Types	Holotype: FMNH 134249, an adult female collected 24 March 1962 by Mr. Richard G. Japp (field number 1216).
Diagnosis	Diagnosis: A form of Crotaphopeltis differing from other species in the genus by having the upper postocular separated from the supraocular by a forward prolongation of the parietal, which· enters the orbit. Dorsal scale rows 17-17-13: both hotamboeia and degeni normally have 17-19-15 rows, although the former may have 21 rows anteriorly (ruiziensis Laurent, 1963), while tornieri normally has 17- 17 -15 rows (Loveridge, 1933). In barotseensis and degeni the dorsal scales are smooth, glossy and iridescent, but in hotamboeia and tornieri the posterior dorsals are feebly keeled. The head of barotseensis is narrower than in the other forms, with a high rostral and no expansion in the temporal region.
