[Taxacom] New Paper on Mollusca

       Well, I certainly think geographic distribution can be potentially very informative, as my comment on Antarctica clearly demonstrates.  However, this paper is not what I would call a monograph (not even of a subgenus, much less a genus), so if you have an axe to grind about monographs lacking maps, why pick on a non-monograph to vent your biogeographer's frustration?  Shouldn't expect every new species description to have a map showing distributions of the entire genus.  Such great expectations are often unrealistic, which can result in disappointment.
