The Neotropics harbour a spectacular amount of biodiversity, but many of these species remain to be discovered and placed into the tree of life. In the neotropical snake genus Philodryas, the systematics of these rear-fanged snakes has been controversial and debated in recent years. Here, we combine published datasets with new morphological (scale microdermatoglyphics, osteology, pholidosis and genital features) and molecular (mitochondrial and nuclear) data to reassess the phylogenetic positioning of rear-fanged snakes within the tribe Philodryadini. We identified putative synapomorphies and pronounced morphological variation in hemipenial features. Our results suggested a need to reclassify many species in order to clarify some relationships within the Philodryas radiation. We also redefined Philodryadini by resurrecting three genera and naming a newly discovered species.

树上的幻影:综合分类法支持重新评估后fang蛇的分类(Dipsadidae:Philodryadini)

新热带地区拥有数量惊人的生物多样性,但其中许多物种仍有待发现并置于生命之树中。在新热带蛇类Philodryas中,这些后fang蛇的系统学在近年来引起争议和争论。在这里,我们将已发布的数据集与新的形态学(鳞状微皮雕,骨病学,卵磷脂和生殖器特征)和分子(线粒体和核)数据结合起来,以重新评估后方蛇在费洛德亚迪尼部落中的系统发育定位。我们确定了半突特征的假定的突触和明显的形态变异。我们的结果表明有必要对许多物种进行重新分类,以阐明费城地区内的某些关系。辐射。我们还通过复活三个属并命名新发现的物种来重新定义Philodryadini。
