It is stephanocha instead of stephanoca, probably just mistake in typing.
I'm so happy to see that silicoflagellate taxonomy is finally going to be done correctly.
Nice work and best wishes to authors.

In nomenclature it should be Dictyocha speculum Ehrenberg 1839. Geological range is the same as D. fibula.
