Figure 8 in Biodiversity and phylogeny of Cocculinidae (Gastropoda: Cocculinida) in the Indo-West Pacific

Figure 8. Combined three-gene ML tree for 138 cocculinid specimens (1421 bp from cox1, 28S and H3). Nodal supports are shown as circles on nodes. Nodes supported by both bootstrap value (BS) ≥ 80% and posterior probability (PP) of ≥ 0.95 are shown in black circles; nodes supported by only BS ≥ 80% or PP ≥ 0.95 are shown in grey circles. Nodes with BS of <80% and PP <0.95 are not marked with a circle. Morphogroup types are plotted on the tree (Supporting Information, Table S2). Geographic distribution of each species is shown with filled square(s). Different shapes of rachidian tooth of radula are denoted with following symbols: X, obsolete;—, acuspate; circle with three spikes, multicuspid; circle with a single spike, unicuspid. Dotted squares, broad or narrow, indicate relative width of rachidian tooth. Asterisks represent nonmonophyletic morphogroups.

Figure 6 in Biodiversity and phylogeny of Cocculinidae (Gastropoda: Cocculinida) in the Indo-West Pacific

Figure 6. Maximum-likelihood tree based on cox1 dataset of cocculinids with results of species delimitation analyses. A, morphogroups MC, ME and MG. Numbers at tree nodes represent bootstrap values in percentages (values <70% not shown). Names of primary species hypotheses (PSHs) are followed by number of sequences determined (cox1 and 28S). Boxes for PSHs are highlighted in grey when differently delimited in ABGD and PTP analyses (numerals in boxes represent numbers of cox1 sequences; asterisks and plus signs for MA9–MA12 denote the same PSH detected by ABGD and PTP, respectively). 28S sequence monophyly and identity are also shown as empty boxes (NA: no data); cross marks (X) indicate non-monophyly or genotype shared with other PSHs. 'Shell morph.' denotes distinguishable forms of the shell with different numerals in each morphogroup (MA–MH). C1 for MC1–MC3, for example, means that the three PSHs are identical in conchological characteristics. Known bathymetric and geographic distributions and habitat are also provided for each PSH (bathymetric distribution—sampled depth ranges shown in lines, dotted lines represent the estimated distributed range; geographic distribution—AFR: Mozambique Channel, MAD: north Madagascar, TW: Taiwan and South China Sea, ECS: East China Sea, PHI: Philippines, JP: Japan, BIS: Bismarck Sea, SOL: Solomon Sea, COR: Coral Sea, VAN: Vanuatu, NC: New Caledonia, OTH: others, ME: Mediterranean, NZ: New Zealand, RS: Red Sea, AT: Atlantic, EP: East Pacific, WS: Weddell Sea; habitat—w: wood, l: leaf, b: bone, c: coral, e: egg case, vent*: hydrothermal vent area). Secondary species hypotheses (SSHs) are shown with generic and species names if available; those found from more than one area (northwestern Pacific, south-western Pacific, and Indian Ocean) are highlighted in grey.
