Figures

Figure 1. Bayesian phylogenetic tree based on SSU and COI sequences of the family Cyphoderiidae.At each node posterior probability values (Bayesian analysis) and bootstrap values (Maximum Likelihood analysis) are represented.The colours represent the molecular clades. GenBank accession codes are given on the tips. Species names correspond to the taxonomic assignation of the organisms based on morphology for each lineage.

Figure 3. Dichotomous key of the family Cyphoderiidae.New genera are in bold with their respective shell outline drawing (50 μm scale bar), scale arrangement under SEM (grey box with 10 μm scale bar), and shell outline under light microscopy (orange box) in order to differentiate them. (A) Cyphoderia; (B) Oleiformis gen. nov.; (C) Ichthyosquama gen. nov.: (D) Knarr gen. nov., (E) Psammoderia gen. nov.

Figure 4. SEM images of C. ampulla and the different UCS from the Cyphoderiagenus. Insets show the typical habitat for each organism.The original drawing of C. ampulla from Ehrenberg, 1840 is shown top right.The white bars represent a scale of 10 μm and the black one 50 μm for each organism.
