FIGURE 2. Phylogenetic tree inferred by Bayesian analysis (BI) and maximum likelihood (ML) based on concatenated dataset of COI, 16S and H3 genes. Numbers adjacent to nodes refer to BI posterior probability (PP> 0.5) and ML bootstrap scores (BS> 50). Vertical green and blue bars indicate the results of ABGD and ASAP species delimitation, respectively.

Figure 2 in A stomach plate to divide them all: a phylogenetic reassessment of the family Tritoniidae (Nudibranchia: Cladobranchia)

Figure 2. Bayesian phylogenetic tree based on the concatenated molecular data (COI + 16S + H3) of Tritoniidae (sensu Odhner 1963). Outgroup taxa are depicted in grey. Tritoniidae genera are independently coloured, and branches with several replicates for each species hypothesis were collapsed for clarity. Names in bold are species which sequences were generated for this study with the number of sequenced specimens showed in brackets. PP are shown right/top and BS leħ/boưom. Unsupported branches are not labelled. Green circles indicate maximum support by both analyses. Solid vertical bars indicate specimens grouped as species entities based on COI dataset. Empty vertical bars indicate the specimens grouped as species based on the 16S dataset.
