[Taxacom] Call for proxy votes for the forthcoming International Botanical Congress

well, an extant *species*, Triops cancriformis, is perhaps 300 MY! 

a genus is just a convenient monophyletic group, not a real entity, and 
"convenience" is very salient in the case of Drosophila

>and needs to have 100+ secondary homonyms resolved
yes, but they will all be obscure species. Whichever way you jump, there has to 
be some cost ...

That is an option. Drosophila currently would be 2250-2300 species, very 
heterogeneous, 60 million years old, and needs to have 100+ secondary 
homonyms resolved. How many 60 MY old genera are there?
