Diagnosis. This widespread species is variable in a number of characters, including body length, the size of the preocellar pit, and the presence of a submarginal ridge on T1. This species is colored dark brown to black. As in O. turneri   , 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 O. coracinus   due to the congruence of other characters and the relatively small series that they comprise. Th is species is quite similar in appearance to O. turneri   , and can be reliably separated by the subequal size of the mandibular teeth.

Etymology. The epithet coracinus   , meaning “ravenlike”, refers to the color of this species.

Comments. One specimen from the Central African Republic shares the majority of its characters with O. coracinus   but it has yellow antennomeres 2-6, and yellow femora, tibiae, and tarsomeres. 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 O. coracinus   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).
