    The last proper recombination I found for this taxon is:

    1998. Dictyococcites stavensis (Levin and Joerger) Varol, p. 218, pl. 7.2, fig. 5.

    in the Black book, but I think Dictyococcitesis a synonim of Reticulofenestra

    I checked in Varol (1989) for the recombination to Reticulofenestra and is not there... I look for the author in other taxonomic works and everybody cites Varol (1989), but there is no recombination of this species in that paper.

    Could it be possible that there is no proper recombination to Reticulofenestra stavensis according to the ICBN??

    Hi Juan

    My mistake the wrong paper was cited here - there four Varol 1989 papers and keeping track of which one is which is always a problem. The correct citation is Varol, O. (1989a). Calcareous nannofossil study of the central and western Solomon Islands. Circum-Pacific Council for Energy and Mineral Resources Earth Sciences. 239-268. There are a few other new species and combinations in that paper so will check the other citations.

    thanks

    Jeremy

    Thanks Jeremy. It looks like that mistake was replicated in several papers, because they cite the one from Revista Española.

    Cheers,

    Juan
