Lysia Arlin was a Bolian woman who ran the jumja stick kiosk on the Promenade aboard Deep Space 9.
In 2370, Jadzia Dax noticed that Lysia had been making a lot of visits to the security office, due to her interest in Odo. Odo, however, claimed that she had only been making those visits because her cousin was interested in law enforcement. (DS9: "Shadowplay")
She was possibly played by uncredited recurring extra Mary Meinel-Newport.
