[Taxacom] Generic type of large genus belongs in different genus

Hi Alan,
        Given that this type species is relatively unknown, and that it is going to cause messes for both the old large genus and the newly named small genus, I would be very tempted to petition the International Commission to have a new type species designated for the larger genus.  This would protect the large genus from many name changes, as well as the new small genus (which already has a type species).  Probably would be best to consult other authorities in advance of such a petition to determine what would be an appropriate choice for the new type species.  I would be hesitant to just let the problem fester waiting for a generic revision that apparently isn't coming anytime in the near future.
