Fig. 1 Tree resulting from Bayesian Inference (BI) analysis of partial (D1-D3 domains) of lsrDNA data for selected members of the Proteocephalidae, including Riggenbachiella amazonense n. sp. and Chambriella megacephala (Woodland, 1934) n. comb. Bayesian inference posterior probabilities/ Maximum likelihood (ML) bootstrap support values are shown at the nodes. Branches with posterior probability support \ 0.90 (BI) are collapsed and support values \ 70 (ML) are not shown. The scale-bar indicates the number of substitutions per site
FIGURE 1 in Molecular data support monophyly of the recently erected Riggenbachiella (Cestoda: Proteocephalidae), parasites of Neotropical catfishes
FIGURE 1. Phylogram based on maximum likelihood (ML) analysis of partial (D1–D3 domains) of lsrDNA data for species of Riggenbachiella and other selected members of the Proteocephalidae. Taxon names are followed by their voucher accession number, host species, and GenBank accession numbers. Clades C and K (three representatives as outgroup) of de Chambrier et al. (2015) are shown at early nodes. Newly generated sequences are in bold.
