摘要

最近对蟒蛇(Serpentes: Boidae: Eunectes)的一次修订,描述了一个新的绿蟒物种,引起了广泛的关注,但由于证据不足和命名错误,也引发了相当大的争议。在此,我们以这本有问题的出版物为例,说明(i) 强调影响物种划分的常见问题,尤其是过度依赖线粒体 DNA 数据,并重申最佳做法;(ii) 重新分析现有的蟒蛇数据,以确定当前的真实知识状况,并强调进一步研究的方向;(iii) 分析该属的命名历史和现状。虽然我们的分析揭示了绿蟒和黄蟒在形态上的显著差异,但还需要进行更密集的取样和对信息丰富的核标记进行分析,才能对Eunectes进行有意义的物种划分。追溯命名类型的历史可以确定特立尼达岛是林尼厄斯(Boa murina Linnaeus, 1758)的模式产地,并确定该物种的现存模式。最后,我们强调期刊和作者都有责任确保已发表的分类学研究成果符合证实新物种描述所需的证据要求,并确保物种的命名符合动物学命名规则。

How not to describe a species: lessons from a tangle of anacondas (Boidae: Eunectes Wagler, 1830)
A recent revision of the anacondas (Serpentes: Boidae: Eunectes), with the description of a new species of green anaconda, generated extensive publicity, but also provoked considerable controversy due to inadequacies of the evidence used and errors in nomenclature. We here use the case of this problematic publication to: (i) highlight common issues affecting species delimitations, especially an over-reliance on mitochondrial DNA data, and reiterate best practices; (ii) reanalyse the data available for anacondas to establish the true current state of knowledge and to highlight lines of further research; and (iii) analyse the nomenclatural history and status of the genus. While our analysis reveals significant morphological variation in both green and yellow anacondas, denser sampling and an analysis of informative nuclear markers are required for meaningful species delimitation in Eunectes. Tracing the history of name-bearing types establishes Trinidad as the type locality for Boa murina Linnaeus, 1758 and allows identification of the extant lectotype for the species. Finally, we emphasize the responsibility of both journals and authors to ensure that published taxonomic work meets the burden of evidence required to substantiate new species descriptions and that species are named in compliance with the rules of zoological nomenclature.

期刊介绍: The Zoological Journal of the Linnean Society publishes papers on systematic and evolutionary zoology and comparative, functional and other studies where relevant to these areas. Studies of extinct as well as living animals are included. Reviews are also published; these may be invited by the Editorial Board, but uninvited reviews may also be considered. The Zoological Journal also has a wide circulation amongst zoologists and although narrowly specialized papers are not excluded, potential authors should bear that readership in mind.
