Alfonso,
You have truly chosen a Hurculean task! A chart as you envision to just the
genus level would be extremely tough to complete with any kind of accuracy;
but to the species level??!!! I believe you will end up with numerous
synonyms and may eventually have to designate those species known to be
valid with bold-face or something similar. I, for one, applaud your effort
and wish you the best. Your systematic chart will be a real help once
complete! Congratulations.
