Coelioxys species in the family Megachildae that are cleptoparasitic in the nests of genus Megachile bees. Since they 'steal' the pollen storehouse of their host by laying eggs in their nest, the Coelioxys do not have the abdominal hairs that we see on many members of that family. The female Coelioxys as a single point on the end of the abdomen and the males have teeth on the end of the abdomen.
