Re: paleonet Origin of genus Globigerinellopsis and species Globigerinellopsis mitra

["Robert Huber" <robert.huber@xxxxxxxxxxxxxxxx>]

Dear Peter,

Thank you for your kind words, however I think it has to be taken
quite serious when taxon names are used without reference and
I have to confess I still worry a bit about the primary origin of
this name.. ;) 
...And I am still interested if anybody knows about the origin of
the species and/or genus?

In fact I see a big problem when taxon names are used without
systematic section explaining the authors taxonomic concept. 
In the particular example it would mean that the data referrring to
the G. mitra used in this paper is useless, unless it cannot be
clarified which taxon was meant - the experiment cannot be repeated.

best regards,
Robert
