Altoran

The Altorans were a species known to engage in trade.

In 2369, Ah-Kel claimed to have acquired an object from an Altoran trader, rather than admit their involvement in its theft. (DS9: "Vortex")

This species was only mentioned in dialogue.

According to StarTrek.com, Altora was the homeworld of the Altorans. [1]^(X)
