Maximum likelihood phylogenetic tree for the Microcotylidae, based on 11 taxa and 947 characters of aligned LSU rDNA sequence data. Non-parametric bootstrap values and Bayesian inference posterior probabilities are shown at the nodes. Bold branches lead to a node with a high bootstrap support of ≥95 and a Bayesian posterior probability of ≥0.98. The tree is rooted to the outgroup Polylabris sillaginae (Woolcock, 1936) Dillon, Hargis et Harrises, 1983. Scale bar represents 0.01 base changes per 100 bases.
