Wysanti
From Memory Alpha, the free Star Trek reference
The Wysanti are a humanoid species native to the planet Wysanti in the Delta Quadrant, distinguished by a midline ridge on the forehead. (VOY: "Collective")
The Wysanti do not believe in saying good-bye. At least a few members of the Wysanti species have been assimilated by the Borg.
In 2377, USS Voyager rendezvoused with a Wysanti starship. They offered to return Azan and Rebi to their people, and they accepted. Mezoti also decided to go with them, and wished Icheb would come as well, but he felt his place was on Voyager. (VOY: "Imperfection")
