Sapygidae 寡毛土蜂科
The Sapygidae are a family of solitary aculeate wasps. There does not seem to be a common English name, but club-horned wasps (translating the German name Keulhornwespen - in reference to the distinctive thickening of the antennae) seems as good a name as any, though various other groups of wasps also have clubbed or thickened antennae. They are generally black wasps, similar in appearance to some Tiphiidae, with white or yellow markings developed to various degrees.
