Diagnosis. Naja senegalensis resembles all other members of the N. haje complex and differs from all other Naja in having a row of subocular scales separating the orbit from the supralabial scales. Naja senegalensis can be distinguished from other species of the N. haje complex through a combination of scale counts and the coloration of juveniles and adults. Comparative scale counts are given in Table 3. Naja senegalensis is distinguishable from N. haje through its higher neck scale row count: N. senegalensis normally has 25 dorsal scale rows around the neck, although some specimens have 23 or 27. By contrast, W. African N. haje have fewer neck scale rows (19–21 in five specimens from Niger, 21–23 in three specimens from Nigeria, 21 in one specimen from Tombouctou, Mali). In other parts of Africa, the majority of specimens also have 21 or fewer scale rows around the neck (Table 3). A cobra specimen from Djibouti, with 27 scale rows around the neck and 23 at midbody, tentatively assigned to the N. haje complex by Ineich (2001), appears to be a spitting cobra. Other scalation characters do not distinguish N. senegalensis from N. haje, although the new species tends to occupy the upper end of the spectrum of ventral scale counts in the complex (for more details see Table 3 and text in Trape et al. 2009). 
EtymologyThe name of the new species refers to the country of origin of the type series.
