The best feature to separate this from the other eastern species, S. macer, is whether the propleuron (the swollen sclerite on the anterior edge of the thorax) is yellow (S. macer) or black with silvery hairs (S. angulatus). It looks silvery rather than yellow in this photo, but it is a bit difficult to tell.
