Venomous! Echis carinatus aliaborri DREWES & SACHERER 1974 has been referred to E. varia by CHERLIN & BORKIN 1990. CHERLIN 1984 and 1990 treats E. sochureki as valid species and erects the subgenus Turanechis for it. E. multisquamatus is considered as valid species by some authors (KHALIKOV, pers. comm.). Pauwels & Meirte (1996) cite Chabanaud (1917) who mentions Echis carinatus from Gambia. JOHANN (1981) reports C. carinatus from Algeria. Based on protein sequence data Okuda et al. (2001) suggest to elevate E. c. sochureki to species status.
