Abstract

Background: The genus Nebo has been identified as a medically important scorpion species distributed across Arabia and the Middle East. However, its taxonomic status remains unclear.

Aim: The molecular phylogeny of two Nebo species from Saudi Arabia and comparative sequences from Palestine is presented based on the mitochondrial cytochrome oxidase subunit I (COI) gene.

Methodology: Scorpion specimens were collected from two different localities, mainly the Southern part of Saudi Arabia. Then, DNA was extracted, amplified using invertebrate universal primers, and sequenced to identify the COI gene. The obtained sequences were analyzed, and phylogenetic trees based on maximum parsimony, neighbor-joining, and Bayesian inference were constructed.

Results: The inferred phylogeny indicates the monophyletic status of the family Diplocentridae and its subfamily Nebinae and Diplocentrinae. Also, the phylogenetic analyses support the existence of interspecific and intraspecific variations among/ within Nebo hierichonticus and Nebo yemenensis which may indicate distinct species.

Conclusion: Further morphological studies with additional specimens from the Arabian Peninsula may reveal possible undiscovered and cryptic species.

沙特阿拉伯和中东Nebo属两种天蝎的系统发育关系。

背景:Nebo属已被确定为一种重要的医学蝎子，分布在阿拉伯和中东地区。然而，其分类地位尚不清楚。目的:基于线粒体细胞色素氧化酶亚基I (COI)基因，介绍了来自沙特阿拉伯和巴勒斯坦的两个尼波人的分子系统发育和比较序列。方法:蝎子标本采集于两个不同的地点，主要集中在沙特阿拉伯南部。然后提取DNA，用无脊椎动物通用引物扩增，测序鉴定COI基因。对得到的序列进行分析，构建了基于最大简约性、邻居连接和贝叶斯推理的系统发育树。结果:推断出的系统发育表明了双中心科及其亚科Nebinae和双中心科的单系地位。此外，系统发育分析也支持了尼布猿和尼布猿之间存在种间和种内变异，这可能表明它们是不同的物种。结论:对来自阿拉伯半岛的其他标本进行进一步的形态学研究可能会揭示可能未被发现的和隐藏的物种。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
