Abstract

The accurate assignment of cryptic larvae to species-level is a key aspect of marine ecological research and can be achieved through integrated molecular and morphological studies. A combination of two mitochondrial markers (COI and 16S) and a detailed morphological analysis was used to identify phyllosoma larvae of slipper lobster (Scyllaridae) species collected during a survey in the SW Indian Ocean. Two morphotypes were tentatively assigned to Acantharctus ornatus and Biarctus pumilus, both genera for which the larval morphology was unknown. Morphological revision of an adult specimen used to generate the putative A. ornatus sequences in GenBank revealed that it was misidentified and corresponds to B. dubius. The final phyllosoma stage of B. pumilus and subfinal and final stages of A. ornatus were described, clarifying prior misidentifications in the literature. Scyllarid biodiversity in the SW Indian Ocean is underestimated and sampling of deeper water layers is recommended to complete current knowledge of species and larval stages present in the region.

西南印度洋Acantharctus和Biarctus龙虾（甲壳纲：虾科）叶体幼虫的鉴定。

将隐蔽幼虫准确分配到物种水平是海洋生态学研究的一个关键方面，可以通过综合分子和形态学研究来实现。结合两种线粒体标记（COI和16S）和详细的形态学分析，鉴定了在西南印度洋调查期间收集的拖鞋龙虾（Scyllaridae）物种的叶状体幼虫。初步将两种形态类型分为圆腹蛛属和扁腹蛛属，这两个属的幼虫形态尚不清楚。在GenBank中，对一个用于生成假定的A.ornatus序列的成年标本进行形态学修正，发现它被误认，与B.dubius相对应。描述了B.pumilus的最终叶体阶段和A.ornatus的亚终末和终末阶段，澄清了文献中先前的错误鉴定。西南印度洋的珊瑚礁生物多样性被低估，建议对更深的水层进行采样，以完成该地区物种和幼虫阶段的现有知识。

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.
