This species is colored dark brown to black. As in <i>O. turneri</i>, the northern specimens tend to be blacker than those of Zimbabwe, but those from South Africa are typically very dark. Th e specimens from Cameroon, Nigeria, Yemen and some from Malawi have the preocellar pit conspicuously large (Fig. 17). Th ey are here treated as part of <i>O. coracinus</i> due to the congruence of other characters and the relatively small series that they comprise. Th is species is quite similar in appearance to <i>O. turneri</i>, and can be reliably separated by the subequal size of the mandibular teeth. <b>Etymology.</b> The epithet <i>coracinus</i>, meaning “ravenlike”, refers to the color of this species. <b>Link to distribution map.</b> <b> 22</b> <b>Material examined</b> .

We choose not to describe this as a new species due to the limited material and the possibility that the differences might be intraspecific. For this reason, this specimen is determined as <i>O. coracinus</i> but is excluded from the type series. Images of this specimen are available at the image database of Th e Ohio State University (purl.oclc.org/NET/ hymenoptera /specimage).
