| 摘 要： | 2021年3月在大连进行潮间带生物调查时采集到2个裸鳃类标本,经鉴定发现为欧氏针盘海牛Diaulula odonoghuei (Steinberg, 1963),为中国新记录属和新记录种。在研究中对其进行了活体拍照,利用光学显微镜和扫描电子显微镜对其外部形态和内部解剖特征进行了观察。此外,测定了这两个标本的COI、16S rRNA和H3基因序列,将测得的基因片段与GenBank数据库中的针盘海牛属Diaulula的同源序列进行对比分析,构建了针盘海牛属的系统发育树。欧氏针盘海牛在我国沿海的发现,进一步丰富了中国海软体动物的物种多样性研究。

| Abstract: | During an investigation of the intertidal zone of Dalian, China, two nudibranch sea slugs were sampled. Morphological observations of the specimens suggest that they belong to Diaulula odonoghuei (Steinberg, 1963). The genus and species are both new to Chinese waters. In this study, the specimens were photographed alive, and its externally morphology and internal anatomy were studied using light and scanning electron microscopies. Phylogenetic trees based on two mitochondrial (COI, 16S rRNA) and nuclear (H3) genes using the Bayesian inference and maximum likelihood were reconstructed and analyzed. The discovery of Diaulula odonoghuei (Steinberg, 1963) further expand the knowledge on the species diversity of molluscs in China seas. |
