I think this is something that has not been discussed before & is important:
What is your taxonomy resource?
As hopper identifier, I refer to hoppers speciesfile (hoppers.speciesfile.org) & in the past FLOW too (the website is down nowadays but although it only dealt with planthoppers it was often more accurate)
But there are numerous taxa where there is no taxonomy reseource so you have to dig up everything.
THE RULES:
Mention your resource only if it has not been mentioned of, especially those which are useful in your taxonomic group of expertise, and if it has been mentioned before, you should not repeat, at most just like the one which mentions your resource.
