Original combination (type locality: Seoul, Korea, female type in the Museum fuer Naturkunde, Berlin, Germany). Bolbelasmus coreanus (Kolbe, 1886): Cartwright 1953 : 97 (generic combination); Krikken 1977 : 288 (notes; diagnosis; illustration); Kim 2000 : 45 (diagnosis; collecting records); Li et al. 2008 : 480 (redescription, illustrations, collecting records, distribution, remarks); Kral , Loebl and Nikolajev 2006: 83 (catalog, subgenus Bolbelasmus Kolbeus ); Nikolajev, Kral and Bezdӗk 2016: 33 (catalog, subgenus Bolbelasmus Kolbeus ). Kolbeus coreanus (Kolbe, 1886): Boucomont 1911 : 335 (generic combination); Boucomont 1912 : 17 (catalog); Boucomont and Gillet 1921 : 72 (record to Taiwan; diagnosis); Miwa 1930 : 164 (catalog); Miwa 1931 : 276 (catalog); Miwa and Chujo 1939 : 30 (catalog); Paulian 1945 : 42 (diagnosis; figures; distribution). Bolbelasmus kurosawai Masumoto, 1984: 76; Li et al. 2008 : 481 (junior synonym). Bolboceras conicifrons Fairmaire, 1896: 82; Boucomont and Gillet 1921 : 72 (junior synonym). Distribution. Korean Peninsula; China (Anhui, Zhejiang, Kweichow, Szechuan, Yunnan); Taiwan. Remarks. The detailed distribution of B. coreanus in China requires further investigation, particularly those from southwestern areas. Based on a large number of Bolbelasmus specimens recently collected from Yunnan and neighboring areas, we found no representatives of B. coreanus among them. Therefore, we reserve a decision about whether B. coreanus occurs in Yunnan, Thailand and India, as recorded by Krikken (1977) . Voucher specimens from the areas mentioned above are required.
