Fig. 3.

18S rDNA-based maximum likelihood (GTR + Γ model) tree of the Sphaerospora (sensu stricto) clade. Tetracapsuloides bryosalmonae was used as the outgroup. Newly sequenced taxa are in bold. Maximum likelihood/maximum parsimony/Bayesian inference nodal supports 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 vertebrate host families indicate the host types (P, piscine; and A, amphibian). Abbreviations: F, freshwater; M, marine; CA, California, USA; CZ, Czech Republic; DN, Denmark; FL, Florida, USA; HU, Hungary; IT, Italy; JP, Japan; OR, Oregon, USA; SC, South China Sea; SL, Scotland; TL, Thailand; TN, Tanzania
