FIGURE 1 in In praise of subgenera: taxonomic status of cobras of the genus Naja Laurenti (Serpentes: Elapidae)

FIGURE 1. Schematic representation of the phylogeny of the genus Naja, indicating the subgenera recognised here. Redrawn from Wüster et al. (2007). Grey circles indicate nodes with ≥ 95% Bayesian posterior probability support. The position of taxa not included in that study was inferred from Slowinski & Wüster (2000 – N. atra, N. mandalayensis), Broadley & Wüster (2004 – N. annulifera) and Trape et al. (2009 – N. arabica, N. senegalensis). Naja christyi has never been included in a rigorous phylogenetic analysis. It is tentatively placed in this tree based on prior classification (Bogert, 1943).
