FIGURE 19 in Integrative taxonomic re-description of Halisarca magellanica and description of a new species of Halisarca (Porifera, Demospongiae) from Chilean Patagonia

FIGURE 19. Phylogenetic positions of Halisarca magellanica and H. desqueyrouxae sp. nov. Shown is a posterior majorityrule consensus tree obtained from the Bayesian analysis of cox1 sequences under the "mixed" model of nucleotide substitutions with 4 gamma categories in Mr. Bayes. The tree was drawn in FigTree (http://tree.bio.ed.ac.uk/software/figtree/). The number at each node represents the Bayesian posterior probability. Sequences from five specimens of H. magellanica, seven specimens of H. desqueyrouxae sp. nov. and 13 specimens of Chondrilla aff. nucula are shown as "collapsed" subtrees (triangles). The height of a triangle reflects molecular divergence among sequences it contains. No differences were found among sequences of H. magellanica or among sequences of H. desqueyrouxae sp. nov. Sequences of Chondrilla aff. nucula are 0–1.2% different.
