FIGURE 1. Maximum likelihood tree constructed from an 861-bp alignment of the mitochondrial gene msh1. Numbers above branches are bootstrap values. Labels indicate genus, species or specimen ID, and GenBank accession number. Representative species of family Primnoidae were used to root the tree. Mitochondrial gene order of Keratoisidinae differs from that of other octocoral taxa.
FIGURE 3 in Toward a revision of the bamboo corals: Part 3, deconstructing the Family Isididae
FIGURE 3. Midpoint rooted RAxML cladogram. Bootstrap values> 50 are shown at the nodes. Baysian posterior probability values>0.5 are shown below the node. The tree is based on a concatenated alignment of mtMutS-5', mtMutS-3', and 18S, and includes 61 total taxa (26 isidids). Clades with an articulated skeleton are marked with a large asterisk (*) on the branch. The type genus of the Isididae is indicated by the black rectangle and Isididae sensu lato are indicated by the purple rectangles. Light yellow circles indicate clades that have the "ancestral" mt genome arrangement (as defined by Brockman & McFadden, 2012). The dark blue circle indicates the clade that has the Keratoisidinae mt genome arrangement mapped by Brugler and France (2008). Only isidid mt genomes are mapped on the tree. Small asterisks (*) following taxon names indicate specimens used to test mt gene boundaries. The "S1 clade" of Keratoisidinae is the one with taxa Cladarisis sp. 1 and sp. 2.

The clades that include taxa currently classified as Isididae are indicated in bold font.
