摘要

本文根据在南海北部坡深采集的标本，描述了一个罕见的硬壳藻属（Sclerobregma Hartman, 1965）的新种Sclerobregmananhaiensis sp. nov.。它的特征是在前面的毛虎中存在分支的分枝和重针状刺，在形态上与该属的其他物种不同，包括口前缘的形状，远端有乳头状突起的神经足的数量和节环。对新种的4个基因片段进行了测序，包括16S rRNA、18S rRNA、28S rRNA和组蛋白H3。本研究首次报道了南海的硬藻。

A new species of a rarely encountered genus Sclerobregma Hartman, 1965 (Annelida, Scalibregmatidae) from the deep South China Sea.

In the present study, a new species of a rarely encountered genus Sclerobregma Hartman, 1965, Sclerobregmananhaiensis sp. nov., 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 Sclerobregma in the South China Sea.
