Genealogical relationships of haplotypes based on partial COI (A) and 18S (B) gene sequences of specimens of the genus Profilicollis recovered in a Bayesian inference analysis. Numbers next to nodes refer to support values. Bayesian posterior probability values are shown left, and Bootstrap proportions gathered in the Maximum Likelihood analysis (COI: Ln = −2599.057, 18S: Ln = −3574.388). GenBank accession numbers are included in the terminal labels. Animal silhouettes with different box colors to the right of the trees indicate the intermediate host (IH) of each species. Blue = A. abtao; Green = Emerita spp.; Orange = Varunidae; Red = Portunidae.
