FIGURE 5 in Integration of nuclear and mitochondrial gene sequences and morphology reveals unexpected diversity in the forest cobra (Naja melanoleuca) species complex in Central and West Africa (Serpentes: Elapidae)
FIGURE 5. Naja (Boulengerina) guineensis sp. nov. Left and top right: holotype, MNHN 1921.0485, dorsal and ventral view and side view of head. Note extensive mottling of throat and anterior ventral side and limited posterior extent of lighter ventral markings. Bottom right: live adult specimen measuring approximately 200 cm total length, from Sekondi-Takoradi, Western Region, Ghana, displaying dark suffusion of throat and anterior venter (not preserved; photo L. Chirio).

FIGURE 4. Ordination of individual specimens and OTU centroids of four of the mitochondrially defined candidate species of the N. melanoleuca complex along the first two canonical variates. CS5-peroescobari was omitted due to the small available sample size. Canonical variates 1 and 2 account for 57.9 and 22.8% of total variance, respectively. Enlarged symbols indicate OTU centroids.

FIGURE 8. Naja (Boulengerina) melanoleuca. Adult specimens from Yaoundé, Cameroon (left—photo J.-F. Trape) and Tsibilé, Gabon (right—photo L. Chirio). Note the diffuse but distinct hood mark that is often present in this species, and the combination of broad main bands and narrow accessory bands on the ventral side.

FIGURE 9. Naja (Boulengerina) subfulva. Variation in colour and pattern. Top left: specimen from Kakamega, western Kenya, illustrating the typically deep black and white specimens with strong facial markings from the periphery of Lake Victoria. Bottom left: specimen from Chuka, Mount Kenya, Kenya, illustrating an extreme of the brown forebody and reduced facial pigmentation typical of the species in much of its range. Photos W. Wüster, courtesy Royjan Taylor / Bio-Ken snake farm live collection, Watamu, Kenya. Right: specimen from Bamenda, Cameroon, representing the form described by Stucki-Stirn (1979) as Naja melanoleuca aurata. Note the indistinct ventral bands and the lack of accessory ventral bands, as is typical of this species. Photo J.-F. Trape.

FIGURE 1 in New and noteworthy Melanoleuca (Pluteaceae) from Pakistan
FIGURE 1. Molecular phylogenetic analysis of Melanoleuca spp. based on ITS sequences. The evolutionary history was inferred by the Maximum Likelihood method based on General Time Reversible model. The tree is drawn to scale, with branch lengths measured in the number of substitutions per site. The analysis involved 61 nucleotide sequences. There were a total of 886 positions in the final dataset. Pluteus salicinus was chosen as outgroup. Sequences generated during this study are marked with z.
