List of unnamed Dopterians.
Patron
This Dopterian visited a bar on Farius Prime in 2374. (DS9: "Honor Among Thieves")
Pickpocket
In 2369, Constable Odo correctly deduced that this Dopterian pickpocket was responsible for the petty theft of Ambassador Lwaxana Troi's latinum hair brooch aboard Deep Space 9, since she was unable to discern any emotions of guilt in her surroundings. After he was arrested he put all stolen items on the table, including a Bajoran earring, a Starfleet combadge, and a necklace. (DS9: "The Forsaken")
Thief
In 2372, this Dopterian thief broke in numerous living quarters aboard Deep Space 9, including those of Lieutenant Commander Worf. He was discovered by Worf moving through a crawlspace near his quarters and was subsequently arrested. (DS9: "Bar Association")
Waiter
The Dopterian waiter was at Quark's in 2373, when a Cardassian-Dominion delegation, led by Gul Dukat and Weyoun 5 visited the Promenade. (DS9: "Ties of Blood and Water")
