Stelis is a genus of megachilid cleptoparasites. They are stocky but elongate, evenly wide down the length of their bodies, and often with relatively sparse hairs. As cleptoparasites, females do not have pollen carrying hairs on their bodies. With the exception of one relatively widespread species, Stelis are generally not often encountered.
