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

[Richard Jensen]

Names of taxa should be, and generally are, meaningful.  As Mayr noted 
years ago, knowing the genus of a fruit fly allowed one to predict a 
great many characters of the fly (i.e., why it is a fruit fly).  If 
names had no meaning, that would not be possible.

If you have no other way of conveying relationships then perhaps the trade off between stability and meaning seems worthwhile. But we do have powerful ways of visualising relationships, so it seems perverse to continue to change names (thus annoying people who use them) in the hope that names remain "meaningful". We don't expect the name of an organism to be meaningful ("maximus" might not be the biggest species, "africanus" might come from Australia), can we not let this last scrap of meaning go and save us (and the wider community) some grief?
