Bayesian 50% majority rule consensus tree inferred from the 28S rDNA D2-D3 sequences of Longidorella (Saevadorella) caspica n. sp. under the GTR + G + I model. Bayesian posterior probabilities (BPP) and maximum likelihood bootstrap (ML BS) values > 0.50 are given for appropriate clades in the form: BPP/ML BS. The newly generated species is in bold font.
