Maybe this is a FAQ but I didn’t find it there. Consider the following situation: Observer ID’s own spider-like specimen as harvestman. Somebody else sees it, disagrees and says Leucauge (which is in orbweavers+allies), which correctly puts the obs into Arachnida. I see it, but I lack the qualification for Leucauge, all I could say is Araneomorphae (i.e. non-tarantula spiders).
Should I enter this or will it harm the Leucauge ID more than it helps destroying the Opiliones one?
It still is Arachnida and the “What’s this” explains why: 2×spider isn’t enough to overrule 1×harvestman, so it sticks with the parent taxon until a third person comes and says it’s a spider.
But this was not why I asked. I was just afraid of harming somebody else’s genus level ID with my infraorder one, but that didn’t happen.
