[Taxacom] Type localities (was: Bionomina 13 published)

[Kenneth Kinman]

Hi Stephen and Elena,
       The situation that Elena described is not what I would call a "widespread uniform species".  Her example would tend to be a chain of subspecies, each with small but discoverable differences from neighboring populations (even more so from more distant subspecies).  So I would agree that type localities would be important (although I would agree with Stephen that the distribution of the taxa is more important than the type locality itself).
        What I was referring to as "widespread uniform species" would generally be long-distance migratory species, like the monarch butterfly or perhaps even more so the whooping crane.  The type locality of the whooping crane has almost no importance at all, so Stephen and I would agree on that.  However, their is a whole continuum from there to the opposite extreme of a species such as a polyploid plant known only from the small area where it arose, having arisen relatively recently from a diploid ancestor.  The type locality of that recently evolved polyploid would be far more important than the type locality of an albatross or bison, because the distribution of that polyploid would barely extend beyond the type locality.  A chain of subspecies as Elena described is somewhere in between those extremes.
      So I would agree with Stephen that the distributions are always going to be more important than the type locality, but I wouldn't be so willing to be so forceful in minimizing the importance of type localities to some researchers, especially those who study rare taxa with very limited distributions.  It's a contiuum, but a very wide one, so the importance of type localities will also be a continuum, even though their distributions beyond the type locality will always be more important.

Not quite! The type localities per se still aren't important in the situation you describe. What matters is the distributions of the segregate species in the complex.

 Oh, really? Except for the most common
 situation in shallow-water marine invertebrates. Once one
 actually bothers to look more or less carefully at this
 "common, widespread uniform species" and discovers a huge
 species complex beyond the façade of this "common" or even
 "cosmopolitan species", the importance of the type
 localities somehow becomes crystal clear.
