Abstract:
Pseudo‐nitzschia nanaoensis sp. nov. is described from waters around Nan'ao Island (South China Sea), using morphological data and molecular evidence. This species is morphologically most similar to P. brasiliana , but differs by a denser arrangement of fibulae, interstriae, and poroids, as well as by the structure of the valvocopula and the narrow second band. Pseudo‐nitzschia nanaoensis constitutes a monophyletic lineage and is well differentiated from other species on the LSU and ITS 2 sequence‐structure trees. Pseudo‐nitzschia nanaoensis makes up the basal node on the LSU tree, and forms a sister clade with a group of P. pungens and P. multiseries on the ITS2 tree. The ability of cultured strains to produce domoic acid was assessed, including its possible induction by the presence of a copepod and brine shrimp, by liquid chromatography–tandem mass spectrometry. However, no strains showed detectable domoic acid.
