Actually, there are lots of species with no type specimen, and many
genera with no type species (dubious or otherwise). Percentage-wise,
both occurrences are perhaps rare, but the absolute numbers are
significant. BEST PRACTICE is to follow the Code, and the Code does not
*require* stabilization through typification unless there is confusion.
This is at the core of a lot of ongoing controversy, but I and perhaps
most Commissioners seem to be okay with the "If it ain't broke, don't
fix it" approach here.
If there is a genuine risk of a genus name being misapplied unless a
type species is fixed, then yes, do it. Otherwise, don't worry.
