The captain of an Ankari ship
The Ankari are a spacefaring humanoid civilization in the Delta Quadrant. They have access to warp technology, but use a form of propulsion that is difficult for sensors to detect. They harbored a great respect for what they termed "spirits of good fortune", nucleogenic lifeforms from another realm, which they could summon using a summoning beacon.
The crew of the stranded USS Equinox encountered the Ankari sometime before 2376, who provided them with supplies and food. They also summoned the lifeforms in their sacred ritual to bless the Equinox's journey. The Equinox crew members were able to barter for one of the devices to summon the lifeforms themselves.
In 2376, the USS Voyager sought out the Ankari for help in negotiating with the lifeforms, who were attacking them as a result of the Equinox crew's actions. (VOY: "Equinox", "Equinox, Part II")
At least one member of the Ankari species was seen in the audience of several Tsunkatse matches. (VOY: "Tsunkatse")

Background
There is some confusion about the Ankari: it is stated that the Ankari were the race of beings who introduced the crew of the Equinox to the nucleogenic lifeforms, which allowed the ship to travel 10,000 light years in two weeks, and possibly further. Yet in Part II, Janeway states that the Ankari are only fifty light years behind them. One explanation could be that the race had colonized planets throughout the quadrant, even over that grand a distance.
