Abstract

During an investigation of nudibranch gastropods in the Yellow Sea, several specimens were collected from the intertidal zone of Qingdao, Shandong Province, China. Morphological observation of their external and internal anatomy revealed that they represent an undescribed species belonging to the genus Anteaeolidiella M. C. Miller, 2001. This new species, Anteaeolidiella decorus sp. nov., can be differentiated from other congeners by both external morphology and internal anatomy. Phylogenetic analyses of two mitochondrial (COI, 16S rRNA) and a nuclear (H3) gene using Bayesian inference, maximum likelihood analysis, and species delimitation analyses also support the separation of Anteaeolidiella decorus sp. nov. from its congeners.

摘要

在对黄海裸鳃类软体动物的调查中，从中国山东省青岛市的潮间带采集到了几个标本。对其外部和内部解剖结构的形态观察表明，它们代表了一个未被描述的种，属于 Anteaeolidiella M. C. Miller, 2001 属。这个新种，Anteaeolidiella decorus sp. nov.，可以通过外部形态和内部解剖结构与其他近缘种区分开来。基于贝叶斯推断、最大似然分析和物种界定分析的两种线粒体（COI、16S rRNA）和一种核（H3）基因的系统发育分析也支持将 Anteaeolidiella decorus sp. nov. 从其近缘种中分离出来。
