Phylogenetic relationship of Codosiga balthica and C. minima within Craspedida based on partial 28S rRNA sequences excluding the fast evolving divergent D2 region using MrBayes. Posterior probability and bootstrap values above 0.5 and 50 are shown. Scale bar represents 0.1 mutations per position. Values above 0.99 and 99 are presented as bold face branches. Scale bar represents 0.1 mutations per position. Amoebidium parasiticum (Ichthyosporea) was used as outgroup representative.
