Figure 1. Bayesian tree inferred from the 18S in A molecular analysis of the phylogenetic position of the suborder Cavernicola within the Tricladida (Platyhelminthes), with the description of a new species of stygobiont flatworm from Benin

Figure 1. Bayesian tree inferred from the 18S rDNA sequences showing the relationship of the new Novomitchellia species to other Tricladida species included in this analysis. Maximum likelihood (ML) yielded the same topology. Asterisks at nodes indicate posterior probabilities = 1/bootstrap values> 75% obtained respectively in the ML and Bayesian inference analyses. Scale bar: number of substitutions per nucleotide position.
