Bothrops属的物种。L.与响尾蛇亚科其他属相比，在生态学和地理学上都有很大的变化。与大而多变的类群分裂成更小的、在生态学和表型上更紧密的属的趋势相反，Bothrops属仍然保持着物种化。此外，以前的系统发育分析发现Bothrops是并列的Bothriopsis属。分类学上存在将Bothriopsis与Bothrops合群，以及将Bothrops分成更小属的争论，但分类修订的最大障碍是不完整的系统发育信息。我们提出了Bothrops，Bothriopsis，Bothrocophias的85个字符的形态和2343 bp的四个线粒体基因区的基础上，和显着更大的分类覆盖率比以前的研究。合并后的数据提供了更好的支持独立的数据集，并支持Bothrops内离散物种群的存在。这些群体的单系性和独特性在属的水平上值得承认，我们提出了一个新的分类安排，以反映这些发现。(C)2009伦敦林奈学会，林奈学会动物学杂志，2009年，156，617-640。
Species in the genus Bothrops s. l. are extraordinarily variable in ecology and geography, compared with other genera in the subfamily Crotalinae. In contrast to the trend of splitting large and variable groups into smaller, more ecologically and phenotypically cohesive genera, the genus Bothrops has remained speciose. In addition, previous phylogenetic analyses have found Bothrops to be paraphyletic with respect to the genus Bothriopsis. Taxonomic arguments exist for synonymizing Bothriopsis with Bothrops, and for splitting Bothrops into smaller genera, but the greatest hindrance to taxonomic revision has been incomplete phylogenetic information. We present a phylogeny of Bothrops, Bothriopsis, and Bothrocophias based on 85 characters of morphology and 2343 bp of four mitochondrial gene regions, and with significantly greater taxonomic coverage than previous studies. The combined data provide improved support over independent datasets, and support the existence of discrete species groups within Bothrops. The monophyly and distinctness of these groups warrant recognition at the generic level, and we propose a new taxonomic arrangement to reflect these findings.
