摘要

Monotaxis heterodon (Bleeker, 1854)广泛分布于印度洋-太平洋，但据报道Monotaxis grandoculis (forssk l, 1775)是该地区Monotaxis的唯一种。在南海美济礁泻湖水域采集了4只异齿海蛸标本。通过形态计量学研究，证实了南海海域中异齿海鞘的存在，并将其与大粒海鞘彻底分离。此外，采用DNA条形码对标本进行分类。异齿田鼠组内平均遗传距离为0.24个百分点，与大粒田鼠组间平均遗传距离为8.71个百分点。系统发育分析证实南海泻湖海域存在异齿藻。本研究将有助于该属在南海的物种鉴定。

First record of Monotaxis heterodon (Actinopterygii: Perciformes: Lethrinidae) from the lagoon waters of Mischief Reef, South China Sea

Monotaxis heterodon (Bleeker, 1854) is widespread in the Indo-Pacific Ocean, however, it was reported that Monotaxis grandoculis (Forsskål, 1775) was the single species of Monotaxis in this area. We collected four M. heterodon specimens from the lagoon waters of Mischief Reef in South China Sea. A morphometric study was taken to confirm the occurrence of M. heterodon in the seawaters of the South China Sea and thoroughly separate them from M. grandoculis. In addition, DNA barcoding was taken for the classification of specimens. The mean genetic distance within M. heterodon group was 0.24 percentage points, group mean distance between M. heterodon and M. grandoculis was 8.71 percentage points. The phylogenetic analysis confirmed the existence of M. heterodon in the lagoon waters of the South China Sea. This study will contribute to species identification within this genus distributed in the South China Sea.
