FIGURE 2 in Polka-dotted treasures: Revising a clade of ascidian- and bivalve-associated shrimps (Caridea: Palaemonidae)
FIGURE 2 Phylogeny reconstruction based on the MrBayes tree topology of the TE approach. RAxML bootstrap support and Bayesian posterior probabilities expressed as percentages are indicated respectively. Dashes (--) indicate values <50; asterisk (*) indicates different topology of RAxML or MrBayes tree. Barcodes are indicated by a collection accession number (RMNH.CRUS.D.) or a GenBank accession number. Species are listed in the appendices (supplementary table S1). Species of which only morphological data was analysed are indicated with an asterisk (*) and no accession number. Colours indicate various host associations. Zenopontonia rex (Kemp, 1922) is represented as a symbiont with two main host associations: holothurians and nudibranchs.

FIGURE 3 in Polka-dotted treasures: Revising a clade of ascidian- and bivalve-associated shrimps (Caridea: Palaemonidae)
FIGURE 3 Phylogeny reconstruction based on the MrBayes tree topology of the TE approach (fig. 2), with ancestral character state reconstructions on the internal nodes (probabilities are shown as pie charts). Colours indicate various host associations, both for the species as well as the ancestral character states. Zenopontonia rex (Kemp, 1922) is represented as a symbiont with two kinds of host associations (holothurians and nudibranchs), but was only classified as an echinoderm associate in the analysis. Species of which only morphological data was analysed are indicated with an asterisk next to the species names (*).
