Dear diatomists,
Can someone could say to which Thalassiosira species this diatom belongs? Or it is not a Thalassiosira?
The scale bar is 10 mkm.
Dear Anton:
This diatom is not a Thalassiosira species. See the marginal ring of rimoportulae.
All the best.
Eugenia
Anton:
It looks like Actinocyclus although I don't see characters like the pseudonodule and others. More details would be needed to properly determine the taxon. Consider Hemidiscaceae in Hasle & Syvertsen in Tomas (1996) and Round et al. (1990).
Eugenia< thank you for the answer. I've take a look to these genera.
