How can an anostraca be a crustacean?

Why do you think it’s not a crustacean?
Are you aware that, cladistically speaking, insects are crustaceans?
As in, wasps, ants, beetles, bees, assassin bugs, butterflies, etc, they’re all crustaceans?

They're in a category that can be called, with controversy, pancrustacea but they're not part of the subphylum crustacea. So they're not crustaceans.

I think all the division below arthropod is stupid so I'm not sure. But having something without a crusta as a crustacean is ridiculous

Bribe shrimp are in the crustacean clade. So are insects. They’re not just pancrustaceans but actually crustaceans.

You don’t understand cladistics. In cladistic taxonomy, relation is the ONLY thing that matters. NO TRAITS or morphology or anything else matters. Humans are cladistically lobe-finned fish still.

Crustacean isn't a clade, it's a subphylum. Bribe shrimp are in that subphylum but no insect is (because that's a class under the subphylum hexapod).

Alright. But I don't have a problem with insects and bribe shrimp being on the pancrustacea (bad name) clade. I have a problem with bribe shrimp being on the crustacean subphylum when, assuming that is organized by traits, they don't have the one characteristic that makes the term. Meanwhile beetles have a crusta but got lost because they were characterized by number of legs on that same level

Non-cladistic taxonomy is wrong and outdated. You’ll notice that wasps are defined similarly. A wasp is anything in the clade Apocrita that ISNT a bee or ant, so things that are most closely related to ants are wasps, things that are most closely related to bees are wasps, and things distantly related to both but still in Apocrita is a wasp too. This is similar to how hexapods are a sister clade to xenocarids, embedded well within pancrustacea, but not typically classed as crustaceans themselves because “crustacean” is basically a junk taxon.

It’s more a case of “Anything in pancrustacea that’s not a hexapod is a crustacean”. Bribe shrimp aren’t insects but they’re in pancrustacea so they get tossed into “Crustacea”.
