Remarks. This species unlike O. armata never develops anything that resembles a felt line on the second metasomal sternite. This species, along with O. melicausa, has a tendency to develop a slight secondary mesosternal tubercle posterior to the primary one. Sometimes this can be unilateral (Ferguson 1967).
