Table 2 in Ophryotrocha (Dorvilleidae, Polychaeta, Annelida) from deep-sea hydrothermal vents, with the description of five new species

Table 2. Minimum pairwise distances of COI sequences using uncorrected p-distances for 3 eastern Pacific new vent species of Ophryotrocha Claparède & Mecznikow, 1869, O. cf. akessoni Blake, 1985 and the closely related vent species O. jiaolongi Zhang, Zhou, Wang & Rouse, 2017. Bold values represent maximum intraspecific variation when known. Values for O. jiaolongi based on GenBank data reported in Zhou et al. (2022). The smallest interspecific distance found was between O. jiaolongi (Indian Ocean vents) and O. marinae sp. nov. (Gulf of California vents) with a minimum distance of 3.73% (and a maximum of 5.2% (underlined)). 1234561 O. jiaolongi Zhang, Zhou, Wang & Rouse, 20170.0112 O. cf. akessoni Blake, 19850.09240.01003 O. charlottae sp. nov.0.15590.11470.01944 O. kailae sp. nov.0.15410.15070.16420.00295 O. marinae sp. nov.0.03730.09400.14350.14500.00886 O. pruittae sp. nov.0.18610.19220.17770.16480.1959–表2. 基于未校正p距离的细胞色素c氧化酶亚基I（Cytochrome c Oxidase Subunit I, COI）序列最小成对距离，涉及3种东太平洋新型喷口生栖沙蚕属（Ophryotrocha Claparède & Mecznikow, 1869）新种、近似埃克森沙蚕（O. cf. akessoni Blake, 1985）以及亲缘关系较近的喷口生栖物种海龙沙蚕（O. jiaolongi Zhang, Zhou, Wang & Rouse, 2017）。加粗数值代表已知的种内最大变异值。海龙沙蚕的相关数值基于Zhou等人（2022）报道的基因银行（GenBank）数据。本次研究发现的最小种间距离出现于海龙沙蚕（印度洋喷口）和海生沙蚕新种（O. marinae sp. nov.，加利福尼亚湾喷口）之间，最小距离为3.73%，最大距离为5.2%（已下划线标注）。 1 海龙沙蚕（O. jiaolongi Zhang, Zhou, Wang & Rouse, 2017） 0.011 2 近似埃克森沙蚕（O. cf. akessoni Blake, 1985） 0.0924 0.0100 3 夏洛塔沙蚕新种（O. charlottae sp. nov.） 0.1559 0.1147 0.0194 4 凯拉沙蚕新种（O. kailae sp. nov.） 0.1541 0.1507 0.1642 0.0029 5 海生沙蚕新种（O. marinae sp. nov.） 0.0373 0.0940 0.1435 0.1450 0.0088 6 普鲁伊特沙蚕新种（O. pruittae sp. nov.） 0.1861 0.1922 0.1777 0.1648 0.1959–
