The Byzallians were an alien species.

In 2371, they planned to hold an unspecified conference at Deep Space 9. At some point, they contacted the space station saying they wanted to move the event up by a week. (DS9: "Defiant")

This species was only mentioned in dialogue.
According to the script, Byzallian was pronounced as "buh-ZAY-lee-un".
