Bayesian topology based on partial LSU rDNA sequences of Cichlidogyrus Paperna, 1960 and Scutogyrus Pariselle & Euzet, 1995 species. GenBank accession numbers are after species names. Newly sequenced species are in bold. The support values are included above the nodes as follows: posterior probabilities for BI analysis, followed by bootstraps for the ML analysis. Only nodes with posterior probabilities >0.90 and bootstrap scores >70 are considered well-supported. Dashes before nodes represent clades that were not recovered by both analyses. Branch length scale bar indicates the number of substitutions per site.
