Zelonites were a humanoid species and members of the United Federation of Planets during the late 23rd century. Zelonites were distinguished in appearance by their blue skin and tall stature. (Star Trek VI: The Undiscovered Country)
Background information Edit
The name for this species was never mentioned on screen, but is derived from three background sources:
- The call sheets for the scenes in Star Trek VI list the two individuals as Zelonites.
- One of the actors, James Mapes, lists this part as a Zelonite on his resume, 
- It's A Wrap! sale and auction sold parts of the costumes on eBay and gave continuity photographs during the production as the source for this name.
