Abstract
Based on morphology, biogeography, biology, and the results of a molecular phylogenetic analysis, a new species of Dasypeltis is described from Harenna Forest in the southern Somalian plateau in Ethiopia. It is a medium-sized member of the genus (females up to 92 cm total length, males up to 58 cm), usually uniformly black dorsally but occasionally light brown with a dense and somewhat irregular pattern of narrow brown saddles and vertically elongate lateral markings, sometimes forming bands across the back, and small white spots and streaks, or reddish-brown with indistinct darker dorsal and lateral markings. Interstitial skin is light grey, appearing bluish in adults. Infralabials, chin shields, gulars, and 20–62 anterior ventral plates (medially) are mostly white, the other plates being ash-grey or black in colour. Scales in the first row of dorsals on either side of the body are smooth or almost smooth; those of the second row are weakly keeled; other dorsal scales are moderately keeled with two apical pits each. Pairwise genetic distance between the new species and its closest congener, D. atra, is similar to or greater than the distances between some long-recognised species in the genus. The new species is also geographically and ecologically isolated from closely related congeners.
