Fig. 4.

18S rDNA-based maximum likelihood (GTR + Γ model) tree of Sphaerospora spp. from fish from the order Cypriniformes, with Sphaerospora truttae used as the outgroup. Newly sequenced taxa are in bold. Maximum likelihood/maximum parsimony/Bayesian inference support values are shown at every node. Dashes indicate < 50 nodal support values or a node missing in the maximum parsimony and Bayesian inference analyses. The original length of long branches was shortened to 50% of their original length (indicated as -//-). Superscript letters at the end of the species names indicate their attribution to the particular family (C, Cyprinidae; G, Gobionidae; L, Leuciscidae; X, Xenocyprididae)
