Walterinnesia aegyptia
''Walterinnesia'' is a genus of venomous elapid snake, also known as the Desert Black Snake or Desert Cobra.〔(ITIS (Desert Black Snake) )〕 It was long considered to be the only species within the genus ''Walterinnesia''. However, it was recently found that the eastern populations actually represent a different species, ''W. morgani''.〔Nilson, G. & N. Rastegar-Pouyani (2007) ''Walterinnesia aegyptia'' Lataste, 1887 (Ophidia: Elapidae) and the status of ''Naja morgani'' Mocquard 1905. Russian Journal of Herpetology, 14: 7-14.〕 ''W. aegyptia'' is entirely black in color, and has highly shiny scales. ''W. morgani'' differs in having a juvenile pattern of reddish crossbars on the back, and lower average ventral and subcaudal scale counts.〔
