Bothriechis is a genus of venomous pitvipers commonly called palm vipers or palm-pitvipers found predominantly in Mexico and Central America, although the most common species, B. schlegelii, ranges as far south as Colombia and Peru. All members are relatively slender and arboreal. The name Bothriechis is derived from the Greek words bothros and echis that mean "pit" and "viper" respectively. Ten species and no subspecies are currently generally recognized.
Species that belong to this genus typically reach lengths of 60–80 cm, while B. aurifer, B. bicolor and B. lateralis are known to grow to 1 m or more.
General characteristics include a sharply defined canthus rostralis, an unelevated snout, a rostral scale that is not as high as it is broad, and a prehensile tail that accounts for at least 15% of the body length.
The color pattern usually consists of a green ground color that may or may not include pale or dark markings. B. schlegelii is an exception to this rule.
Occurs in southern Mexico (southeastern Oaxaca and the northern highlands of Chiapas), through Central America to northern South America (Colombia, western Venezuela, Ecuador and northern Peru).
