Atheris chlorechis is a viper species found only in the forests of West Africa.

[5] Atheris chlorechis venom can lead to major systemic envenoming, shock, blood loss due to coagulopathy, and renal failure.

[3] Adults have a uniform light green ground color, overlaid with a series of faint yellow, roughly paired spots running dorsally along the length of the body and about 2.5 cm (about 1 in) apart.

[3] Newborns are tan-brown in color, but this changes to a yellow-green hue with irregular dark spots within 24 hours.

[8] Atheris chlorechis is found in West Africa from Sierra Leone through Guinea, Liberia, Ivory Coast, and Ghana to southern Togo.
