Annotated catalog of the series Spheciformes (Hymenoptera: Apoidea) from the Korean Peninsula

For future researchers, the Korean species of the series Spheciformes are catalogued. A total of 216 species in seven families are listed. Of these, species filtered according to four topics—taxonomically conflicting, highly questionable in Korean occurrence, not based on actual Korean material, and known only from North Korea—are listed and discussed.
