Fig. 2 in First report of a member of the family Mermithidae parasitizing the sandhopper Orchestoidea tuberculata (Amphipoda, Talitridae) in Chile
Fig. 2. Genealogical relationships of haplotypes based on partial sequences of the mitochondrial cytochrome oxidase I (COI) (A) and 18S ribosomal DNA (B) gene sequences of specimens of the family Mermithidae recovered in a Bayesian inference analysis. Numbers next to nodes refer to support values. Bayesian posterior probability values are shown left of the diagonal. Bootstrap support values found in the Maximum Likelihood analysis are shown right of the diagonal. Accession numbers from GenBank are included in the terminal labels. Sequences in red were generated in this study. (For interpretation of the references to colour in this figure legend, the reader is referred to the Web version of this article.)
