Distribution. Russia: Primorskiy Terr. (Quest 2009), *Jewish AP, *Amurskaya Prov., *Khabarovsk Terr., *Sakhalin, Kamchatskiy Terr. (Alfken 1929), European part (Osytshnjuk et al. 1978); Japan (Hokkaido, Honshu), Europe (north to 64 °), Turkey, Iran, North Africa.
Remarks. We studied numerous specimens of S. crassus from Europe, Central Asia, the Urals, and Siberia. Two specimens examined from Japan identified as S. dyozankeanus (male) and S. ohdeyamanus (female) by K. Mitai proved to be S. crassus. Description, figures (Tsuneki 1983, 1984), and redescription (Mitai & Tadauchi 2013) of S. dyozankeanus and S. ohdeyamanus also indicate identity with S. crassus. For this reason we propose S. dyozankeanus and S. ohdeyamanus as new junior synonyms of S. crassus.
