is characterized by the presence of (RS+M)b in the fore wing, a broad stigma, concealed labrum, complete absence of notaulus, complete or nearly complete absence of sternaulus, and absence of an occipital carina.

Opius bellus is closely related to Opius (Bellopius) hirtus Fischer, but the head is dark in hirtus. Opius bellus and related species are characterized by a strong median carina on the propodeum (Fig. 4) relative to some of the other species currently placed in Bellopius.
