Lachesis (genus) - Taxonomy

Taxonomy

Campbell and Lamar (2004) also recognize a fourth species, L. acrochorda (García, 1896), referring to it as the Chochoan bushmaster. It is found in western Panama and northwestern Colombia and Ecuador. Its evolutionary relationships are not certain, but Lachesis acrochorda is thought to be closer to the South American bushmaster L. muta than to the two Central American species L. stenophrys and L. melanocephala.
