Daliwakan

The Daliwakans were a humanoid species native to the Alpha or Beta Quadrant.

The Daliwakans largely resembled Human in appearance, except for a row of ridges down the center of their forehead, and pronounced skin above the eyebrows. Daliwakans could reproduce with Humans.

Presumably, "The Gigolo's" features are a combination of Human and Daliwakan facial features, so a Daliwakan's appearance would probably be more pronounced than his.

There was a hologram (presumably based upon a real person) who was half-Daliwakan on his mother's side, while his father was a Human of French descent. He was included in Tom Paris' holodeck program depicting Chez SandrĂ­ne, his flirtatious and overtly forward behavior was remarked to be indicative of both his Daliwakan and French heritage.

The Star Trek: Star Charts ("United Federation of Planets I") listed a planet named Daliwaka, which might possibly be the homeworld of species, as a Federation member in 2378.
