Remarks. Prior to the untimely passing of the third author, he sent the first author a comprehensive list of material that he had examined and identified, mainly originating from MRAC and CAS. We were able to confirm most of the records, as initial morphospecies photo plates sent to him to aid identification corresponded to the geographical limitations seen amongst other material examined by the first author, e.g. O. calceata in West Africa versus O. radiata in southern Africa and O. milloti in western Kenya . However, some specimens from Central Africa fall into a potential convergence zone between these three species (Fig. 102), and we thought it risky to try and attribute them to either of these three species at this point. We include them here as undetermined specimens to record the occurrence of the genus in these four countries, but these specimens should be reexamined when they are available again to clarify their identification and provide new distribution data for the particular species.
