Note.—List of the lophotrochozoan-specific homeobox gene clades found and their phylogenetic origin. Clades show varying levels of statistical support in gene trees. This list also includes a clade CG11294 defined in a previous study (Simakov et al. 2012), here named PRD Clade III. “—” indicate putative groups without monophyletic support.
