Diagnosis	Diagnosis: “Race de Cordylus vittifer différant de la forme typique par son plus grand nombre de rangées longitudinales d'écailles dorsales: 26-28 au lieu de 20-24 et la rostrale moins large (hauteur comprise 2,34 à 2,32 fois dans sa largeur au lieu de 3 à 4 fois)” (Laurent 1964).
Comment	Distribution: see map in GREENBAUM et al. 2012. Cordylus v. machadoi was originally distinguished from other C. vittifer on the basis of its greater numbers of longitudinal dorsal scale rows (26–28 versus 20–24) and a narrower rostral scale (2.32–2.34 times wider than deep versus 3–4 times wider). Reichenow (1887), in his original description of Zonurus vittifer (Fig. S2), reported only 20–22 longitudinal dorsal scale rows and did not mention the size or shape of the rostral, and it therefore seems that Laurent (1964) was referring to Loveridge (1944a, see table on p. 15 in Bates et al. 2023) and possibly also FitzSimons (1943) when comparing machadoi to vittifer.
Etymology	Named after Dr. A. de Barros-Machado, who collected the type in Angola.
