Latia (Risa)

From Memory Alpha, the free Star Trek reference

Latia was a humanoid who appeared to Commander Tucker and Lieutenant Reed as a beautiful woman, in 2152, when the two officers spent two days shore leave on the planet Risa. She and her friend, Dee'Ahn, set up a date with Tucker and Reed, only to reveal themselves as two male thieves who were in disguise. They robbed Trip and Reed, leaving them tied up in a cellar of a night club. (ENT: "Two Days and Two Nights")

Latia was uncredited played by Dawn Stern and by Stephen Wozniak without her disguise.
