Morphology and molecular phylogeny of Gomphonemopsis sieminskae sp. nov. isolated from brackish waters of the East China Sea coast
We describe the new species Gomphonemopsis sieminskae from brackish waters of the East China Sea littoral near Ningbo, China. Two diatom strains isolated from Ulva sp. were successfully grown, then analyzed by light (LM) and scanning electron (SEM) microscopy. The new species is compared to known Go...

| description | We describe the new species Gomphonemopsis sieminskae from brackish waters
of the East China Sea littoral near Ningbo, China. Two diatom strains isolated from Ulva
sp. were successfully grown, then analyzed by light (LM) and scanning electron (SEM)
microscopy. The new species is compared to known Gomphonemopsis species, and similarities
to G. pseudoexigua and G. obscurum are emphasized. Although the size metric data
overlap and the external views are fairly similar, the two taxa differ in their valve interior.
Molecular barcoding strongly discriminated G. sieminskae from G. cf. exigua, while rbcL
gene-based phylogeny showed G. sieminskae to be sister to Phaeodactylum tricornutum.
In this respect our results confirm the recent discovery, based on molecular data, that Gomphonemopsis
is a close-relative taxon to Phaeodactylum, and place it in Phaeodactylaceae
instead of Rhoicospheniaceae as inferred solely from morphology. |
