(12 km N Darasun, Tura River); Yakutia (Amga, Michailovka, Khaptagai, Zhemkon, 75 km SE Yakutsk, Pilka River, Olekminsk); Amurskaya Prov. (Kundur, 20 km SW Fevralsk, Talakan); Primorskiy Terr. (Lazovskiy Nature Reserve, Anisimovka, Spassk, Kievka, Andreevka, Novokachalinsk, Blagodatnoe, Novovladimirovka, Lozovoi, Rudnaya Pristan, Preobrazhenie, Evseevka, Khorol); Khabarovsk Terr.

Distribution in Russia. European part ( Osytshnjuk et al. 1978), Tomsk. Prov., Kemerovo Prov., Khakasia Republic ( Konusova & Yanyushkin 2000; Konusova et al. 2007), *Altai Republic, Zabaikalskiy Terr., Yakutia, Amurskaya Prov., Primorskiy Terr., Khabarovsk Terr., Sakhalin, Kuril Islands (Kunashir) ( Kuwayama 1967).

General distribution. Transpalaearctic up to Kuril Islands; Japan (Hokkaido, Honshu, Tsushima) ( Ikudome 1989); China (Jilin, Xizang); all over Europe to 66° north, south to Greece; China (Xizang), Asia Minor, Caucasus.

Remarks. Until now Hylaeus confusus Nylander 1852 has been considered to be very common in the Russian Far East, but absent on the Japanese islands; in Japan, until now, only a similar species, H. monticola Bridwell 1919 , was recorded. We have now compared the taxa in question, using material from Russia and Japan that includes the type of H. monticola (3, type no 50734, NMNH Department of Entomology, Smithsonian Institution). It was also necessary to consider new insights on the taxonomy of the Hylaeus gibbus species-group provided by Straka & Bogusch (2011). The result is clear: the Japanese specimens belong to the common and widespread H. confusus Nylander.
