Chelostoma are longer than most Osmini because of their elongated thorax. Identifying this genus means noticing where the tegula lie in relation to the thorax. Pretend you are drawing a "+" on the thorax. The ends of Chelostoma tegula (that part closest to the wings) are about midway as shown in this photo whereas in other Osmini the tegula ends are lower on the thorax as shown in this photo
