Phylogenetic placement of Ostiactis pearseae. Phylogenetic reconstruction resulting from maximum likelihood analysis using PhyML (RaxML results not shown, but congruent) of the concatenated dataset of three mitochondrial (12S rDNA, 16S rDNA, COIII) and two partial nuclear markers (18S and 28S rDNA). Dotted boxes indicate actiniarian suborders; colored triangles and green box indicate actiniarian superfamilies; empty boxes and arrows indicate relevant actiniarian clades. Position of Ostiactis pearseae specimens from Pescadero Basin vent communities is highlighted in the orange box; the position of an additional sea anemone (unidentified morphospecies Kadosactinidae ‘sp.B’) is indicated by the light orange box. Bootstrap resampling values are indicated by black circles; only support values > 80% are shown
