Alternate Reality(split 2233)
The Teenaxi Delegation (or Teenax Delegation) was the governing body of the Teenaxi. Their homeworld was Teenax.
In 2263 of the alternate reality, they rejected a piece of an artifact called the Abronath, a fact uploaded to the Federation archive later that year. (Star Trek Beyond)
This organization is referred to in dialogue as the "Teenaxi Delegation" but called the "Teenax Delegation" on the Federation archive computer display.
