A–9G) are amoeboid in shape, of variable size, (6.3–8.8 x 8.9–16.9 µm) characterized by one or several large &quot;pockets&quot; formed by junction of long and thin pseudopodial extensions engulfing portions of the mesohyl that often include bacteria. As the size and the number of pockets progressively increase, the volume of the cytoplasm decreases until it becomes a thin layer surrounding a nucleolated nucleus (1.7–2.1 x 2.2–3.3 µm). The final content of the pockets has the same density as the mesohyl. The cytoplasm contains phagosomes and abundant electron dense and electron translucent small inclusions.

Phylogenetic positions of Halisarca magellanica and H. desqueyrouxae sp. nov. Shown is a posterior majorityrule consensus tree obtained from the Bayesian analysis of cox 1 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." httpUri="https://zenodo.org/record/214976/files/figure.png" pageId="14" pageNumber="515">Fig. 19</figureCitation>
