Maximum likelihood tree calculated from SSU rRNA Class II by the Mega program with the T92?+?? model. The alignment of 58 sequences of LSU rRNA was 1119 base pairs long. The lnL value of this optimal tree was ?4073.31. Support values obtained using different reconstruction approaches are indicated at nodes in the following order: maximum Likelihood bootstrap probabilities (bv), approximative likelihood ratio test (aLRTv) and Bayesian posterior probabilities (pp). Support values are displayed when bv/aLRTv ?75 or pp ?0.85. Node absence in a given method is indicated by -. Tree was rooted on the monophyletic assemblage consisting of Eukrohniidae?+?Heterokrohniidae. This rooting was also observed in most analyses when using the midpoint rooting function.
