Author A is correct - from your presentation of the situation. The wus name
can only rest with the holotype. IF that type specimen came from within the
range of xus then it is indeed a junior synonym without question. Any other
type specimens (paratypes or syntypes), regardless of actual subspecific
affinity, are irrelevant. They would be nomen dubium - of doubtful
application in association with the epithet wus.
