Re: Tenthredo arcuata problem
If you search on the Gateway for Tenthredo arcuata, you get two very different maps for
Tenthredo (Tenthredo) arcuata Forster, 1771 TaxonVersionKey: NHMSYS0020705455
and
Tenthredo (Tenthredo) arcuata Förster, 1771 TaxonVersionKey: NHMSYS0020481892
both indicated as good names.
The only difference seems to be an Umlaut on the 'o' in the author.
