Ten species of the genus Bothrops occur in Bolivia and Peru: B. jonathani, B. andianus, B. sanctaecrucis, B. mattogrossensis, B. pictus, B. barnetti, B. brazili, B. osbornei, B. atrox, and B. moojeni. The systematic relationships of some of these species remain unclear and a few of them have not been included in cladistic analyses yet. Internal and external morphological characters were recorded during the revision of specimens from Bolivian and Peruvian collections, and the relationship between species was analyzed through cladistic methods. The relative importance of some characters and the possibility that the phylogeny of this species group helps to understand the historical biogeography of the genus are discussed.
