. geofrellus. Description, figures (Tsuneki 1983) and redescription (Mitai & Tadauchi 2013) of S. silvicola also unequivocally indicate identity with S. geofrellus. For this reason we propose S. silvicola as a new junior synonym of S. geofrellus.
