Abstract

In the present study, a new species of a rarely encountered genus Hartman, 1965, , is described based on specimens collected from slope depths of the northern South China Sea. It is characterized by the presence of branched branchiae and heavy acicular spines in the anterior chaetigers, and is morphologically distinct from the other species of the genus in the shape of the anterior margin of the prostomium, the number of neuropodia with nipple-like projections distally, and the segment annulation. Four gene fragments of the new species were sequenced, comprising 16S rRNA, 18S rRNA, 28S rRNA, and histone H3. This study represents the first report of in the South China Sea.

摘要

在本研究中，基于从南海北部斜坡深处采集的标本，描述了一个1965年哈特曼属中罕见的新物种。它的特征是具有分支鳃，且前部刚节中有粗大的针状刺，在口前叶前缘形状、具有远端乳头状突起的腹足节数量以及体节环纹方面，其形态与该属的其他物种明显不同。对该新物种的四个基因片段进行了测序，包括16S rRNA、18S rRNA、28S rRNA和组蛋白H3。本研究是该物种在南海的首次报道。
