摘要
尾蝎是蛛形纲的一目，通常被称为鞭蝎或鞭蝎。到目前为止，已知在巴西有两个属：1894年的Thelyphonellus Pocock和1894年的Mastigoproctus Pocock。研究人员利用线粒体和核分子标记对182个巴西直肠肌标本进行了形态学分析，并对42个标本进行了系统发育分析。在最大简约性、最大似然性和贝叶斯推理下进行系统发育推理。我们的研究结果表明，以前纳入Mastigoproctus的巴西种代表了两个不同的属，具有以下种和同义词：重新验证的Amauromastigon mello - leit, 1931，由A. maximus （Tarnani, 1889）组成，comb。11 . （=Mastigoproctus annectens Werner, 1916， M. butleri Pocock， 1894和M. perditus mello - leit, o, 1931）和Heptatarsus gen. nov.，由H. brasilianus （Koch, 1843）组成，梳子。11 . （= mastigoprous minensis mello - leit o, 1931）和H. custodioi sp. 11 .此外，我们在描述基于早期发育阶段标本的尾虫分类群时，敦促使用某些形态特征时要谨慎。ZooBank: urn: lsid zoobank.org:酒吧:9 ef06715 - 2 ba1 - 4616 a801 - 2239 dbe3dab4。
Molecular phylogeny and systematic revision of the Brazilian species of Mastigoproctus Pocock, 1894 (Arachnida: Uropygi: Mastigoproctinae).
Uropygi is an order of arachnids commonly known as vinegaroons or whip-scorpions. So far, two genera are known to occur in Brazil: Thelyphonellus Pocock, 1894 and Mastigoproctus Pocock, 1894. We examined the morphology of 182 specimens of Brazilian Mastigoproctus and sequenced 42 specimens for phylogenetic analyses, using mitochondrial and nuclear molecular markers. Phylogenetic inference was performed under maximum parsimony, maximum likelihood and Bayesian inference. Our results suggest that the Brazilian species previously included in Mastigoproctus represent two different genera, with the following species and synonymies: the revalidated Amauromastigon Mello-Leitão, 1931, composed of A. maximus (Tarnani, 1889), comb. nov. (=Mastigoproctus annectens Werner, 1916, M. butleri Pocock, 1894 and M. perditus Mello-Leitão, 1931), and Heptatarsus gen. nov., composed of H. brasilianus (Koch, 1843), comb. nov. (=Mastigoprotus minensis Mello-Leitão, 1931) and H. custodioi sp. nov. Also, we urge caution when using certain morphological characters when describing uropygid taxa based on specimens in early developmental stages.

期刊介绍：
Invertebrate Systematics (formerly known as Invertebrate Taxonomy) is an international journal publishing original and significant contributions on the systematics, phylogeny and biogeography of all invertebrate taxa. Articles in the journal provide comprehensive treatments of clearly defined taxonomic groups, often emphasising their biodiversity patterns and/or biological aspects. The journal also includes contributions on the systematics of selected species that are of particular conservation, economic, medical or veterinary importance.
Invertebrate Systematics is a vital resource globally for scientists, students, conservation biologists, environmental consultants and government policy advisors who are interested in terrestrial, freshwater and marine systems.
Invertebrate Systematics is published with the endorsement of the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and the Australian Academy of Science.
