Abstract In this study we report the first finding of the red alga Acanthosiphonia echinata in the Mediterranean Sea. Specimens were identified using the DNA barcoding method and, in particular, the plastidial rbcL and the mitochondrial COI-5P markers. This species has been considered to be restricted to the western Atlantic and was reported in blooms from North Carolina to South Carolina. In 2015 the introduction of this species in Southeast Asia (Indonesia) was reported. Probably this taxon was introduced in the Mediterranean Sea from Indonesian populations associated with seaweed farming activities or hull fouling, via the western Atlantic-Mediterranean-Indonesia ship route.

Acanthosiphonia echinata（Rhodomelaceae，Rhodophyta）在地中海的首次记录，分子和形态特征

摘要 在这项研究中，我们报告了地中海红藻 Acanthosiphonia echinata 的首次发现。使用 DNA 条形码方法鉴定样本，特别是质体 rbcL 和线粒体 COI-5P 标记。该物种被认为仅限于西大西洋，据报道，从北卡罗来纳州到南卡罗来纳州都有大量繁殖。2015 年，该物种被引入东南亚（印度尼西亚）。可能该分类群是从与海藻养殖活动或船体污垢相关的印度尼西亚人口通过西大西洋-地中海-印度尼西亚航线引入地中海的。
