Nubia [= Deram].
Has been treated as conspecific with O. finschii and hybridization between them recently recorded#R. Taxonomy complex, and several proposals have been offered. In one of commonest, races comprise four basic groups, each of which could possibly be treated as a separate species: “lugens group” (also including halophila and persica); “lugentoides group” (with boscaweni); “lugubris group” (with vauriei); and single-taxon “schalowi group” (sometimes included in “lugubris group”), although some commentators have suggested that both halophila and persica might be recognized as additional species#R#R#R. Differences between nearest-neighbour groups, however, are weak, even though total variation is high; consequently, new arrangements can overlap, e.g. the “lugentoides group” has been treated both as a species on its own and as a member of a separate species that includes the “lugubris group” and schalowi. What was previously considered black morph of nominate race recently described as separate race, warriae#R. Name syenitica, previously applied erroneously to NW African race of O. leucura, now known to represent member of present species, considered synonymous with nominate race by some authorities#R, but far more likely to be either a senior synonym of warriae or an independent (perhaps extinct) taxon#R. Recent analysis using mtDNA recommended species status for O. lugens, O. lugentoides and O. lugubris (this last with schalowi), but obtained no evidence from nuclear DNA#R; call made in HBW for integrative review involving also vocal, behavioural and ecological evidence still unanswered. Nine subspecies recognized.
