Morphometric measurements of Pseudo-nitzschia subpacifica in the present study, compare to previous reports.
Each species listed possesses a central nodule.

Tree topology inferred from ML based on the Pseudo-nitzschia ITS2 rDNA.
The nodal supports are bootstrap values of Maximum Likelihood (ML), and Posterior Probability of Bayesian inference (BI). Values of 100% are marked with thick lines. “-” indicate bootstrap support of < 85%.
