Such diversity of opinion!
Distributions may be subject to change, but that doesn't make them less important!!
Type localities may be subject to vagueness (e.g. "Type locality: New Zealand") or error (e.g. several species have N.Z. as their stated type locality but are not actually found here, e.g. Carneiola zealandica, which is probably an obscure South African species!)
Localities for any specimen are important, but type localities are no more important than locality data for any specimen.

than the type locality itself"
No Ken, it is not, at least not for taxonomy -
ecology is another matter.
Distributions are
ephemeral, changing seasonally and with climate. type
localities are permanent, and useful, as
starting points, even for
migratory birds
and butterflies.
"Where I found it I do not remember."
(Hans Sloane 1725: v. 2 p. 194).
Love that
quote. Try saying that in a paper today.
