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)).
