Bayesian 50% majority rule consensus tree inferred from 64 sequences of 18S rDNA (GenBank accession number and species name) under the GTR+G+I model. Bayesian posterior probabilities and maximum likelihood bootstrap values are given for appropriate clades in the form of BPP/ML BS. The new species is in bold.
