System

The Schwarzgefleckte Palm Lanzenotter fer de lance is one of seven species of palm Terciopelos ( Bothriechis ) and thus the American pit vipers. Until a few years the entire genus was assigned to the American Terciopelos ( Bothrops ). After the revision of the former wholesale genus by Burger in 1971 and Steven D. Werman 1992, the assignment was made as a separate genus.

Within the Palm Terciopelos, the Schwarzgefleckte Palm Lanzenotter is a very basal sort incurred as the sister species of all other Palm Terciopelos with the exception of the Eyelash viper ( B. schlegeli ) is considered:

Ophryacus undulatus (as sister species )

Eyelash viper ( B. schlegelii )

Schwarzgefleckte Palm Lanzenotter (B. nigroviridis )

Rowley's Palm Lanzenotter (B. rowleyi )

Gelbgefleckte Palm Lanzenotter (B. aurifer )

Green Yellow Palm Lanzenotter (B. lateralis)

Two-color Palm Lanzenotter (B. bicolor)

Marchs Palm Lanzenotter (B. marchi )

Snake venom

Venoms of pit vipers contain a mixture of enzymes, low molecular weight polypeptides, metal ions and other, in their function so far poorly understood components. Just as diverse are the effects of these toxins. As with all species of the genus, the venom of the black-spotted Palm Lanzenotter has accordingly tissue destructive and neurotoxic components.
