Fig. 2
Bayesian inference analysis of the concatenated dataset (COI + 16S + 28S). Constructed using MrBayes v3.2.7 software [30] under the following models of nucleotide evolution: GTR + I, F81 + I + G, GTR + G for the 1st, 2nd, and 3rd codons of the COI, and GTR + I + G for both 16S and 28S markers. Values at the nodes correspond to posterior probability (PP); asterisk (*) indicates well-supported nodes (PP > = 95%). Known and putative new Azorean Reteporella species are indicated with different coloured shading. Non-Azorean Reteporella species are indicated by dashed coloured lines. Geographical origins of Reteporella samples are given as terminal labels. Other phidoloporids included in the analyses are identified with colour coding. The scale bar represents substitutions per site. Reteporella species boundaries inferred with bPTP and mPTP approaches, conducted on the single locus COI maximum-likelihood tree, are plotted on the right-hand side
