Garidian

The Garidians were Vulcanoid species from the planet Garid. They led an interstellar government known as the Garidian Republic, near the Romulan Star Empire in the Beta Quadrant. They maintained close ties with the Romulans, and had limited, but not generally hostile, contact with the United Federation of Planets. (TNG : , Star Trek: Banshee Squadron)

Their physical appearance was fairly close to the Vulcan-Romulan norm, however their hair was usually white instead of black or brown.
