I’ve seen a few observations of spiders identified as entelegynes (spiders whose female reproductive tract is laid out in a certain way). I can understand looking at a spider and knowing it’s a jumping spider, or an orb-weaver, but not knowing that it’s an entelegyne without knowing the family. How does this happen other than a disagreement?
I don’t know about this specific case, but I put a lot of subclass and superorder IDs when I know it could be X or Y family and Z superorder is the common ancestor. Or if I can rule out subclass A it must be subclass B.

there are some families that look similar to each other but aren’t especially closely related, like Anyphaenidae and Clubionidae, or some members of Amaurobiidae and Agelenidae. close enough to know it isn’t outside of the entelegynae clade.
safer to stick with Araneomorphae generally
