Old original descriptions are often more useful for confirmation of the type
locality and confirming that the specimen labelled as the type really is
either the holotype or syntype. I have found several specimens with HT
labels that are not types at all. In one case that comes straight to mind
the single type specimen was easily identified from the description, but was
labelled as a paratype (which of course couldn't be correct, when the taxon
was named from a single specimen).
Good taxonomists should always check the original descriptions of the taxa
they are working on.
