Historically, what species was *Naja nigricincta* considered a subspecies of before being split taxonomically?

Black-necked Spitting Cobra (*Naja nigricollis*)

For a considerable duration in taxonomic history, *Naja nigricincta* was not recognized as a distinct species but rather as a subspecies falling under the umbrella of the Black-necked Spitting Cobra, scientifically known as *Naja nigricollis*. This historical arrangement is common in taxonomy, where evolving research methods, particularly genetic analysis, reveal significant divergences previously overlooked based only on gross morphology. The revision resulting in *N. nigricincta* gaining independent species status was based on established differences in size, appearance (notably in the *woodi* subspecies), and geographical isolation, confirming evolutionary divergence within the *Naja nigricollis* species complex.
